"True Orthodoxy" Debunked

UPDATE: ROCOR didn't schism from the Orthodox world and are united with the MP today (2:40-2:50). When I was talking about the Sabbath I falsely stated that the Pharisees were on the mercy seat. The Pharisees were sitting on the seat of Moses.

Sources for most of my arguments are the following:
