Rabbi Tovia Singer of Outreach Judaism in responding to a question about Jesus claiming to be God said:
However, when the Greek and Roman rather than the Hebrew began to dominate the church, it created a theological disaster from which Christendom has never recovered. By the end of the fourth century, the doctrine of the Trinity was firmly in place as a central tenet of the church, and strict monotheism was formally rejected by Vatican councils in Nicea and Constantinople.
The entire response is equally as unconvincing but this jumped out at me immediately. I find it interesting that two councils held in present day Turkey are called ‘Vatican Councils’ — especially given the sparse representation of the Western part of the empire in said meetings. Accuracy flies out the window when engaging in polemics ;)
