Christian culture is the cultural practices common to Christianity. With the rapid expansion of Christianity to Europe, Syria, Mesopotamia, Asia Minor, Egypt, Ethiopia, and India and by the end of the 4th century it had also become the official state church of the Roman Empire. Christian culture has influenced and assimilated much from the Greco-Roman Byzantine, Western culture, Middle Eastern, Slavic, Caucasian, and possibly from Indian.
Western culture, throughout most of its history, has been nearly equivalent to Christian culture, and many of the population of the Western hemisphere could broadly be described as cultural Christians. The notion of "Europe" and the "Western World" has been intimately connected with the concept of "Christianity and Christendom" many even attribute Christianity for being the link that created a unified European identity. Historian Paul Legutko of Stanford University said the Catholic Church is "at the center of the development of the values, ideas, science, laws, and institutions which constitute what we call Western civilization."
Though Western culture contained several polytheistic religions during its early years under the Greek and Roman Empires, as the centralized Roman power waned, the dominance of the Catholic Church was the only consistent force in Western Europe. Until the Age of Enlightenment, Christian culture guided the course of philosophy, literature, art, music and science. Christian disciplines of the respective arts have subsequently developed into Christian philosophy, Christian art, Christian music, Christian literature etc. Art and literature, law, education, and politics were preserved in the teachings of the Church, in an environment that, otherwise, would have probably seen their loss. The Church founded many cathedrals, universities, monasteries and seminaries, some of which continue to exist today. Medieval Christianity created the first modern universities. The Catholic Church established a hospital system in Medieval Europe that vastly improved upon the Roman valetudinaria. These hospitals were established to cater to "particular social groups marginalized by poverty, sickness, and age," according to historian of hospitals, Guenter Risse. Christianity also had a strong impact on all other aspects of life: marriage and family, education, the humanities and sciences, the political and social order, the economy, and the arts.
Christianity had a significant impact on education and science and medicine as the church created the bases of the Western system of education, and was the sponsor of founding universities in the Western world as the university is generally regarded as an institution that has its origin in the Medieval Christian setting. Many clerics throughout history have made significant contributions to science and Jesuits in particular have made numerous significant contributions to the development of science. The cultural influence of Christianity includes social welfare, founding hospitals, economics (as the Protestant work ethic), natural law (which would later influence the creation of international law), politics, architecture, literature, personal hygiene, and family life. Christianity played a role in ending practices common among pagan societies, such as human sacrifice, slavery, infanticide and polygamy.
Christians have made a myriad contributions to human progress in a broad and diverse range of fields, both historically and in modern times, including the science and technology, medicine, fine arts and architecture, politics, literatures, music, philanthropy, philosophy,:15 ethics, theatre and business. According to 100 Years of Nobel Prizes a review of Nobel prizes award between 1901 and 2000 reveals that (65.4%) of Nobel Prizes Laureates, have identified Christianity in its various forms as their religious preference. Eastern Christians (particularly Nestorian Christians) have also contributed to the Arab Islamic Civilization during the Ummayad and the Abbasid periods by translating works of Greek philosophers to Syriac and afterwards to Arabic. They also excelled in philosophy, science, theology and medicine.
Cultural Christians are secular people with a Christian heritage who may not believe in the religious claims of Christianity, but who retain an affinity for the popular culture, art, music, and so on related to it. Another frequent application of the term is to distinguish political groups in areas of mixed religious backgrounds

The architecture of cathedrals, basilicas and abbey churches is characterised by the buildings' large scale and follows one of several branching traditions of form, function and style that all ultimately derive from the Early Christian architectural traditions established in the Constantinian period.
Cathedrals in particular, as well as many abbey churches and basilicas, have certain complex structural forms that are found less often in parish churches. They also tend to display a higher level of contemporary architectural style and the work of accomplished craftsmen, and occupy a status both ecclesiastical and social that an ordinary parish church does not have. Such a cathedral or great church is generally one of the finest buildings within its region and is a focus of local pride. Many cathedrals and basilicas, and a number of abbey churches are among the world's most renowned works of architecture. These include St. Peter's Basilica, Notre Dame de Paris, Cologne Cathedral, Salisbury Cathedral, Prague Cathedral, Lincoln Cathedral, the Basilica of St Denis, the Basilica of Santa Maria Maggiore, the Basilica of San Vitale, St Mark's Basilica, Westminster Abbey, Saint Basil's Cathedral, Washington National Cathedral, Basilica of the National Shrine of the Immaculate Conception, Cathedral Basilica of Saint Louis, Gaudí's incomplete Sagrada Familia and the ancient church of Hagia Sophia, now a museum.
The earliest large churches date from Late Antiquity. As Christianity and the construction of churches and cathedrals spread throughout the world, their manner of building was dependent upon local materials and local techniques. Different styles of architecture developed and their fashion spread, carried by the establishment of monastic orders, by the posting of bishops from one region to another and by the travelling of master stonemasons who served as architects. The styles of the great church buildings are successively known as Early Christian, Byzantine, Romanesque, Gothic, Renaissance, Baroque, various Revival styles of the late 18th to early 20th centuries and Modern. Overlaid on each of the academic styles are the regional characteristics. Some of these characteristics are so typical of a particular country or region that they appear, regardless of style, in the architecture of churches designed many centuries apart.
Christian art is sacred art which uses themes and imagery from Christianity. Most Christian groups use or have used art to some extent, although some have had strong objections to some forms of religious image, and there have been major periods of iconoclasm within Christianity.
Images of Jesus and narrative scenes from the Life of Christ are the most common subjects, and scenes from the Old Testament play a part in the art of most denominations. Images of the Virgin Mary and saints are much rarer in Protestant art than that of Roman Catholicism and Eastern Orthodoxy.
Christianity makes far wider use of images than related religions, in which figurative representations are forbidden, such as Islam and Judaism. However, there is also a considerable history of aniconism in Christianity from various periods.
An illuminated manuscript is a manuscript in which the text is supplemented by the addition of decoration. The earliest surviving substantive illuminated manuscripts are from the period AD 400 to 600, primarily produced in Ireland, Constantinople and Italy. The majority of surviving manuscripts are from the Middle Ages, although many illuminated manuscripts survive from the 15th century Renaissance, along with a very limited number from Late Antiquity.
Most illuminated manuscripts were created as codices, which had superseded scrolls; some isolated single sheets survive. A very few illuminated manuscript fragments survive on papyrus. Most medieval manuscripts, illuminated or not, were written on parchment (most commonly of calf, sheep, or goat skin), but most manuscripts important enough to illuminate were written on the best quality of parchment, called vellum, traditionally made of unsplit calfskin, though high quality parchment from other skins was also called parchment.
Christian art began, about two centuries after Christ, by borrowing motifs from Roman Imperial imagery, classical Greek and Roman religion and popular art. Religious images are used to some extent by the Abrahamic Christian faith, and often contain highly complex iconography, which reflects centuries of accumulated tradition. In the Late Antique period iconography began to be standardised, and to relate more closely to Biblical texts, although many gaps in the canonical Gospel narratives were plugged with matter from the apocryphal gospels. Eventually the Church would succeed in weeding most of these out, but some remain, like the ox and ass in the Nativity of Christ.
An icon is a religious work of art, most commonly a painting, from Orthodox Christianity. Christianity has used symbolism from its very beginnings. In both East and West, numerous iconic types of Christ, Mary and saints and other subjects were developed; the number of named types of icons of Mary, with or without the infant Christ, was especially large in the East, whereas Christ Pantocrator was much the commonest image of Christ.
Christian symbolism invests objects or actions with an inner meaning expressing Christian ideas. Christianity has borrowed from the common stock of significant symbols known to most periods and to all regions of the world. Religious symbolism is effective when it appeals to both the intellect and the emotions. Especially important depictions of Mary include the Hodegetria and Panagia types. Traditional models evolved for narrative paintings, including large cycles covering the events of the Life of Christ, the Life of the Virgin, parts of the Old Testament, and, increasingly, the lives of popular saints. Especially in the West, a system of attributes developed for identifying individual figures of saints by a standard appearance and symbolic objects held by them; in the East they were more likely to identified by text labels.
Each saint has a story and a reason why he or she led an exemplary life. Symbols have been used to tell these stories throughout the history of the Church. A number of Christian saints are traditionally represented by a symbol or iconic motif associated with their life, termed an attribute or emblem, in order to identify them. The study of these forms part of iconography in Art history.
Eastern Christian art
The dedication of Constantinople as capital in 330 AD created a great new Christian artistic centre for the Eastern Roman Empire, which soon became a separate political unit. Major Constantinopolitan churches built under Constantine and his son, Constantius II, included the original foundations of Hagia Sophia and the Church of the Holy Apostles. As the Western Roman Empire disintegrated and was taken over by "barbarian" peoples, the art of the Byzantine Empire reached levels of sophistication, power and artistry not previously seen in Christian art, and set the standards for those parts of the West still in touch with Constantinople.
This achievement was checked by the controversy over the use of graven images, and the proper interpretation of the Second Commandment, which led to the crisis of Iconoclasm or destruction of religious images, which racked the Empire between 726 and 843. The restoration of Orthodoxy resulted in a strict standardization of religious imagery within the Eastern Church. Byzantine art became increasingly conservative, as the form of images themselves, many accorded divine origin or thought to have been be painted by Saint Luke or other figures, was held to have a status not far off that of a scriptural text. They could be copied, but not improved upon. As a concession to Iconoclast sentiment, monumental religious sculpture was effectively banned. Neither of these attitudes were held in Western Europe, but Byzantine art nonetheless had great influence there until the High Middle Ages, and remained very popular long after that, with vast numbers of icons of the Cretan School exported to Europe as late as the Renaissance. Where possible, Byzantine artists were borrowed for projects such as mosaics in Venice and Palermo. The enigmatic frescoes at Castelseprio may be an example of work by a Greek artist working in Italy.
The art of Eastern Catholicism has always been rather closer to the Orthodox art of Greece and Russia, and in countries near the Orthodox world, notably Poland, Catholic art has many Orthodox influences. The Black Madonna of Częstochowa may well have been of Byzantine origin – it has been repainted and this is hard to tell. Other images that are certainly of Greek origin, like the Salus Populi Romani and Our Lady of Perpetual Help, both icons in Rome, have been subjects of specific veneration for centuries.
Although the influence has often been resisted, especially in Russia, Catholic art has also affected Orthodox depictions in many respects, especially in countries like Romania, and in the post-Byzantine Cretan School, which led Greek Orthodox art under Venetian rule in the 15th and 16th centuries. El Greco left Crete when relatively young, but Michael Damaskinos returned after a brief period in Venice, and was able to switch between Italian and Greek styles. Even the traditionalist Theophanes the Cretan, working mainly on Mount Athos, nevertheless shows unmistakable Western influence.
Many Eastern Orthodox states in Eastern Europe, as well as to some degree the Muslim states of the eastern Mediterranean, preserved many aspects of the empire's culture and art for centuries afterward. A number of states contemporary with the Byzantine Empire were culturally influenced by it, without actually being part of it (the "Byzantine commonwealth"). These included Bulgaria, Serbia, and the Rus, as well as some non-Orthodox states like the Republic of Venice and the Kingdom of Sicily, which had close ties to the Byzantine Empire despite being in other respects part of western European culture. Art produced by Eastern Orthodox Christians living in the Ottoman Empire is often called "post-Byzantine." Certain artistic traditions that originated in the Byzantine Empire, particularly in regard to icon painting and church architecture, are maintained in Greece, Serbia, Bulgaria, Macedonia, Russia and other Eastern Orthodox countries to the present day.
Roman Catholic art
Roman Catholic art consists of all visual works produced in an attempt to illustrate, supplement and portray in tangible form the teachings of the Catholic Church. This includes sculpture, painting, mosaics, metalwork, embroidery and even architecture. Catholic art has played a leading role in the history and development of Western Art since at least the fourth century. The principal subject matter of Catholic Art has been the life and times of Jesus Christ, along with those of his disciples, the saints, and the events of the Jewish Old Testament.
The earliest surviving art works are the painted frescoes on the walls of the catacombs and meeting houses of the persecuted Christians of the Roman Empire. The Christian Church in Rome was influenced by the Roman style of art and the religious Christian artists of the time. The stone sarcophagi of Roman Christians exhibit the earliest surviving carved statuary of Jesus, Mary and other biblical figures. The legalisation of Christianity transformed Catholic art, which adopted richer forms such as mosaics and illuminated manuscripts. The iconoclasm controversy briefly divided the eastern and western churches, after which artistic development progressed in separate directions. Romanesque and Gothic art flowered in the Western Church as the style of painting and statuary moved in an increasingly naturalistic direction. The Protestant Reformation produced new waves of image-destruction, to which the Church responded with the dramatic and emotive Baroque and Rococo styles. In the 19th century the leadership in western art moved away from the Catholic Church which, after embracing historical revivalism was increasingly affected by the modernist movement, a movement that in its "rebellion" against nature, counters the Church's emphasis on nature as a good creation of God.
Renaissance artists such as Raphael, Michelangelo, Leonardo da Vinci, Bernini, Botticelli, Fra Angelico, Tintoretto, Caravaggio, and Titian, were among a multitude of innovative virtuosos sponsored by the Church.
British art historian Kenneth Clark wrote that Western Europe's first "great age of civilisation" was ready to begin around the year 1000. From 1100, he wrote, monumental abbeys and cathedrals were constructed and decorated with sculptures, hangings, mosaics and works belonging one of the greatest epochs of art and providing stark contrast to the monotonous and cramped conditions of ordinary living during the period. Abbot Suger of the Abbey of St. Denis is considered an influential early patron of Gothic architecture and believed that love of beauty brought people closer to God: "The dull mind rises to truth through that which is material". Clarke calls this "the intellectual background of all the sublime works of art of the next century and in fact has remained the basis of our belief of the value of art until today".
Later, during The Renaissance and Counter-Reformation, Catholic artists produced many of the unsurpassed masterpieces of Western art – often inspired by Biblical themes: from Michelangelo's David and Pietà sculptures, to Da Vinci's Last Supper and Raphael's various Madonna paintings. Referring to a "great outburst of creative energy such as took place in Rome between 1620 and 1660", Kenneth Clarke wrote:
[W]ith a single exception, the great artists of the time were all sincere, conforming Christians. Guercino spent much of his mornings in prayer; Bernini frequently went into retreats and practised the Spiritual Exercises of Saint Ignatius; Rubens attended Mass every morning before beginning work. The exception was Caravaggio, who was like the hero of a modern play, except that he happened to paint very well. This conformism was not based on fear of the Inquisition, but on the perfectly simple belief that the faith which had inspired the great saints of the preceding generation was something by which a man should regulate his life.
Catholics have also given greater value to the world through literary works by Dante Alighieri, Geoffrey Chaucer, John Dryden, Walker Percy, Jack Kerouac, Evelyn Waugh, Alexander Pope, Honoré de Balzac, Oscar Wilde, Thomas Merton, Toni Morrison, Ernest Hemingway, J.R.R. Tolkien, G. K. Chesterton, Claude McKay, Paul Verlaine, Graham Greene, Sigrid Undset, Tennessee Williams, Francois Mauriac, Flannery O'Connor, Gerard Manley Hopkins, Paul Claudel, F. Scott Fitzgerald, Michel de Montaigne, Siegfried Sassoon, John Henry Newman, Hugo von Hofmannsthal, Arthur Rimbaud, Joseph Conrad, Miguel de Cervantes, Czeslaw Milosz, Hilaire Belloc, John of the Cross, Luis Vaz De Camoes, Edith Sitwell, Thomas More, among others.
The Protestant Reformation during the 16th century in Europe almost entirely rejected the existing tradition of Catholic art, and very often destroyed as much of it as it could reach. A new artistic tradition developed, producing far smaller quantities of art that followed Protestant agendas and diverged drastically from the southern European tradition and the humanist art produced during the High Renaissance. In turn, the Catholic Counter-Reformation both reacted against and responded to Protestant criticisms of art in Roman Catholicism to produce a more stringent style of Catholic art. Protestant religious art both embraced Protestant values and assisted in the proliferation of Protestantism, but the amount of religious art produced in Protestant countries was hugely reduced. Artists in Protestant countries diversified into secular forms of art like history painting, landscape painting, portrait painting and still life.
Prominent painters with Protestant background were, for example, Albrecht Dürer, Hans Holbein the Younger, Lucas Cranach, Rembrandt, and Vincent van Gogh. World literature was enriched by the works of Edmund Spenser, John Milton, John Bunyan, John Donne, John Dryden, Daniel Defoe, William Wordsworth, Jonathan Swift, Johann Wolfgang Goethe, Friedrich Schiller, Samuel Taylor Coleridge, Edgar Allan Poe, Matthew Arnold, Conrad Ferdinand Meyer, Theodor Fontane, Washington Irving, Robert Browning, Emily Dickinson, Emily Brontë, Charles Dickens, Nathaniel Hawthorne, Thomas Stearns Eliot, John Galsworthy, Thomas Mann, William Faulkner, John Updike, and many others.
Christian music is music that has been written to express either personal or a communal belief regarding Christian life and faith. Common themes of Christian music include praise, worship, penitence, and lament, and its forms vary widely across the world.
Like other forms of music the creation, performance, significance, and even the definition of Christian music varies according to culture and social context. Christian music is composed and performed for many purposes, ranging from aesthetic pleasure, religious or ceremonial purposes, or as an entertainment product for the marketplace.
In music, Catholic monks developed the first forms of modern Western musical notation in order to standardize liturgy throughout the worldwide Church, and an enormous body of religious music has been composed for it through the ages. This led directly to the emergence and development of European classical music, and its many derivatives. The Baroque style, which encompassed music, art, and architecture, was particularly encouraged by the post-Reformation Catholic Church as such forms offered a means of religious expression that was stirring and emotional, intended to stimulate religious fervor.
The list of Catholic composers and Catholic sacred music which have a prominent place in Western culture is extensive, but includes Ludwig van Beethoven's Ode to Joy; Wolfgang Amadeus Mozart's Ave verum corpus; Franz Schubert's Ave Maria, César Franck's Panis angelicus, and Antonio Vivaldi's Gloria.
Martin Luther, Paul Gerhardt, George Wither, Isaac Watts, Charles Wesley, William Cowper, and many other authors and composers created well-known church hymns. Musicians like Heinrich Schütz, Johann Sebastian Bach, George Frederick Handel, Henry Purcell, Johannes Brahms, and Felix Mendelssohn-Bartholdy composed great works of music.

Literature and poetry
Christian literature is writing that deals with Christian themes and incorporates the Christian world view. This constitutes a huge body of extremely varied writing. Christian poetry is any poetry that contains Christian teachings, themes, or references. The influence of Christianity on poetry has been great in any area that Christianity has taken hold. Christian poems often directly reference the Bible, while others provide allegory.
While falling within the strict definition of literature, the Bible is not generally considered literature. However, the Bible has been treated and appreciated as literature; the Bible is a corner stone of Western civilization. The King James Version in particular has long been considered a masterpiece of English prose, whatever may be thought of its religious significance. The Authorized Version has been called "the most influential version of the most influential book in the world, in what is now its most influential language", "the most important book in English religion and culture", and "the most celebrated book in the English-speaking world". David Crystal has estimated that it is responsible for 257 idioms in English, examples include feet of clay and reap the whirlwind. Furthermore, prominent atheist figures such as the late Christopher Hitchens and Richard Dawkins have praised the King James Version as being "a giant step in the maturing of English literature" and "a great work of literature", respectively, with Dawkins then adding, "A native speaker of English who has never read a word of the King James Bible is verging on the barbarian". Several retellings of the Bible, or parts of the Bible, have also been made with the aim of emphasising its literary qualities. With estimated sales of over 5 billion copies, the Bible is widely considered to be the best-selling book of all time. It sells approximately 100 million copies annually, and has been a major influence on literature and history, especially in the West, where the Gutenberg Bible was the first book printed using movable type.
In Byzantine literature, four different cultural elements are recognised: the Greek, the Christian, the Roman, and the Oriental. Byzantine literature is often classified in five groups: historians and annalists, encyclopaedists (Patriarch Photios, Michael Psellus, and Michael Choniates are regarded as the greatest encyclopaedists of Byzantium) and essayists, and writers of secular poetry. The only genuine heroic epic of the Byzantines is the Digenis Acritas. The remaining two groups include the new literary species: ecclesiastical and theological literature, and popular poetry. And it was in Alexandria that Graeco-Oriental Christianity had its birth. There the Septuagint translation had been made; there that that fusion of Greek philosophy and Jewish religion took place which culminated in Philo; there flourished the mystic speculative Neoplatonism associated with Plotinus and Porphyry. At Alexandria the great Greek ecclesiastical writers worked alongside pagan rhetoricians and philosophers; several were born here, e.g. Origen, Athanasius, and his opponent Arius, also Cyril and Synesius. On Egyptian soil monasticism began and thrived. After Alexandria, Antioch held great prestige, where a school of Christian commentators flourished under St. John Chrysostom and where later arose the Christian universal chronicles. In surrounding Syria, we find the germs of Greek ecclesiastical poetry, while from neighboring Palestine came St. John of Damascus, one of the Greek Fathers.
The list of Catholic authors and literary works is vast. With a literary tradition spanning two millennia, the Bible and Papal Encyclicals have been constants of the Catholic canon but countless other historical works may be listed as noteworthy in terms of their influence on Western society. From late Antiquity, St Augustine's book Confessions, which outlines his sinful youth and conversion to Christianity, is widely considered to be the first autobiography of ever written in the canon of Western Literature. Augustine profoundly influenced the coming medieval worldview. The Summa Theologica, written 1265–1274, is the best-known work of Thomas Aquinas (c.1225–1274), and although unfinished, "one of the classics of the history of philosophy and one of the most influential works of Western literature." It is intended as a manual for beginners in theology and a compendium of all of the main theological teachings of the Church. It presents the reasoning for almost all points of Christian theology in the West. The epic poetry of the Italian Dante and his Divine Comedy of the late Middle Ages is also considered immensely influential. The English statesman and philosopher, Thomas More, wrote the seminal work Utopia in 1516. St Ignatius Loyola, a key figure in the Catholic counter-reformation, is the author of an influential book of meditations known as the Spiritual Exercises.
Christian philosophy is a term to describe the fusion of various fields of philosophy with the theological doctrines of Christianity. Scholasticism, which means "that [which] belongs to the school", and was a method of learning taught by the academics (or school people) of medieval universities c. 1100–1500. Scholasticism originally started to reconcile the philosophy of the ancient classical philosophers with medieval Christian theology. Scholasticism is not a philosophy or theology in itself but a tool and method for learning which places emphasis on dialectical reasoning.
Medieval philosophy is the philosophy of Western Europe and the Middle East during the Middle Ages, roughly extending from the Christianization of the Roman Empire until the Renaissance. Medieval philosophy is defined partly by the rediscovery and further development of classical Greek and Hellenistic philosophy, and partly by the need to address theological problems and to integrate the then widespread sacred doctrines of Abrahamic religion (Islam, Judaism, and Christianity) with secular learning.
The history of western European medieval philosophy is traditionally divided into two main periods: the period in the Latin West following the Early Middle Ages until the 12th century, when the works of Aristotle and Plato were preserved and cultivated; and the "golden age" of the 12th, 13th and 14th centuries in the Latin West, which witnessed the culmination of the recovery of ancient philosophy, and significant developments in the field of philosophy of religion, logic and metaphysics.
The medieval era was disparagingly treated by the Renaissance humanists, who saw it as a barbaric "middle" period between the classical age of Greek and Roman culture, and the "rebirth" or renaissance of classical culture. Yet this period of nearly a thousand years was the longest period of philosophical development in Europe, and possibly the richest. Jorge Gracia has argued that "in intensity, sophistication, and achievement, the philosophical flowering in the thirteenth century could be rightly said to rival the golden age of Greek philosophy in the fourth century B.C."
Some problems discussed throughout this period are the relation of faith to reason, the existence and unity of God, the object of theology and metaphysics, the problems of knowledge, of universals, and of individuation.
Philosophers from the Middle Ages include the Christian philosophers Augustine of Hippo, Boethius, Anselm, Gilbert of Poitiers, Peter Abelard, Roger Bacon, Bonaventure, Thomas Aquinas, Duns Scotus, William of Ockham and Jean Buridan; the Jewish philosophers Maimonides and Gersonides; and the Muslim philosophers Alkindus, Alfarabi, Alhazen, Avicenna, Algazel, Avempace, Abubacer, Ibn Khaldūn, and Averroes. The medieval tradition of Scholasticism continued to flourish as late as the 17th century, in figures such as Francisco Suarez and John of St. Thomas.
Aquinas, father of Thomism, was immensely influential in Catholic Europe, placed a great emphasis on reason and argumentation, and was one of the first to use the new translation of Aristotle's metaphysical and epistemological writing. His work was a significant departure from the Neoplatonic and Augustinian thinking that had dominated much of early Scholasticism.
The Renaissance ("rebirth") was a period of transition between the Middle Ages and modern thought, in which the recovery of classical texts helped shift philosophical interests away from technical studies in logic, metaphysics, and theology towards eclectic inquiries into morality, philology, and mysticism. The study of the classics and the humane arts generally, such as history and literature, enjoyed a scholarly interest hitherto unknown in Christendom, a tendency referred to as humanism. Displacing the medieval interest in metaphysics and logic, the humanists followed Petrarch in making man and his virtues the focus of philosophy.
These new movements in philosophy developed contemporaneously with larger religious and political transformations in Europe: the Reformation and the decline of feudalism. Though the theologians of the Protestant Reformation showed little direct interest in philosophy, their destruction of the traditional foundations of theological and intellectual authority harmonized with a revival of fideism and skepticism in thinkers such as Erasmus, Montaigne, and Francisco Sanches. Meanwhile, the gradual centralization of political power in nation-states was echoed by the emergence of secular political philosophies, as in the works of Niccolò Machiavelli (often described as the first modern political thinker, or a key turning point towards modern political thinking), Thomas More, Erasmus, Justus Lipsius, Jean Bodin, and Hugo Grotius.

Science and technology
Earlier attempts at reconciliation of Christianity with Newtonian mechanics appear quite different from later attempts at reconciliation with the newer scientific ideas of evolution or relativity. Many early interpretations of evolution polarized themselves around a struggle for existence. These ideas were significantly countered by later findings of universal patterns of biological cooperation. According to John Habgood, all man really knows here is that the universe seems to be a mix of good and evil, beauty and pain, and that suffering may somehow be part of the process of creation. Habgood holds that Christians should not be surprised that suffering may be used creatively by God, given their faith in the symbol of the Cross. Robert John Russell has examined consonance and dissonance between modern physics, evolutionary biology, and Christian theology.
Christian philosophers Augustine of Hippo (354–430) and Thomas Aquinas held that scriptures can have multiple interpretations on certain areas where the matters were far beyond their reach, therefore one should leave room for future findings to shed light on the meanings. The "Handmaiden" tradition, which saw secular studies of the universe as a very important and helpful part of arriving at a better understanding of scripture, was adopted throughout Christian history from early on. Also the sense that God created the world as a self operating system is what motivated many Christians throughout the Middle Ages to investigate nature.
Modern historians of science such as J.L. Heilbron, Alistair Cameron Crombie, David Lindberg, Edward Grant, Thomas Goldstein, and Ted Davis have reviewed the popular notion that medieval Christianity was a negative influence in the development of civilization and science. In their views, not only did the monks save and cultivate the remnants of ancient civilization during the barbarian invasions, but the medieval church promoted learning and science through its sponsorship of many universities which, under its leadership, grew rapidly in Europe in the 11th and 12th centuries, St. Thomas Aquinas, the Church's "model theologian", not only argued that reason is in harmony with faith, he even recognized that reason can contribute to understanding revelation, and so encouraged intellectual development. He was not unlike other medieval theologians who sought out reason in the effort to defend his faith. Some of today's scholars, such as Stanley Jaki, have claimed that Christianity with its particular worldview, was a crucial factor for the emergence of modern science.
Individual scientists' beliefs
Isaac Newton, for example, believed that gravity caused the planets to revolve about the Sun, and credited God with the design. In the concluding General Scholium to the Philosophiae Naturalis Principia Mathematica, he wrote: "This most beautiful System of the Sun, Planets and Comets, could only proceed from the counsel and dominion of an intelligent and powerful being." Other famous founders of science who adhered to Christian beliefs include Galileo, Johannes Kepler, and Blaise Pascal.
According to 100 Years of Nobel Prizes a review of Nobel prizes award between 1901 and 2000 reveals that (65.4%) of Nobel Prizes Laureates, have identified Christianity in its various forms as their religious preference.
Byzantine science was essentially classical science. Therefore, Byzantine science was in every period closely connected with ancient-pagan philosophy, and metaphysics. Despite some opposition to pagan learning, many of the most distinguished classical scholars held high office in the Church.  The writings of antiquity never ceased to be cultivated in the Byzantine empire due to the impetus given to classical studies by the Academy of Athens in the 4th and 5th centuries, the vigor of the philosophical academy of Alexandria, and to the services of the University of Constantinople, which concerned itself entirely with secular subjects, to the exclusion of theology, which was taught in the Patriarchical Academy. Even the latter offered instruction in the ancient classics, and included literary, philosophical, and scientific texts in its curriculum. The monastic schools concentrated upon the Bible, theology, and liturgy. Therefore, the monastic scriptoria expended most of their efforts upon the transcription of ecclesiastical manuscripts, while ancient-pagan literature was transcribed, summarized, excerpted, and annotated by laymen or clergy like Photios, Arethas of Caesarea, Eustathius of Thessalonica, and Basilius Bessarion. Byzantine scientists preserved and continued the legacy of the great Ancient Greek mathematicians and put mathematics in practice. In early Byzantium (5th to 7th century) the architects and mathematicians Isidore of Miletus and Anthemius of Tralles used complex mathematical formulas to construct the great Hagia Sophia church, a technological breakthrough for its time and for centuries afterwards due to its striking geometry, bold design and height. In late Byzantium (9th to 12th century) mathematicians like Michael Psellos considered mathematics as a way to interpret the world.
Middle Eastern Christians especially the adherents of the Church of the East (Nestorians), contributed to the Arab Islamic Civilization during the Ummayad and the Abbasid periods by translating works of Greek philosophers to Syriac and afterwards to Arabic. During the 4th through the 7th centuries, scholarly work in the Syriac and Greek languages was either newly initiated, or carried on from the Hellenistic period. Centers of learning and of transmission of classical wisdom included colleges such as the School of Nisibis, and later the School of Edessa, and the renowned hospital and medical academy of Jundishapur; libraries included the Library of Alexandria and the Imperial Library of Constantinople; other centers of translation and learning functioned at Merv, Salonika, Nishapur and Ctesiphon, situated just south of what later became Baghdad.
Many scholars of the House of Wisdom were of Christian background; the House of Wisdom was a library, translation institute, and academy established in Abbasid-era Baghdad, Iraq. Nestorians played a prominent role in the formation of Arab culture, with the Jundishapur school being prominent in the late Sassanid, Umayyad and early Abbasid periods. Notably, eight generations of the Nestorian Bukhtishu family served as private doctors to caliphs and sultans between the 8th and 11th centuries.
While refined and clarified over the centuries, the Roman Catholic position on the relationship between science and religion is one of harmony, and has maintained the teaching of natural law as set forth by Thomas Aquinas. For example, regarding scientific study such as that of evolution, the church's unofficial position is an example of theistic evolution, stating that faith and scientific findings regarding human evolution are not in conflict, though humans are regarded as a special creation, and that the existence of God is required to explain both monogenism and the spiritual component of human origins. Catholic schools have included all manners of scientific study in their curriculum for many centuries.
Galileo once stated "The intention of the Holy Spirit is to teach us how to go to heaven, not how the heavens go." In 1981 John Paul II, then pope of the Roman Catholic Church, spoke of the relationship this way: "The Bible itself speaks to us of the origin of the universe and its make-up, not in order to provide us with a scientific treatise, but in order to state the correct relationships of man with God and with the universe. Sacred Scripture wishes simply to declare that the world was created by God, and in order to teach this truth it expresses itself in the terms of the cosmology in use at the time of the writer".
The influence of the Church on Western letters and learning has been formidable. The ancient texts of the Bible have deeply influenced Western art, literature and culture. For centuries following the collapse of the Western Roman Empire, small monastic communities were practically the only outposts of literacy in Western Europe. In time, the Cathedral schools developed into Europe's earliest universities and the church has established thousands of primary, secondary and tertiary institutions throughout the world in the centuries since. The Church and clergymen have also sought at different times to censor texts and scholars. Thus different schools of opinion exist as to the role and influence of the Church in relation to western letters and learning.
One view, first propounded by Enlightenment philosophers, asserts that the Church's doctrines are entirely superstitious and have hindered the progress of civilization. Communist states have made similar arguments in their education in order to inculcate a negative view of Catholicism (and religion in general) in their citizens. The most famous incidents cited by such critics are the Church's condemnations of the teachings of Copernicus, Galileo Galilei and Johannes Kepler.
The Church's priest-scientists, many of whom were Jesuits, have been among the leading lights in astronomy, genetics, geomagnetism, meteorology, seismology, and solar physics, becoming some of the "fathers" of these sciences. Examples include important churchmen such as the Augustinian abbot Gregor Mendel (pioneer in the study of genetics), Roger Bacon (a Franciscan friar who was one of the early advocates of the scientific method), and Belgian priest Georges Lemaître (the first to propose the Big Bang theory). Other notable priest scientists have included Albertus Magnus, Robert Grosseteste, Nicholas Steno, Francesco Grimaldi, Giambattista Riccioli, Roger Boscovich, and Athanasius Kircher. Even more numerous are Catholic laity involved in science:Henri Becquerel who discovered radioactivity; Galvani, Volta, Ampere, Marconi, pioneers in electricity and telecommunications; Lavoisier, "father of modern chemistry"; Vesalius, founder of modern human anatomy; and Cauchy, one of the mathematicians who laid the rigorous foundations of calculus.
Throughout history many of the Roman Catholic clerics have made contributions to science, mostly during periods of Church domination of public life. These cleric-scientists include Nicolaus Copernicus, Gregor Mendel, Georges Lemaître, Albertus Magnus, Roger Bacon, Pierre Gassendi, Roger Joseph Boscovich, Marin Mersenne, Bernard Bolzano, Francesco Maria Grimaldi, Nicole Oresme, Jean Buridan, Robert Grosseteste, Christopher Clavius, Nicolas Steno, Athanasius Kircher, Giovanni Battista Riccioli, William of Ockham, and others. The Catholic Church has also produced many lay scientists and mathematicians, including 20th century Nobel Laureates like chemist Mario J. Molina, chemist John Polanyi, physicist Riccardo Giacconi, among many others.
Jesuit in science
The Jesuits have made numerous significant contributions to the development of science. For example, the Jesuits have dedicated significant study to earthquakes, and seismology has been described as "the Jesuit science". The Jesuits have been described as "the single most important contributor to experimental physics in the seventeenth century". According to Jonathan Wright in his book God's Soldiers, by the eighteenth century the Jesuits had "contributed to the development of pendulum clocks, pantographs, barometers, reflecting telescopes and microscopes, to scientific fields as various as magnetism, optics and electricity. They observed, in some cases before anyone else, the colored bands on Jupiter's surface, the Andromeda nebula and Saturn's rings. They theorized about the circulation of the blood (independently of Harvey), the theoretical possibility of flight, the way the moon affected the tides, and the wave-like nature of light."
Protestantism had an important influence on science. According to the Merton Thesis there was a positive correlation between the rise of Puritanism and Protestant Pietism on the one hand and early experimental science on the other. The Merton Thesis has two separate parts: Firstly, it presents a theory that science changes due to an accumulation of observations and improvement in experimental techniques and methodology; secondly, it puts forward the argument that the popularity of science in 17th-century England and the religious demography of the Royal Society (English scientists of that time were predominantly Puritans or other Protestants) can be explained by a correlation between Protestantism and the scientific values. In his theory, Robert K. Merton focused on English Puritanism and German Pietism as having been responsible for the development of the scientific revolution of the 17th and 18th centuries. Merton explained that the connection between religious affiliation and interest in science was the result of a significant synergy between the ascetic Protestant values and those of modern science. Protestant values encouraged scientific research by allowing science to study God's influence on the world and thus providing a religious justification for scientific research.
According of Scientific Elite: Nobel Laureates in the United State by Harriet Zuckerman, a review of American Nobel prizes winners awarded between 1901 and 1972, 72% of American Nobel Prize Laureates, have identified from Protestant background. Overall, Protestant have won a total of 84.2% of all the American Nobel Prizes in Chemistry, 60% in Medicine, 58.6% in Physics, between 1901 and 1972.
The university is generally regarded as an institution that has its origin in the Medieval Christian setting. Prior to the establishment of universities, European higher education took place for hundreds of years in Christian cathedral schools or monastic schools (Scholae monasticae), in which monks and nuns taught classes; evidence of these immediate forerunners of the later university at many places dates back to the 6th century AD.
Missionary activity for the Catholic Church has always incorporated education of evangelized peoples as part of its social ministry. History shows that in evangelized lands, the first people to operate schools were Roman Catholics. In some countries, the Church is the main provider of education or significantly supplements government forms of education. Presently, the Church operates the world's largest non-governmental school system. Many of Western Civilization's most influential universities were founded by the Catholic Church.
The Catholic Church founded the West's first universities, which were preceded by the schools attached to monasteries and cathedrals, and generally staffed by monks and friars. Universities began springing up in Italian towns like Salerno, which became a leading medical school, translating the work of Greek and Arabic physicians into Latin. Bologna University became the most influential of the early universities, which first specialised in canon law and civil law. Paris University, specialising in such topics as theology, came to rival Bologna under the supervision of Notre Dame Cathedral. Oxford University in England later came rival Paris in Theology and Salamanca University was founded in Spain in 1243. According to the historian Geoffrey Blainey, the universities benefitted from the use of Latin, the common language of the Church, and its internationalist reach, and their role was to "teach, argue and reason within a Christian framework". The medieval universities of Western Christendom were well-integrated across all of Western Europe, encouraged freedom of enquiry and produced a great variety of fine scholars and natural philosophers, including Robert Grosseteste of the University of Oxford, an early expositor of a systematic method of scientific experimentation; and Saint Albert the Great, a pioneer of biological field research
As the Reformers wanted all members of the church to be able to read the Bible, education on all levels got a strong boost. Compulsory education for both boys and girls was introduced. For example, the Puritans who established Massachusetts Bay Colony in 1628 founded Harvard College only eight years later. About a dozen other colleges followed in the 18th century, including Yale University (1701). Pennsylvania also became a centre of learning. While Princeton University was a Presbyterian foundation. Protestantism also initiated translations of the Bible into national languages and hereby supported the development of national literatures.
A large number of mainline Protestants have played leadership roles in many aspects of American life, including politics, business, science, the arts, and education. They founded most of the country's leading institutes of higher education. The Ivy League universities have strong White Anglo-Saxon Protestant historical ties, and their influence continues today. Until about World War II, Ivy League universities were composed largely of WASP students.
Some of the first colleges and universities in America, including Harvard, Yale, Princeton, Columbia, Dartmouth, Williams, Bowdoin, Middlebury, and Amherst, all were founded by the Mainline Protestantism, as were later Carleton, Duke, Oberlin, Beloit, Pomona, Rollins and Colorado College.
According to Pew Center study there is correlation between education and income, about (59%) of American Anglican have a graduate and post-graduate degree, and about (56%) of Episcopalians and (47%) of Presbyterians and (46%) United Church of Christ, have a graduate and post-graduate degree.
A Pew Center study about religion and education around the world in 2016, found that Christians ranked as the second most educated religious group around in the world after Jews with an average of 9.3 years of schooling, and the highest of years of schooling among Christians found in Germany (13.6), New Zealand (13.5) and Estonia (13.1). Christians were also found to have the second highest number of graduate and post-graduate degrees per capita while in absolute numbers ranked in the first place (220 million). Between the various Christian communities, Singapore outranks other nations in terms of Christians who obtain a university degree in institutions of higher education (67%), followed by the Christians of Israel (63%), and the Christians of Georgia (57%). According to the study, Christians in North America, Europe, Middle East, North Africa and Asia-Pacific regions are highly educated since many of the world universities were built by the historic Christian Churches, in addition to the historical evidence that "Christian monks built libraries and, in the days before printing presses, preserved important earlier writings produced in Latin, Greek and Arabic". According to the same study, Christians have a significant amount of gender equality in educational attainment, and the study suggests that one of the reasons is the encouragement of the Protestant Reformers in promoting the education of women, which led to the eradication of illiteracy among females in Protestant communities. According to the same study "there is a large and pervasive gap in educational attainment between Muslims and Christians in sub-Saharan Africa" as Muslim adults in this region are far less educated than their Christian counterparts, with scholars suggesting that this gap is due to the educational facilities that were created by Christian missionaries during the colonial era for fellow believers.
Medicine and health care
The administration of the Eastern and Western Roman Empires split and the demise of the Western Empire by the sixth century was accompanied by a series of violent invasions and precipitated the collapse of cities and civic institutions of learning, along with their links to the learning of classical Greece and Rome. For the next thousand years, medical knowledge would change very little. A scholarly medical tradition maintained itself in the more stable East, but in the West, scholarship virtually disappeared outside of the Church, where monks were aware of a dwindling range of medical texts. Hospitality was considered an obligation of Christian charity and bishops' houses and the valetudinaria of wealthier Christians were used to tend the sick. And the legacy of this early period was, in the words of Porter, that "Christianity planted the hospital: the well-endowed establishments of the Levant and the scattered houses of the West shared a common religious ethos of charity."
The Byzantine Empire was one of the first empires to have flourishing medical establishments. Prior to the Byzantine Empire the Roman Empire had hospitals specifically for soldiers and slaves. However, none of these establishments were for the public. The hospitals in Byzantium were originally started by the church to act as a place for the poor to have access to basic amenities. Hospitals were usually separated between men and women. Although the remains of these hospitals have not been discovered by archaeologists, recordings of hospitals from the Byzantine Empire describe large buildings that had the core feature of an open hearth. The establishments of the Byzantine Empire resembled the beginning of what we now know as modern hospitals. The first hospital was erected by Leontius of Antioch between the years 344 to 358 and was a place for strangers and migrants to find refuge. Around the same time, a deacon named Marathonius was in charge of hospitals and monasteries in Constantinople. His main objective was to improve urban aesthetics, illustrating hospitals as a main part of Byzantine cities. These early hospitals were designed for the poor. In fact, most hospitals throughout the Byzantine Empire were almost exclusively utilized by the poor. This may be due to descriptions of hospitals similar to "Gregory Nazianzen who called the hospital a stairway to heaven, implying that it aimed only to ease death for the chronically or terminally ill rather than promote recovery". There is debate between scholars as to why these institutions were started by the church. Many scholars believe that the church founded hospitals in order to receive additional donations. Whatever the case for these hospitals, they began to diffuse across the empire. Soon after, St. Basil of Caesarea developed a place for the sick in which provided refuge for the sick and homeless.
Geoffrey Blainey likened the Catholic Church in its activities during the Middle Ages to an early version of a welfare state: "It conducted hospitals for the old and orphanages for the young; hospices for the sick of all ages; places for the lepers; and hostels or inns where pilgrims could buy a cheap bed and meal". It supplied food to the population during famine and distributed food to the poor. This welfare system the church funded through collecting taxes on a large scale and possessing large farmlands and estates. It was common for monks and clerics to practice medicine and medical students in northern European universities often took minor Holy orders. Mediaeval hospitals had a strongly Christian ethos, and were, in the words of historian of medicine Roy Porter, "religious foundations through and through", and Ecclesiastical regulations were passed to govern medicine, partly to prevent clergymen profiting from medicine. During Europe's Age of Discovery, Catholic missionaries, notably the Jesuits, introduced the modern sciences to India, China and Japan. While persecutions continue to limit the spread of Catholic institutions to some Middle Eastern Muslim nations, and such places as the People's Republic of China and North Korea, elsewhere in Asia the church is a major provider of health care services - especially in Catholic Nations like the Philippines.
Today the Roman Catholic Church is the largest non-government provider of health care services in the world. It has around 18,000 clinics, 16,000 homes for the elderly and those with special needs, and 5,500 hospitals, with 65 percent of them located in developing countries. In 2010, the Church's Pontifical Council for the Pastoral Care of Health Care Workers said that the Church manages 26% of the world's health care facilities. The Church's involvement in health care has ancient origins.
Thought and work ethic
Francisco de Vitoria, a disciple of Thomas Aquinas and a Catholic thinker who studied the issue regarding the human rights of colonized natives, is recognized by the United Nations as a father of international law, and now also by historians of economics and democracy as a leading light for the West's democracy and rapid economic development. Joseph Schumpeter, an economist of the twentieth century, referring to the Scholastics, wrote, "it is they who come nearer than does any other group to having been the 'founders' of scientific economics." Other economists and historians, such as Raymond de Roover, Marjorie Grice-Hutchinson, and Alejandro Chafuen, have also made similar statements.
The Protestant concept of God and man allows believers to use all their God-given faculties, including the power of reason. That means that they are allowed to explore God's creation and, according to Genesis 2:15, make use of it in a responsible and sustainable way. Thus a cultural climate was created that greatly enhanced the development of the humanities and the sciences. Another consequence of the Protestant understanding of man is that the believers, in gratitude for their election and redemption in Christ, are to follow God's commandments. Industry, frugality, calling, discipline, and a strong sense of responsibility are at the heart of their moral code. In particular, John Calvin rejected luxury. Therefore, craftsmen, industrialists, and other businessmen were able to reinvest the greater part of their profits in the most efficient machinery and the most modern production methods that were based on progress in the sciences and technology. As a result, productivity grew, which led to increased profits and enabled employers to pay higher wages. In this way, the economy, the sciences, and technology reinforced each other. The chance to participate in the economic success of technological inventions was a strong incentive to both inventors and investors. The Protestant work ethic was an important force behind the unplanned and uncoordinated mass action that influenced the development of capitalism and the industrial revolution. This idea is also known as the "Protestant ethic thesis." In the book The Central Liberal Truth: How Politics Can Change a Culture and Save It from Itself Lawrence E. Harrison argues that Protestantism along with Confucianism, and Judaism have been more successful in promoting progress, culture and society. Due to the Protestant virtues of education, achievement, work ethic, merit, frugality, and honesty.
Some mainline Protestant denominations such as Episcopalians and Presbyterians and congregationalist tend to be considerably wealthier and better educated (having high proportion of graduate and post-graduate degrees per capita) than most other religious groups in America, and are disproportionately represented in the upper reaches of American business, law and politics, especially the Republican Party. Large numbers of the most wealthy and affluent American families as the Vanderbilts and Astors, Rockefeller, Du Pont, Roosevelt, Forbes, Whitneys, the Morgans and Harrimans are Mainline Protestant families.
Roman Catholics, Anglicans, Eastern Christians, and traditional Protestant communities frame worship around the liturgical year. The liturgical cycle divides the year into a series of seasons, each with their theological emphases, and modes of prayer, which can be signified by different ways of decorating churches, colours of paraments and vestments for clergy, scriptural readings, themes for preaching and even different traditions and practices often observed personally or in the home.
Western Christian liturgical calendars are based on the cycle of the Roman Rite of the Catholic Church, and Eastern Christians use analogous calendars based on the cycle of their respective rites. Calendars set aside holy days, such as solemnities which commemorate an event in the life of Jesus or Mary, the saints, periods of fasting such as Lent, and other pious events such as memoria or lesser festivals commemorating saints. Christian groups that do not follow a liturgical tradition often retain certain celebrations, such as Christmas, Easter and Pentecost: these are the celebrations of Christ's birth, resurrection and the descent of the Holy Spirit upon the Church, respectively. A few denominations make no use of a liturgical calendar.
Roman Catholic theology enumerates seven sacraments: Baptism (Christening), Confirmation (Chrismation), Eucharist (Communion), Penance (Reconciliation), Anointing of the Sick (before the Second Vatican Council generally called Extreme Unction), Matrimony
In Christian belief and practice, a sacrament is a rite, instituted by Christ, that mediates grace, constituting a sacred mystery. The term is derived from the Latin word sacramentum, which was used to translate the Greek word for mystery. Views concerning both what rites are sacramental, and what it means for an act to be a sacrament vary among Christian denominations and traditions.
The most conventional functional definition of a sacrament is that it is an outward sign, instituted by Christ, that conveys an inward, spiritual grace through Christ. The two most widely accepted sacraments are Baptism and the Eucharist (or Holy Communion), however, the majority of Christians also recognize five additional sacraments: Confirmation (Chrismation in the Orthodox tradition), Holy orders (ordination), Penance (or Confession), Anointing of the Sick, and Matrimony (see Christian views on marriage).
Taken together, these are the Seven Sacraments as recognized by churches in the High Church tradition—notably Roman Catholic, Eastern Orthodox, Oriental Orthodox, Independent Catholic, Old Catholic, many Anglicans, and some Lutherans. Most other denominations and traditions typically affirm only Baptism and Eucharist as sacraments, while some Protestant groups, such as the Quakers, reject sacramental theology. Christian denominations, such as Baptists, which believe these rites do not communicate grace, prefer to call Baptism and Holy Communion ordinances rather than sacraments.
Today, most Christian denominations are neutral about religious male circumcision, neither requiring it nor forbidding it. The practice is customary among the Coptic, Ethiopian, and Eritrean Orthodox Churches, and also some other African churches.
Worship can be varied for special events like baptisms or weddings in the service or significant feast days. In the early church, Christians and those yet to complete initiation would separate for the Eucharistic part of the worship. In many churches today, adults and children will separate for all or some of the service to receive age-appropriate teaching. Such children's worship is often called Sunday school or Sabbath school (Sunday schools are often held before rather than during services).
In mainstream Nicene Christianity, there is no restriction on kinds of animals that can be eaten. This practice stems from Peter's vision of a sheet with animals, in which Saint Peter "sees a sheet containing animals of every description lowered from the sky." Nonetheless, the New Testament does give a few guidelines about the consumption of meat, practiced by the Christian Church today; one of these is not consuming food knowingly offered to pagan idols, a conviction that the early Church Fathers, such as Clement of Alexandria and Origen preached. In addition, Christians traditionally bless any food before eating it with a mealtime prayer (grace), as a sign of thanking God for the meal they have.
Slaughtering animals for food is often done without the trinitarian formula, although the Armenian Apostolic Church, among other Orthodox Christians, have rituals that "display obvious links with shechitah, Jewish kosher slaughter." The Bible states Norman Geisler, stipulates one to "abstain from food sacrificed to idols, from blood, from meat of strangled animals". In the New Testament, Paul of Tarsus notes that some devout Christians may wish to abstain from consuming meat if it causes "my brother to stumble" in his faith with God. As such, some Christian monks, such as the Trappists, have adopted a policy of Christian vegetarianism. In addition, Christians of the Seventh-day Adventist tradition generally "avoid eating meat and highly spiced food". Christians in the Anglican, Catholic, Lutheran, Methodist, and Orthodox denominations traditionally observe a meat-free day, especially during the liturgical season of Lent.
Some Christian denominations condone the moderate drinking of alcohol (moderationism), such as Anglicans, Catholics, Lutherans, and the Orthodox, although others, such as Adventists, Baptists, Methodists, and Pentecostals either abstain from or prohibit the consumption of alcohol (abstentionism and prohibitionism). However, all Christian Churches, in view of the Biblical position on the issue, universally condemn drunkenness as sinful.
Christian cooking combines the food of many cultures in which Christian have lived. A special Christmas family meal is traditionally an important part of the holiday's celebration, and the food that is served varies greatly from country to country. Some regions, such as Sicily, have special meals for Christmas Eve, when 12 kinds of fish are served. In the United Kingdom and countries influenced by its traditions, a standard Christmas meal includes turkey, goose or other large bird, gravy, potatoes, vegetables, sometimes bread and cider. Special desserts are also prepared, such as Christmas pudding, mince pies, fruit cake and Yule log.
The Bible has many rituals of purification relating to menstruation, childbirth, sexual relations, nocturnal emission, unusual bodily fluids, skin disease, death, and animal sacrifices. The Ethiopian Orthodox Tewahedo Church prescribes several kinds of hand washing for example after leaving the latrine, lavatory or bathhouse, or before prayer, or after eating a meal. The women in the Ethiopian Orthodox Tewahedo Church are prohibited from entering the church temple during menses; and the men do not enter a church the day after they have had intercourse with their wives.
Christianity has always placed a strong emphasis on hygiene, Despite the denunciation of the mixed bathing style of Roman pools by early Christian clergy, as well as the pagan custom of women naked bathing in front of men, this did not stop the Church from urging its followers to go to public baths for bathing, which contributed to hygiene and good health according to the Church Father, Clement of Alexandria. The Church also built public bathing facilities that were separate for both sexes near monasteries and pilgrimage sites; also, the popes situated baths within church basilicas and monasteries since the early Middle Ages. Pope Gregory the Great urged his followers on value of bathing as a bodily need.
Contrary to popular belief bathing and sanitation were not lost in Europe with the collapse of the Roman Empire. Soapmaking first became an established trade during the so-called "Dark Ages". The Romans used scented oils (mostly from Egypt), among other alternatives. By the mid-19th century, the English urbanised middle classes had formed an ideology of cleanliness that ranked alongside typical Victorian concepts, such as Christianity, respectability and social progress. The Salvation Army has adopted movement of the deployment of the personal hygiene, and by providing personal hygiene products.

- Frederick Copleston, A History of Philosophy, Volume II: From Augustine to Scotus (Burns & Oates, 1950), p. 1, dates medieval philosophy proper from the Carolingian Renaissance in the eighth century to the end of the fourteenth century, though he includes Augustine and the Patristic fathers as precursors. Desmond Henry, in Paul Edwards (ed.), The Encyclopedia of Philosophy (Macmillan, 1967), vol. 5, pp. 252–257, starts with Augustine and ends with Nicholas of Oresme in the late fourteenth century.

In the meantime, Peter in Joppa has a middday vision in which he sees a sheet containing animals of every description lowered from the sky. He hears a voice from heaven telling him to "kill and eat." Peter is naturally taken aback, because eating some of these animals would mean breaking the Jewish rules about kosher foods. But then he hears a voice that tells him, "What God has cleansed, you must not call common [unclean]" (that is, you do not need to refrain from eating nonkosher foods; 10: 15). The same sequence of events happens three times.

Christ came for the Gentiles as well as the Jews (the real meaning of that vision in Acts 10:9;16) but he also calls us to look out for each other and not do things that will cause our brothers and sisters to stumble. In Corinthians Paul urges the believers to consider not eating meat when with people who assume that meat must be offered to idols before consumption: 'Food will not bring us close to God,' he writes. 'We are no worse off if we do not eat, and no better off if we do. But take care that this liberty of yours does not somehow become a stumbling block for the weak.' (1 Corinthians 8:8–9)

Clement of Alexandria and Origen also forbid eating meat dedicated to idolatry and partaking in meals with demons, which, by association, are the meals of fornicators and idolatrous adulterers. Marcianus Aristides merely testifies that Christians do not eat what has been sacrificed to idols; and Hippolytus only notes the interdiction against eating such food.

Later, laws were instituted that declared certain meats to be "clean" and others to be "unclean." The system provided a means of proving one's obedience to God and had some health benefits. After Jesus Christ came, God declared all meats to be clean. Current slaughterhouse practices comply with the dictate to remove the blood, so virtually all meat today is acceptable to eat according to God.

Nevertheless, toward the end of the chapter, Paul suggests that even Christians with strong faith may want to abstain from eating meat offered to pagan deities if any chance that their example will tempt fellow Christians of weaker faith into inadvertent idolatry. He concludes by saying, "Therefore, if food causes my brother to stumble, I will never eat meat again, so that I will not cause my brother to stumble." (1 Corinthians 8:13)

The main legally enforced prohibition in both Catholic and Anglican countries was that against meat. During Lent, the most prominent annual season of fasting in Catholic and Anglican churches, authorities enjoined abstinence from meat and sometimes "white meats" (cheese, milk, and eggs); in sixteenth- and seventeenth-century England butchers and victuallers were bound by heavy recognizances not to slaughter or sell meat on the weekly "fish days," Friday and Saturday.
