Well, the Jewish influence primarily religious not cultural. The God of Abraham established a personal relationship with Abraham, and loyalty to “him” developed over the centuries into a rejection of all other gods. The constant fight to keep the Israelites from also worshipping other gods required a specific rejection of male-female fertilty duos. God does not “beget,” Which is where the Muslims also come from, that God does have a son. Which is why they reject the Incarnation. Which is why rationalists also reject the incarnation. The difference between Jews (and Muslims) is of course that for religious Jews, The Lord is a person, who is able to covenant with human being,m and for modernists he is reduced to a mere first principle, like the God of the philosophers who Pascal rejected. To them, of course, the Incarnation is a reversion to paganism, as it seems to Jews and Muslims. Arius followed the same impulse in advancing his Christology, But unitarianism does not save the evidence as well as Trintarianism. Nowhere can one deduce from the testimony of the Jews who were the first Christians any “simple” explanation for the events they depict. Arius was like Einstein when confronted with quantum physics:" God does not play dice,” he protested. Trintarianism is the quantum physics of theology. On the other hand, it is very different from the Hindu notion of trinity.
