Well I just suggest you don’t take it from me, but read God’s Word. It’s better than hidden treasure you know.
Nothing in the Bible speaks of a vast population of Christians of antiquity that were neither Roman or Byzantine Catholic.
Through the majority of the Christian era, the vast majority of Christians have been either Roman or Byzantine Catholic.
That is simply historic fact. Despite how it rubs your anti-Catholic sensibilities the wrong way.
I am concerned with you supporting your contention that there was somehow this vast population of non-Roman or Byzantine Catholic Christians.
Where did they live?
Who were they?
Where did they go?
Throwing up another source that does nothing to support your contention just makes you look like more of a fool.
