I am convinced that few Protestants think much of the words of Christ, considering Paul a "canon within the canon". This has been explicitly mentioned by some Protestant apologists, claiming Jesus never really spoke much about the "real" Gospel of "Faith Alone" - so they must turn to Paul and twist it from Romans and Galatians...
Even there, I can show that Paul and James and Jesus are on the same page...

The Church never considered it anything but that, jo, East or West.
