For Newton the world of science was by no means the whole of life. He spent more time on theology than on science; indeed, he wrote about 1.3 million words on biblical subjects. Yet this vast legacy lay hidden from public view for two centuries until the auction of his nonscientific writings in 1936.
Newton’s understanding of God came primarily from the Bible, which he studied for days and weeks at a time. He took special interest in miracles and prophecy, calculating dates of Old Testament books and analyzing their texts to discover their authorship. In a manuscript on rules for interpreting prophecy, Newton noted the similar goals of the scientist and the prophecy expositor: simplicity and unity. He condemned the “folly of interpreters who foretell times and things by prophecy,” since the purpose of prophecy was to demonstrate God’s providence in history when “after [prophecies] were fulfilled, they might be interpreted by events.”
A member of the Anglican church, Newton attended services and participated in special projects, such as paying for the distribution of Bibles among the poor, and serving on a commission to build fifty new churches in the London area. Yet Newton seldom made public pronouncements regarding his theology. He is remembered instead for his pioneering scientific achievements.
In his famous Principia, Newton wrote: “This Being governs all things, not as the soul of the world, but as Lord over all. . . . The Supreme God is a Being eternal, infinite, absolutely perfect . . . and from his true dominion it follows that the true God is a living, intelligent, and powerful Being. . . . He is not eternity and infinity, but eternal and infinite; he is not duration or space, but he endures and is present.”[7]
