The general conclusion of most theologians for centuries is that the theological work of Newton was almost pure gibberish. A lot of his writing was nonsense and does not work well with traditional Christian doctrine. Or "safely ignored" as he put it. Newton fancied himself a theologian, who dabbled in science and math as an adjunct to his theological studies. As it happens, his science and math work had great value even though the theological context in which they were discovered is widely considered to be garbage within theological circles. I find it fascinating that such a fundamentally influential figure in the math and sciences developed these theories almost as a historical accident that resulted from his "lunatic fringe" obsession with Christian theology. Apparently his mind served him much more poorly in his theological pursuits than in his accidental incursions into math and science, but then there are many that believe Newton wasn't entirely "right in the head". A mad genius perhaps?
