Passage: 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.By 1672 he had started to record his theological researches in notebooks which he showed to no one and which have only recently been examined. They demonstrate an extensive knowledge of early church writings and show that in the conflict between Athanasius and Arius which defined the Creed, he took the side of Arius, the loser, who rejected the conventional view of the Trinity. Newton "recognized Christ as a divine mediator between God and man, who was subordinate to the Father who created him." He was especially interested in prophecy, but for him, "the great apostasy was trinitarianism."Newton tried unsuccessfully to obtain one of the two fellowships that exempted the holder from the ordination requirement. At the last moment in 1675 he received a dispensation from the government that excused him and all future holders of the Lucasian chair.In Newton's eyes, worshipping Christ as God was idolatry, to him the fundamental sin.  Historian Stephen D. Snobelen says, "Isaac Newton was a heretic. But ... he never made a public declaration of his private faith—which the orthodox would have deemed extremely radical. He hid his faith so well that scholars are still unravelling his personal beliefs." Snobelen concludes that Newton was at least a Socinian sympathiser (he owned and had thoroughly read at least eight Socinian books), possibly an Arian and almost certainly an anti-trinitarian.In a minority position, T.C. Pfizenmaier offers a more nuanced view, arguing that Newton held closer to the Semi-Arian view of the Trinity that Jesus Christ was of a "similar substance" (homoiousios) from the Father rather than the orthodox view that Jesus Christ is of the "same substance" of the Father (homoousios) as endorsed by modern Eastern Orthodox, Roman Catholics and Protestants. However, this...
