Newton is more often cited as a Deist. He is another example of one who, as he undertook science, assumed the universe was created by God with established rules to govern it, and so intelligent design was the background against which he pursued his vocation as a student, scientist, and philosopher.
I agree with that, but I believe Newton denied being a Deist. He had his own personal brand of heresy, one that he distanced from his public life.
But Newton’s foibles are of little interest to me. Scientists of his time followed the evidence and expected the evidence to confirm the history of the universe according to Moses.
The split between religion and science began when the evidence diverged from this expectation, and science continued following the evidence.
