It is well known that Newton was not only religious but what we today call fundamentalist — to such an extent that he jeopardized his academic career rather than swear loyalty to a variety of Christian theology that he feared would imperil his immortal soul.
But I think it is not clearly remembered today that he was an actual creationist. The second edition of Principia contains an Appendix on the attraction of bodies, which begins:
This most beautiful system of the sun, planets and comets, could only proceed from the counsel and dominion of an intelligent and powerful Being.
Why put this into a book of mathematics and physics? Because this was a physical consideration for Newton. He continues, concluding that
God suffers nothing from the motion of bodies; bodies find no resistance from the omnipresence of God.
(Quoted from Richard Westfall, The Life of Isaac Newton, [Cambridge: Cambridge University Press; Canto edition, 1994], p. 290.)
