Religious views of Isaac Newton
Isaac Newton (4 January 1643 – 31 March 1727) was considered an insightful and erudite theologian by his contemporaries. He wrote many works that would now be classified as occult studies and religious tracts dealing with the literal interpretation of the Bible.
Newton's conception of the physical world provided a stable model of the natural world that would reinforce stability and harmony in the civic world. Newton saw a monotheistic God as the masterful creator whose existence could not be denied in the face of the grandeur of all creation. Although born into an Anglican family, by his thirties Newton held a Christian faith that, had it been made public, would not have been considered orthodox by mainstream Christianity; in recent times he has been described as a heretic.
Newton was born into an Anglican family three months after the death of his father, a prosperous farmer also named Isaac Newton. When Newton was three, his mother married the rector of the neighbouring parish of North Witham and went to live with her new husband, the Reverend Barnabus Smith, leaving her son in the care of his maternal grandmother, Margery Ayscough. Isaac apparently hated Smith, and had no relations with him during his childhood. His maternal uncle, the rector serving the parish of Burton Coggles, was involved in some part in the care of Isaac.
In 1667 Newton became a Fellow of Trinity College, Cambridge, making necessary his commitment to taking Holy Orders within seven years of completing his MA, which he did the following year. He was also required to take a vow of celibacy and recognize the Thirty-Nine Articles of the Church of England. Newton considered ceasing his studies prior to completion in order to avoid the ordination made necessary by law of King Charles II. He was eventually successful in avoiding the statute, assisted in this by the efforts of Isaac Barrow, as in 1676 the then State Secretary Joseph Williamson changed the relevant statute of Trinity College to provide dispensation from this duty. Having foregone these duties, he embarked on an investigative study of the early history of the Church, during the 1680s succeeding into inquiries of the origins of religion instead, at about the same time as having developed a scientific view on motion and matter. Of Philosophiæ Naturalis Principia Mathematica he stated:
When I wrote my treatise about our Systeme I had an eye upon such Principles as might work with considering men for the beliefe of a Deity and nothing can rejoyce me more then to find it useful for that purpose.
Newton's religious views developed as a result of participation in an investigative discourse with Nature (the nature of the world) and developed from the apparent dichotomy of biblical reality from the increasing revealing of the structure of reality from investigation, and the subsequent challenges these truths of nature posed toward established religion for Newton, especially in light of Christian scriptural belief. Unorthodoxy was made necessary for Newton, and those affiliated with him, by the need for rediscovery of a prisca truth that had been hidden somewhere in the time of classical history. By this they might have the capacity to engage in open dialogue with an investigation into Nature. In this conflict of ecclesiastical order and the liberating effects of scientific enquiry, he and others turned to the prisca in all the security of a classical civilization having been supposedly founded on bona fide insights. So, for them, the truth lay within the perception of reality attained by Pythagoras and communicated, supposedly in a secret way, to a specific circle of people.
As is found among some of the established intellectuals of the Renaissance age, Newton believed that ancient philosophers and religious persons had gained insight into the truth of the nature of the world and universe, but this truth having become hidden within the language of the recording of the truth at the time and by later medieval scholars (Albertus Magnus, Arnold of Villanova and Roger Bacon) that required deciphering in order to be understood. The belief in the wisdom of the ancients, that thinking was intelligent and knowing in the civilization of classical religious figures (Jesus of Nazareth, the prophet Isaiah and Solomon) and writers (Plato and Democritus) is known as prisca sapientia.
Like many contemporaries (e.g., Thomas Aikenhead) he lived with the threat of severe punishment if he had been open about his religious beliefs. Heresy was a crime that could have been punishable by the loss of all property and status or even death (see, e.g., the Blasphemy Act 1697). Because of his secrecy over his religious beliefs, Newton has been described as a Nicodemite.
According to most scholars, Newton was Arian, not holding to Trinitarianism. 'In Newton's eyes, worshipping Christ as God was idolatry, to him the fundamental sin'. As well as being antitrinitarian, Newton allegedly rejected the orthodox doctrines of the immortal soul, a personal devil and literal demons. Although he was not a Socinian he shared many similar beliefs with them. A manuscript he sent to John Locke in which he disputed the existence of the Trinity was never published. In a minority view, T.C. Pfizenmaier argued Newton was neither "orthodox" nor an Arian, but that, rather, Newton believed both of these groups had wandered into metaphysical speculation. Pfizenmaier also argued that Newton held closer to the Eastern Orthodox view of the Trinity rather than the Western one held by Roman Catholics and Protestants. However, S. D. Snobelen has argued against this from manuscripts produced late in Newton's life which demonstrate Newton rejected the Eastern view of the Trinity.
God as masterful creator
Newton saw God as the masterful creator whose existence could not be denied in the face of the grandeur of all creation. Nevertheless, he rejected Leibniz' thesis that God would necessarily make a perfect world which requires no intervention from the creator. In Query 31 of the Opticks, Newton simultaneously made an argument from design and for the necessity of intervention:
For while comets move in very eccentric orbs in all manner of positions, blind fate could never make all the planets move one and the same way in orbs concentric, some inconsiderable irregularities excepted which may have arisen from the mutual actions of comets and planets on one another, and which will be apt to increase, till this system wants a reformation.
This passage prompted an attack by Leibniz in a letter to his friend Caroline of Ansbach:
Sir Isaac Newton and his followers have also a very odd opinion concerning the work of God. According to their doctrine, God Almighty wants to wind up his watch from time to time: otherwise it would cease to move. He had not, it seems, sufficient foresight to make it a perpetual motion.
Leibniz' letter initiated the Leibniz-Clarke correspondence, ostensibly with Newton's friend and disciple Samuel Clarke, although as Caroline wrote, Clarke's letters "are not written without the advice of the Chev. Newton". Clarke complained that Leibniz' concept of God as a "supra-mundane intelligence" who set up a "pre-established harmony" was only a step from atheism: "And as those men, who pretend that in an earthly government things may go on perfectly well without the king himself ordering or disposing of any thing, may reasonably be suspected that they would like very well to set the king aside: so, whosoever contends, that the beings of the world can go on without the continual direction of God...his doctrine does in effect tend to exclude God out of the world".
In addition to stepping in to re-form the solar system, Newton invoked God's active intervention to prevent the stars falling in on each other, and perhaps in preventing the amount of motion in the universe from decaying due to viscosity and friction. In private correspondence Newton sometimes hinted that the force of Gravity was due to an immaterial influence:
Tis inconceivable that inanimate brute matter should (without the mediation of something else which is not material) operate upon & affect other matter without mutual contact.
Leibniz jibed that such an immaterial influence would be a continual miracle; this was another strand of his debate with Clarke.
Newton's view has been considered to be close to deism and several biographers and scholars labeled him as a deist who is strongly influenced by Christianity. However, he differed from strict adherents of deism in that he invoked God as a special physical cause to keep the planets in orbits. He warned against using the law of gravity to view the universe as a mere machine, like a great clock. He said:
This most beautiful system of the sun, planets, and comets, could only proceed from the counsel and dominion of an intelligent Being. [...] This Being governs all things, not as the soul of the world, but as Lord over all; and on account of his dominion he is wont to be called "Lord God" παντοκρατωρ [pantokratōr], or "Universal Ruler". [...] The Supreme God is a Being eternal, infinite, [and] absolutely perfect.
On the other hand, latitudinarian and Newtonian ideas taken too far resulted in the millenarians, a religious faction dedicated to the concept of a mechanical universe, but finding in it the same enthusiasm and mysticism that the Enlightenment had fought so hard to extinguish. Newton himself may have had some interest in millenarianism as he wrote about both the Book of Daniel and the Book of Revelation in his Observations Upon the Prophecies.
Newton's conception of the physical world provided a stable model of the natural world that would reinforce stability and harmony in the civic world.
Newton spent a great deal of time trying to discover hidden messages within the Bible. After 1690, Newton wrote a number of religious tracts dealing with the literal interpretation of the Bible. In a manuscript Newton wrote in 1704 he describes his attempts to extract scientific information from the Bible. He estimated that the world would end no earlier than 2060. In predicting this he said "This I mention not to assert when the time of the end shall be, but to put a stop to the rash conjectures of fanciful men who are frequently predicting the time of the end, and by doing so bring the sacred prophesies into discredit as often as their predictions fail."
Newton relied upon the existing Scripture for prophecy, believing his interpretations would set the record straight in the face of what he considered to be, "so little understood". Though he would never write a cohesive body of work on Prophecy, Newton's beliefs would lead him to write several treatises on the subject, including an unpublished guide for prophetic interpretation entitled Rules for interpreting the words & language in Scripture. In this manuscript he details the necessary requirements for what he considered to be the proper interpretation of the Bible.
End of The World vs Start of The Millennial Kingdom
In his posthumously-published Observations upon the Prophecies of Daniel, and the Apocalypse of St. John, Newton expressed his belief that Bible prophecy would not be understood "until the time of the end", and that even then "none of the wicked shall understand". Referring to that as a future time ("the last age, the age of opening these things, be now approaching"), Newton also anticipated "the general preaching of the Gospel be approaching" and "the Gospel must first be preached in all nations before the great tribulation, and end of the world".
Over the years, a large amount of media attention and public interest has circulated regarding largely unknown and unpublished documents, evidently written by Isaac Newton, that indicate he believed the world could end in 2060. While Newton also had many other possible dates (e.g. 2034), he did not believe that the end of the world would take place specifically in 2060.
Like most Protestant theologians of his time, Newton believed that the Papal Office, (and not any one particular Pope) was the fulfillment of the Biblical predictions about Antichrist, whose rule was predicted to last for 1,260 years. They applied the day-year principle (in which a day represents a year in prophecy) to certain key verses in the books of Daniel and Revelation (also known as the Apocalypse), and looked for significant dates in the Papacy's rise to power to begin this timeline. Newton's calculation ending in 2060 is based on the 1,260-year timeline commencing in 800 AD when Charlemagne became the first Holy Roman Emperor and reconfirmed the earlier (756 AD) Donation of Pepin to the Papacy.
2016 vs 2060
However, between the time he wrote his 2060 prediction (about 1704) until his death in 1727 Newton conversed, both first hand and by correspondence, with other famous theologians of his time. Those contemporaries who knew him during the remaining 23 years of his life appear to be in agreement that Newton, and the "best interpreters" including Jonathan Edwards, Robert Fleming, Moses Lowman, Phillip Doddridge, and Bishop Thomas Newton, were eventually "pretty well agreed" that the 1,260-year timeline should be calculated from the year 756 AD.
F.A. Cox also confirmed that this was the view of Newton and others, including himself:
“The author adopts the hypothesis of Fleming, Sir Isaac Newton, and Lowman, that the 1260 years commenced in A.d. 756; and consequently that the millennium will not begin till the year 2016.”
Thomas Williams stated that this timeline had become the predominant view among the leading Protestant theologians of his time:
“Mr. Lowman, though an earlier commentator, is (we believe) far more generally followed ; and he commences the 1260 days from about 756, when, by aid of Pepin, King of France, the Pope obtained considerable temporalities. This carries on the reign of Popery to 2016, or sixteen years into the commencement of the Millennium, as it is generally reckoned.”
In April of 756 AD, Pepin, King of France, accompanied by Pope Stephen II entered northern Italy, forcing the Lombard King Aistulf to lift his siege of Rome, and return to Pavia. Following Aistulf's capitulation, Pepin gave the newly conquered territories to the Papacy by means of the Donation of Pepin, thereby elevating the Pope from being a subject of the Byzantine Empire to head of state, with temporal power over the newly constituted Papal States.
The end of the timeline is based on Daniel 8:25 which reads "...but he shall be broken without hand" and is understood to mean that the end of the Papacy with not be caused by any human action. Volcanic activity is described as the means by which Rome will be overthrown.
"Antichrist will retain some part of his dominion over the nations till about the year 2016." "And when the 1260 years are expired, Rome itself, with all its magnificence, will be absorbed in a lake of fire, sink into the sea, and rise no more at all for ever*."
In 1870 the newly formed Kingdom of Italy annexed the remaining Papal States, depriving the Popes of any temporal rule for the next 59 years. Unaware that Papal rule would be restored, (albeit on a greatly diminished scale) in 1929 as head of the Vatican City state, the historicist view that the Papacy is the Antichrist, and the associated timelines delineating his rule rapidly declined in popularity as one of the defining characteristics of the Antichrist (i.e. that he would also be a political temporal power at the time of the return of Jesus) were no longer met.
Eventually, the prediction was largely forgotten and no major Protestant denomination currently subscribes to this timeline.
Despite the dramatic nature of a prediction of the end of the world, Newton may not have been referring to the 2060 date as a destructive act resulting in the annihilation of the earth and its inhabitants, but rather one in which he believed the world was to be replaced with a new one based upon a transition to an era of divinely inspired peace. In Christian theology, this concept is often referred to as The Second Coming of Jesus Christ and the establishment of Paradise by The Kingdom of God on Earth.
Henry More's belief in the universe and rejection of Cartesian dualism may have influenced Newton's religious ideas. Later works—The Chronology of Ancient Kingdoms Amended (1728) and Observations Upon the Prophecies of Daniel and the Apocalypse of St. John (1733)—were published after his death.
Newton and Boyle's mechanical philosophy was promoted by rationalist pamphleteers as a viable alternative to the pantheists and enthusiasts, and was accepted hesitantly by orthodox clergy as well as dissident preachers like the latitudinarians. The clarity and simplicity of science was seen as a way in which to combat the emotional and mystical superlatives of superstitious enthusiasm, as well as the threat of atheism.
The attacks made against pre-Enlightenment magical thinking, and the mystical elements of Christianity, were given their foundation with Boyle's mechanical conception of the universe. Newton gave Boyle's ideas their completion through mathematical proofs, and more importantly was very successful in popularizing them. Newton refashioned the world governed by an interventionist God into a world crafted by a God that designs along rational and universal principles. These principles were available for all people to discover, allowed man to pursue his own aims fruitfully in this life, not the next, and to perfect himself with his own rational powers.
His first writing on the subject of religion was Introductio. Continens Apocalypseos rationem generalem (Introduction. Containing an explanation of the Apocalypse), which has an unnumbered leaf between folios 1 and 2 with the subheading De prophetia prima, written in Latin some time prior to 1670. Written subsequently in English was Notes on early Church history and the moral superiority of the 'barbarians' to the Romans. His last writing, in 1737, was entitled A Dissertation upon the Sacred Cubit of the Jews and the Cubits of the several Nations. Newton did not publish any of his works of biblical study during his lifetime. All of Newton's writings on corruption in biblical scripture and the church took place after the late 1670s and prior to the middle of 1690.

Newton has often been identified as a deist. ...In the 19th century, William Blake seems to have put Newton into the deistic camp. Scholars in the 20th-century have often continued to view Newton as a deist. Gerald R. Cragg views Newton as a kind of proto-deist and, as evidence, points to Newton's belief in a true, original, monotheistic religion first discovered in ancient times by natural reason. This position, in Cragg's view, leads to the elimination of the Christian revelation as neither necessary nor sufficient for human knowledge of God. This agenda is indeed the key point, as Leland describes above, of the deistic program which seeks to "set aside" revelatory religious texts. Cragg writes that, "In effect, Newton ignored the claims of revelation and pointed in a direction which many eighteenth-century thinkers would willingly follow." John Redwood has also recently linked anti-Trinitarian theology with both "Newtonianism" and "deism."

Newton seems to have been closer to the deists in his conception of God and had no time for the doctrine of the Trinity. The deists did not recognize the divine nature of Christ. According to Fierz, Newton's conception of God permeated his entire scientific work: God's universality and eternity express themselves in the dominion of the laws of nature. Time and space are regarded as the 'organs' of God. All is contained and moves in God but without having any effect on God himself. Thus space and time become metaphysical entities, superordinate existences that are not associated with any interaction, activity or observation on man's part.
