Since the publication of Charles Darwin's On the Origin of Species in 1859, the attitude of the Catholic Church on the theory of evolution has slowly been refined. Early contributions to the development of evolutionary theory were made by Catholic scientists such as Jean-Baptiste Lamarck and the Augustinian monk Gregor Mendel. For nearly a century, the papacy offered no authoritative pronouncement on Darwin's theories. In the 1950 encyclical Humani generis, Pope Pius XII confirmed that there is no intrinsic conflict between Christianity and the theory of evolution, provided that Christians believe that the individual soul is a direct creation by God and not the product of purely material forces. Today[update], the Church supports theistic evolution(ism), also known as evolutionary creation, although Catholics are free not to believe in any part of evolutionary theory.
The Catholic Church holds no official position on the theory of creation or evolution, leaving the specifics of either theistic evolution or literal creationism to the individual within certain parameters established by the Church. According to the Catechism of the Catholic Church, any believer may accept either literal or special creation within the period of an actual six day, twenty-four hour period, or they may accept the belief that the earth evolved over time under the guidance of God. Catholicism holds that God initiated and continued the process of his evolutionary creation, that Adam and Eve were real people (the Church rejects polygenism) and affirms that all humans, whether specially created or evolved, have and have always had specially created souls for each individual.
Catholic schools in the United States and other countries teach evolution as part of their science curriculum. They teach the fact that evolution occurs and the modern evolutionary synthesis, which is the scientific theory that explains why evolution occurs. This is the same evolution curriculum that secular schools teach. Bishop Francis X. DiLorenzo of Richmond, chair of the Committee on Science and Human Values, wrote in a letter sent to all U.S. bishops in December 2004: "... Catholic schools should continue teaching evolution as a scientific theory backed by convincing evidence. At the same time, Catholic parents whose children are in public schools should ensure that their children are also receiving appropriate catechesis at home and in the parish on God as Creator. Students should be able to leave their biology classes, and their courses in religious instruction, with an integrated understanding of the means God chose to make us who we are."

Early contributions to evolutionary theory
Among Catholic contributors to the development of evolutionary theory were, the Jesuit educated French scientist Jean-Baptiste Lamarck (1744-1829) and the Augustinian monk Gregor Mendel (1822-1884). Lamarck developed Lamarckism, the first coherent theory of evolution, proposing in Philosophie Zoologique (1809) and other works his theory of the transmutation of species and drawing a genealogical tree to show the genetic connection of organisms.
Mendel joined the Brno Augustinian Monastery in 1843, but also trained as a scientist at the Olmutz Philosophical Institute and the University of Vienna. The Brno Monastery was a centre of scholarship, with an extensive library and tradition of scientific research. At the monastery, Mendel discovered the basis of genetics following long study of the inherited characteristics of pea plants, although his paper Experiments on Plant Hybridization, published in 1866, was largely overlooked until the start of the next century. He developed mathematical formulae to explain the occurrence, and confirmed the results in other plants. Where Darwin's theories suggested a mechanism for improvement of species over generations, Mendel's observations provided explanation for how a new species itself could emerge. Though Darwin and Mendel never collaborated, they were aware of each other's work (Darwin read a paper by Wilhelm Olbers Focke which extensively referenced Mendel). Bill Bryson wrote that "without realizing it, Darwin and Mendel laid the groundwork for all of life sciences in the twentieth century. Darwin saw that all living things are connected, that ultimately they trace their ancestry to a single, common source; Mendel's work provided the mechanism to explain how that could happen". Biologist J. B. S. Haldane and others brought together the principles of Mendelian inheritance with Darwinian principles of evolution to form the field of genetics known as Modern evolutionary synthesis.
Changing awareness of the age of the earth and fossil records helped in the development of evolutionary theory. The work of the Danish Bishop Nicolas Steno (1638-1686) helped establish the science of geology, leading to modern scientific measurements of the age of the earth.
Early reaction to Darwin
Catholic concern about evolution has always been very largely concerned with the implications of evolutionary theory for the origin of the human species; even by 1859, a literal reading of the Book of Genesis had long been undermined by developments in geology and other fields. No high-level Church pronouncement has ever attacked head-on the theory of evolution as applied to non-human species.
Even before the development of modern scientific method, Catholic theology had allowed for biblical text to be read as allegorical, rather than literal, where it appeared to contradict that which could be established by science or reason. Thus Catholicism has been able to refine its understanding of scripture in light of scientific discovery. Among the early Church Fathers there was debate over whether God created the world in six days, as Clement of Alexandria taught, or in a single moment as held by Augustine, and a literal interpretation of Genesis was normally taken for granted in the Middle Ages and later, until it was rejected in favour of uniformitarianism (entailing far greater timeframes) by a majority of geologists in the 19th century. However modern literal creationism has had little support among the higher levels of the Church.
The Catholic Church delayed official pronouncements on Darwin's Origin of Species for many decades. While many hostile comments were made by local clergy, Origin of Species was never placed on the Index Librorum Prohibitorum; in contrast, Henri Bergson's non-Darwinian Creative Evolution (1907), was on the Index from 1948 until it was abolished in 1966. However, a number of Catholic writers who published works specifying how evolutionary theory and Catholic theology might be reconciled ran into trouble of some sort with the Vatican authorities. According to the historian of science and theologian Barry Brundell: "Theologians and historians of science have always been struck by the seemingly enigmatic response of Rome when it did come; the authorities were obviously unhappy with the propagation of 'Christianized evolution', but it seems they were not willing or able to say so straight out and in public". H.L. Mencken observed that:
[The advantage of Catholics] lies in the simple fact that they do not have to decide either for Evolution or against it. Authority has not spoken on the subject; hence it puts no burden upon conscience, and may be discussed realistically and without prejudice. A certain wariness, of course, is necessary. I say that authority has not spoken; it may, however, speak tomorrow, and so the prudent man remembers his step. But in the meanwhile there is nothing to prevent him examining all available facts, and even offering arguments in support of them or against them—so long as those arguments are not presented as dogma.
19th century reception among Catholics
The first notable statement after Darwin published his theory appeared in 1860 from a council of the German bishops, who pronounced:
"Our first parents were formed immediately by God. Therefore we declare that the opinion of those who do not fear to assert that this human being, man as regards his body, emerged finally from the spontaneous continuous change of imperfect nature to the more perfect, is clearly opposed to Sacred Scripture and to the Faith."
No Vatican response was made to this, which some have taken to imply agreement. No mention of evolution was made in the pronouncements of the First Vatican Council in 1868. In the following decades, a consistently and aggressively anti-evolution position was taken by the influential Jesuit periodical La Civiltà Cattolica, which, though unofficial, was generally believed to have accurate information about the views and actions of the Vatican authorities. The opening in 1998 of the Archive of the Congregation for the Doctrine of the Faith (in the 19th century called the Holy Office and the Congregation of the Index) has revealed that on many crucial points this belief was mistaken, and the journal's accounts of specific cases, often the only ones made public, were not accurate. The original documents show the Vatican's attitude was much less fixed than appeared to be the case at the time.
As to the Divine Design, is it not an instance of incomprehensibly and infinitely marvellous Wisdom and Design to have given certain laws to matter millions of ages ago, which have surely and precisely worked out, in the long course of those ages, those effects which He from the first proposed. Mr. Darwin's theory need not then to be atheistical, be it true or not; it may simply be suggesting a larger idea of Divine Prescience and Skill. Perhaps your friend has got a surer clue to guide him than I have, who have never studied the question, and I do not [see] that 'the accidental evolution of organic beings' is inconsistent with divine design—It is accidental to us, not to God.
In 1894 a letter was received by the Holy Office, asking for confirmation of the Church's position on a theological book of generally Darwinist cast by a French Dominican theologian, L'évolution restreinte aux espèces organiques, par le père Léroy dominicain. The records of the Holy Office document lengthy debates, with a number of experts consulted, whose views varied considerably. In 1895 the Congregation decided against the book, and Fr. Léroy was summoned to Rome, where it was explained that his views were unacceptable, and he agreed to withdraw the book. No decree was issued against Léroy's book, and consequently, the book was never placed on the Index. Again, the concerns of the experts had concentrated entirely on human evolution.
To reconcile general evolutionary theory with the origin of the human species, with a soul, the concept of "special transformism" was developed, according to which the first humans had evolved by Darwinist processes, up to the point where a soul was added by God to "pre-existent and living matter" (in the words of Pius XII's Humani Generis) to form the first fully human individuals; this would normally be considered to be at the point of conception. Léroy's book endorsed this concept; what led to its rejection by the Congregation appears to have been his view that the human species was able to evolve without divine intervention to a fully human state, but lacking only a soul. The theologians felt that some immediate and particular divine intervention was also required to form the physical nature of humans, before the addition of a soul, even if this was worked on near-human hominids produced by evolutionary processes.
The following year, 1896, John Augustine Zahm, a well-known American Holy Cross priest who had been a professor of physics and chemistry at the Catholic University of Notre Dame, Indiana, and was then Procurator General of his Order in Rome, published Evolution and Dogma, arguing that Church teaching, the Bible, and evolution did not conflict. The book was denounced to the Congregation of the Index, who decided to condemn the book but did not publish the corresponding decree, and consequently, the book was never included on the Index. Zahm, who had returned to the United States as Provincial superior of his Order, wrote to his French and Italian editors in 1899, asking them to withdraw the book from the market; however, he never recanted his views. In the meantime his book (in an Italian translation with the imprimatur of Siena) had had a great impact on Geremia Bonomelli, the Bishop of Cremona in Italy, who added an appendix to a book of his own, summarizing and recommending Zahn's views. Bonomelli too was pressured, and retracted his views in a public letter, also in 1898.
Zahm, like St. George Jackson Mivart and his followers, accepted evolution, but not the key Darwinist principle of natural selection, which was still a common position among biologists in general at the time. Another American Catholic author William Seton accepted natural selection also, and was a prolific advocate in the Catholic and general press.
Pope Pius IX
On the Origin of Species was published in 1859, during the papacy of Pope Pius IX, who defined dogmatically papal infallibility during the First Vatican Council in 1869–70. The council has a section on "Faith and Reason" that includes the following on science and faith:
- "9. Hence all faithful Christians are forbidden to defend as the legitimate conclusions of science those opinions which are known to be contrary to the doctrine of faith, particularly if they have been condemned by the Church; and furthermore they are absolutely bound to hold them to be errors which wear the deceptive appearance of truth." (Vatican Council I)
- "10. Not only can faith and reason never be at odds with one another but they mutually support each other, for on the one hand right reason established the foundations of the faith and, illuminated by its light, develops the science of divine things; on the other hand, faith delivers reason from errors and protects it and furnishes it with knowledge of many kinds." (Vatican Council I)
On God the Creator, the Vatican Council was very clear. The definitions preceding the "anathema" (as a technical term of Catholic theology, let him be "cut off" or excommunicated, cf. Galatians 1:6–9; Titus 3:10–11; Matthew 18:15–17) signify an infallible doctrine of the Catholic Faith (De Fide):
- On God the creator of all things
- If anyone denies the one true God, creator and lord of things visible and invisible: let him be anathema.
- If anyone is so bold as to assert that there exists nothing besides matter: let him be anathema.
- If anyone says that the substance or essence of God and that of all things are one and the same: let him be anathema.
- If anyone says that finite things, both corporal and spiritual, or at any rate, spiritual, emanated from the divine substance; or that the divine essence, by the manifestation and evolution of itself becomes all things or, finally, that God is a universal or indefinite being which by self-determination establishes the totality of things distinct in genera, species and individuals: let him be anathema.
- If anyone does not confess that the world and all things which are contained in it, both spiritual and material, were produced, according to their whole substance, out of nothing by God; or holds that God did not create by his will free from all necessity, but as necessarily as he necessarily loves himself; or denies that the world was created for the glory of God: let him be anathema.
According to Catholic theologian Dr. Ludwig Ott in his 1952 treatise Fundamentals of Catholic Dogma, it is to be understood that these condemnations are of the errors of modern materialism (that matter is all there is), pantheism (that God and the universe are identical), and ancient pagan and gnostic-manichean dualism (where God is not responsible for the entire created world, since mere "matter" is evil not good, see Ott, page 79).
The First Vatican Council also upholds the ability of reason to know God from his creation:
- "1. The same Holy mother Church holds and teaches that God, the source and end of all things, can be known with certainty from the consideration of created things, by the natural power of human reason: ever since the creation of the world, his invisible nature has been clearly perceived in the things that have been made." (Chapter 2, On Revelation; cf. Romans 1:19–20; and Wisdom chapter 13)
Popes Leo XIII and Pius X
Pope Leo XIII, who succeeded in 1878, was known to advocate a more open approach to science, but also to be frustrated by opposition to this within the Vatican and leading church circles, "lamenting on a number of occasions, and not in a particularly private way, the repressive attitudes to scholars exhibited by people around him, and among those he clearly included members of the Civiltà Cattolica college of writers". On one occasion there was "quite a scene when the Pope energetically refused to have the writings of Mons. D'Hulst of Paris put on the Index of Forbidden Books".
Providentissimus Deus, "On the Study of Holy Scripture", was an encyclical issued by Leo XIII on 18 November 1893 on the interpretation of Scripture. It was intended to address the issues arising from both the "higher criticism" and new scientific theories, and their relation with Scripture. Nothing specific concerning evolution was said, and initially both those in favour and against evolution found things to encourage them in the text; however a more conservative interpretation came to be dominant, and the influence of the conservative Jesuit Cardinal Camillo Mazzella (with whom Leo had argued over Mons. D'Hulst) detected. Leo stressed the unstable and changing nature of scientific theory, and criticised the "thirst for novelty and the unrestrained freedom of thought" of the age, but accepted that the apparent literal sense of the Bible might not always be correct. In biblical interpretation, Catholic scholars should not "depart from the literal and obvious sense, except only where reason makes it untenable or necessity requires". Leo stressed that both theologians and scientists should confine themselves to their own disciplines as much as possible.
An earlier encyclical of Leo's on marriage, Arcanum Divinae Sapientiae (1880) had described in passing the Genesis account of the creation of Eve from Adam's side as "what is to all known, and cannot be doubted by any ..."
The Pontifical Biblical Commission issued a decree ratified by Pope Pius X on June 30, 1909 that stated that the literal historical meaning of the first chapters of Genesis could not be doubted in regard to "the creation of all things by God at the beginning of time; the special creation of man; the formation of the first woman from the first man; the unity of the human race....". As in 1860, "special creation" was only referred to in respect of the human species.
Pope Pius XII
- "The Church does not forbid that ... research and discussions, on the part of men experienced in both fields, take place with regard to the doctrine of evolution, in as far as it inquires into the origin of the human body as coming from pre-existent and living matter."
Pope Pius XII's teaching can be summarized as follows:
- The question of the origin of man's body from pre-existing and living matter is a legitimate matter of inquiry for natural science. Catholics are free to form their own opinions, but they should do so cautiously; they should not confuse fact with conjecture, and they should respect the Church's right to define matters touching on Revelation.
- Catholics must believe, however, that humans have souls created immediately by God. Since the soul is a spiritual substance it is not brought into being through transformation of matter, but directly by God, whence the special uniqueness of each person.
- All men have descended from an individual, Adam, who has transmitted original sin to all mankind. Catholics may not, therefore, believe in "polygenism", the scientific hypothesis that mankind descended from a group of original humans (that there were many Adams and Eves).
Some theologians believe Pius XII explicitly excludes belief in polygenism as licit. The relevant sentence is this:
- "Now it is in no way apparent how such an opinion (polygenism) can be reconciled with that which the sources of revealed truth and the documents of the Teaching Authority of the Church propose with regard to original sin, which proceeds from a sin actually committed by an individual Adam and which, through generation, is passed on to all and is in everyone as his own." (Pius XII, Humani Generis, 37 and footnote refers to Romans 5:12–19; Council of Trent, Session V, Canons 1–4)
Pope John Paul II
- "In his encyclical Humani Generis (1950), my predecessor Pius XII has already affirmed that there is no conflict between evolution and the doctrine of the faith regarding man and his vocation, provided that we do not lose sight of certain fixed points.... Today, more than a half-century after the appearance of that encyclical, some new findings lead us toward the recognition of evolution as more than a hypothesis. In fact it is remarkable that this theory has had progressively greater influence on the spirit of researchers, following a series of discoveries in different scholarly disciplines. The convergence in the results of these independent studies—which was neither planned nor sought—constitutes in itself a significant argument in favor of the theory."
In the same address, Pope John Paul II rejected any theory of evolution that provides a materialistic explanation for the human soul:
- "Theories of evolution which, because of the philosophies which inspire them, regard the spirit either as emerging from the forces of living matter, or as a simple epiphenomenon of that matter, are incompatible with the truth about man."
Pope Benedict XVI
Statements by Cardinal Christoph Schönborn, a close colleague of Benedict XVI, especially a piece in The New York Times on July 7, 2005, appeared to support Intelligent Design, giving rise to speculation about a new direction in the Church's stance on the compatibility between evolution and Catholic dogma; many of Schönborn's complaints about Darwinian evolution echoed pronouncements originating from the Discovery Institute, an interdenominational Christian think tank. However, Cardinal Schönborn's book Chance or Purpose (2007, originally in German) accepted with certain qualifications the "scientific theory of evolution", but attacked "evolutionism as an ideology", which he said sought to displace religious teaching over a wide range of issues. Nonetheless, in the mid-1980s, Pope Benedict XVI, while serving as Prefect of the Sacred Congregation of the Doctrine of the Faith, wrote a defense of the doctrine of creation against Catholics who stressed the sufficiency of "selection and mutation". Humans, he insisted, are "not the products of chance and error", and "the universe is not the product of darkness and unreason; it comes from intelligence, freedom, and from the beauty that is identical with love."
A five-day conference, Biological Evolution: Facts and Theories, held in March 2009 by the Pontifical University in Rome, marking the 150th anniversary of the publication of the Origin of Species, generally confirmed the lack of conflict between evolutionary theory and Catholic theology, and the rejection of Intelligent Design by Catholic scholars.
The Church has deferred to scientists on matters such as the age of the earth and the authenticity of the fossil record. Papal pronouncements, along with commentaries by cardinals, have accepted the findings of scientists on the gradual appearance of life. In fact, the International Theological Commission in a July 2004 statement endorsed by Cardinal Ratzinger, then president of the Commission and head of the Congregation for the Doctrine of the Faith, later Pope Benedict XVI, now Pope Emeritus Benedict XVI, includes this paragraph:
According to the widely accepted scientific account, the universe erupted 15 billion years ago in an explosion called the 'Big Bang' and has been expanding and cooling ever since. Later there gradually emerged the conditions necessary for the formation of atoms, still later the condensation of galaxies and stars, and about 10 billion years later the formation of planets. In our own solar system and on earth (formed about 4.5 billion years ago), the conditions have been favorable to the emergence of life. While there is little consensus among scientists about how the origin of this first microscopic life is to be explained, there is general agreement among them that the first organism dwelt on this planet about 3.5–4 billion years ago. Since it has been demonstrated that all living organisms on earth are genetically related, it is virtually certain that all living organisms have descended from this first organism. Converging evidence from many studies in the physical and biological sciences furnishes mounting support for some theory of evolution to account for the development and diversification of life on earth, while controversy continues over the pace and mechanisms of evolution.
The Church's stance is that any such gradual appearance must have been guided in some way by God, but the Church has thus far declined to define in what way that may be. Commentators tend to interpret the Church's position in the way most favorable to their own arguments. The ITC statement includes these paragraphs on evolution, the providence of God, and "intelligent design":
In freely willing to create and conserve the universe, God wills to activate and to sustain in act all those secondary causes whose activity contributes to the unfolding of the natural order which he intends to produce. Through the activity of natural causes, God causes to arise those conditions required for the emergence and support of living organisms, and, furthermore, for their reproduction and differentiation. Although there is scientific debate about the degree of purposiveness or design operative and empirically observable in these developments, they have de facto favored the emergence and flourishing of life. Catholic theologians can see in such reasoning support for the affirmation entailed by faith in divine creation and divine providence. In the providential design of creation, the triune God intended not only to make a place for human beings in the universe but also, and ultimately, to make room for them in his own trinitarian life. Furthermore, operating as real, though secondary causes, human beings contribute to the reshaping and transformation of the universe.
A growing body of scientific critics of neo-Darwinism point to evidence of design (e.g., biological structures that exhibit specified complexity) that, in their view, cannot be explained in terms of a purely contingent process and that neo-Darwinians have ignored or misinterpreted. The nub of this currently lively disagreement involves scientific observation and generalization concerning whether the available data support inferences of design or chance, and cannot be settled by theology. But it is important to note that, according to the Catholic understanding of divine causality, true contingency in the created order is not incompatible with a purposeful divine providence. Divine causality and created causality radically differ in kind and not only in degree. Thus, even the outcome of a truly contingent natural process can nonetheless fall within God's providential plan for creation.
In addition, while he was the Vatican's chief astronomer, Fr. George Coyne, issued a statement on 18 November 2005 saying that "Intelligent design isn't science even though it pretends to be. If you want to teach it in schools, intelligent design should be taught when religion or cultural history is taught, not science." Cardinal Paul Poupard added that "the faithful have the obligation to listen to that which secular modern science has to offer, just as we ask that knowledge of the faith be taken in consideration as an expert voice in humanity." He also warned of the permanent lesson we have learned from the Galileo affair, and that "we also know the dangers of a religion that severs its links with reason and becomes prey to fundamentalism." Fiorenzo Facchini, professor of evolutionary biology at the University of Bologna, called intelligent design unscientific, and wrote in the January 16–17, 2006 edition L'Osservatore Romano: "But it is not correct from a methodological point of view to stray from the field of science while pretending to do science.... It only creates confusion between the scientific plane and those that are philosophical or religious." Kenneth R. Miller is another prominent Catholic scientist widely known for opposing Young Earth Creationism and Intelligent Design. He writes, concerning Emeritus pope Benedict XVI, that "The Holy Father's concerns are not with evolution per se, but with how evolution is to be understood in our modern world. Biological evolution fits neatly into a traditional Catholic understanding of how contingent natural processes can be seen as part of God's plan...a careful reading suggests that the new pope will give quarter neither to the enemies of spirituality nor the enemies of evolutionary science. And that's exactly as it should be."
In a commentary on Genesis authored as Cardinal Ratzinger titled In the Beginning... Benedict XVI spoke of "the inner unity of creation and evolution and of faith and reason" and that these two realms of knowledge are complementary, not contradictory:
We cannot say: creation or evolution, inasmuch as these two things respond to two different realities. The story of the dust of the earth and the breath of God, which we just heard, does not in fact explain how human persons come to be but rather what they are. It explains their inmost origin and casts light on the project that they are. And, vice versa, the theory of evolution seeks to understand and describe biological developments. But in so doing it cannot explain where the 'project' of human persons comes from, nor their inner origin, nor their particular nature. To that extent we are faced here with two complementary—rather than mutually exclusive—realities.
— Cardinal Ratzinger, In the Beginning: A Catholic Understanding of the Story of Creation and the Fall (Eerdmans, 1995), p. 50.
In a book released in 2008, his comments prior to becoming Pope were recorded as:
The clay became man at the moment in which a being for the first time was capable of forming, however dimly, the thought of "God". The first Thou that—however stammeringly—was said by human lips to God marks the moment in which the spirit arose in the world. Here the Rubicon of anthropogenesis was crossed. For it is not the use of weapons or fire, not new methods of cruelty or of useful activity, that constitute man, but rather his ability to be immediately in relation to God. This holds fast to the doctrine of the special creation of man ... herein ... lies the reason why the moment of anthropogenesis cannot possibly be determined by paleontology: anthropogenesis is the rise of the spirit, which cannot be excavated with a shovel. The theory of evolution does not invalidate the faith, nor does it corroborate it. But it does challenge the faith to understand itself more profoundly and thus to help man to understand himself and to become increasingly what he is: the being who is supposed to say Thou to God in eternity.
— Joseph Ratzinger
On September 2–3, 2006 at Castel Gandolfo, Pope Benedict XVI conducted a seminar examining the theory of evolution and its impact on Catholicism's teaching of Creation. The seminar is the latest edition of the annual "Schülerkreis" or student circle, a meeting Benedict has held with his former Ph.D. students since the 1970s. The essays presented by his former students, including natural scientists and theologians, were published in 2007 under the title Creation and Evolution (in German, Schöpfung und Evolution). In Pope Benedict's own contribution he states that "the question is not to either make a decision for a creationism that fundamentally excludes science, or for an evolutionary theory that covers over its own gaps and does not want to see the questions that reach beyond the methodological possibilities of natural science", and that "I find it important to underline that the theory of evolution implies questions that must be assigned to philosophy and which themselves lead beyond the realms of science."
In July 2007 at a meeting with clergy Pope Benedict XVI noted that the conflict between "creationism" and evolution (as a finding of science) is "absurd:" 
Currently, I see in Germany, but also in the United States, a somewhat fierce debate raging between so-called "creationism" and evolutionism, presented as though they were mutually exclusive alternatives: those who believe in the Creator would not be able to conceive of evolution, and those who instead support evolution would have to exclude God. This antithesis is absurd because, on the one hand, there are so many scientific proofs in favour of evolution which appears to be a reality we can see and which enriches our knowledge of life and being as such. But on the other, the doctrine of evolution does not answer every query, especially the great philosophical question: where does everything come from? And how did everything start which ultimately led to man? I believe this is of the utmost importance.
In commenting on statements by his predecessor, he writes "it is also true that the theory of evolution is not a complete, scientifically proven theory." Though commenting that experiments in a controlled environment were limited as "we cannot haul 10,000 generations into the laboratory", he does not endorse Young Earth Creationism or intelligent design. He defends theistic evolution, the reconciliation between science and religion already held by Catholics. In discussing evolution, he writes that "The process itself is rational despite the mistakes and confusion as it goes through a narrow corridor choosing a few positive mutations and using low probability.... This ... inevitably leads to a question that goes beyond science.... Where did this rationality come from?" to which he answers that it comes from the "creative reason" of God.
Catholic teaching and evolution
The Catechism of the Catholic Church (1994, revised 1997) on faith, evolution and science states:
159. Faith and science: "... methodical research in all branches of knowledge, provided it is carried out in a truly scientific manner and does not override moral laws, can never conflict with the faith, because the things of the world and the things of faith derive from the same God. The humble and persevering investigator of the secrets of nature is being led, as it were, by the hand of God in spite of himself, for it is God, the conserver of all things, who made them what they are." (Vatican II GS 36:1)
283. The question about the origins of the world and of man has been the object of many scientific studies which have splendidly enriched our knowledge of the age and dimensions of the cosmos, the development of life-forms and the appearance of man. These discoveries invite us to even greater admiration for the greatness of the Creator, prompting us to give him thanks for all his works and for the understanding and wisdom he gives to scholars and researchers....
284. The great interest accorded to these studies is strongly stimulated by a question of another order, which goes beyond the proper domain of the natural sciences. It is not only a question of knowing when and how the universe arose physically, or when man appeared, but rather of discovering the meaning of such an origin....
Paragraph 283 has been noted as making a positive comment regarding the theory of evolution, with the clarification that "many scientific studies" that have enriched knowledge of "the development of life-forms and the appearance of man" refers to mainstream science and not to "creation science".
Concerning the doctrine on creation, Ludwig Ott in his Fundamentals of Catholic Dogma identifies the following points as essential beliefs of the Catholic faith ("De Fide"):
- All that exists outside God was, in its whole substance, produced out of nothing by God.
- God was moved by His Goodness to create the world.
- The world was created for the Glorification of God.
- The Three Divine Persons are one single, common Principle of the Creation.
- God created the world free from exterior compulsion and inner necessity.
- God has created a good world.
- The world had a beginning in time.
- God alone created the world.
- God keeps all created things in existence.
- God, through His Providence, protects and guides all that He has created.
Unofficial Catholic organizations
There have been several organizations composed of Catholic laity and clergy which have advocated positions both supporting evolution and opposed to evolution, as well as individual figures such as Bruce Chapman. For example:
- The Kolbe Center for the Study of Creation operates out of Mt. Jackson, Virginia and is a Catholic lay apostolate promoting creationism.
- The "Faith Movement", was founded by Catholic priests Fr. Edward Holloway and Fr. Roger Nesbitt in Surrey, England and "argues from Evolution as a fact, that the whole process would be impossible without the existence of the Supreme Mind we call God."
- The "Daylight Origins Society" was founded in 1971 by John G. Campbell (d.1983) as the "Counter Evolution Group". Its goal is "to inform Catholics and others of the scientific evidence supporting Special Creation as opposed to Evolution, and that the true discoveries of Science are in conformity with Catholic doctrines." It publishes the "Daylight" newsletter.
- The Center for Science and Culture of the Discovery Institute was founded, in part, by Catholic biochemist Michael Behe, who is currently a senior fellow at the Center.
There are many Catholic organizations who gain insight into the relation between Catholic faith and evolution theory from the writings of Fr. Pierre Teilhard de Chardin S.J. Despite occasional objections to aspects of his thought, Teilhard was never condemned by the magisterial church.
The website "catholic.net", successor to the "Catholic Information Center on the Internet", sometimes features polemics against evolution. Many "traditionalist" organizations are also opposed to evolution, see e.g. the theological journal Living Tradition.

Many of Schonborn's complaints about Darwinian evolution echoed pronouncements originating from the Discovery Institute, the right-wing American think tank that plays a central role in the ID movement (and whose public relations firm submitted Schonborn's article to the Times)."

"Miffed by Krauss's comments, officers at the Discovery Institute arranged for the cardinal archbishop of Vienna, Cristoph Sconborn (b. 1945), to write an op-ed piece for the Times dismissing the late pope's statement as "rather vague and unimportant" and denying the truth of "evolution in the neo-Darwinian sense—an unguided, unplanned process of random variation and natural selection". The cardinal, it seems, had received the backing of the new pope, Benedict XVI, the former Joseph Ratzinger (b. 1927), who in the mid-1980s, while serving as prefect of the Sacred Congregation of the Doctrine of the Faith, successor to the notorious Inquisition, had written a defense of the doctrine of creation agasint Catholics who stressed the sufficiency of "selection and mutation". Humans, Benedict XVI insisted, are "not the products of chance and error", and "the universe is not the product of darkness and unreason. It comes from intelligence, freedom, and from the beauty that is identical with love." Recent discoveries in microbiology and biochemistry, he was happy to say, had revealed "reasonable design.""
