early CHURCH history part 4

st another artificial intelligence assisted research video, we explore the term old Catholicism and its opposition to roman Catholicism.
roman catholic church is based on the old Greek byzantine empire religion and it only recently became the dominant form. the protestant reformation was a key moment in the fight to keep the roman catholics from expanding. its an important part of church history that brings up the question.

well we can't be certain of much but the old cathedrals are evidence to a time where the world worked much differently.
