Speaking of silly assertions, here's one.
"Received as inspired"? By whom? Who has the authority to "receive" something as "inspired"? The Church, of course. But which church? Where? How?
"Before Roman Catholicism developed"? When did that happen, exactly, and more importantly, where's the proof? Not just handwaving ahistorical inventions like "Constantine did it" or "Leo did it," where's the proof that the faith of the Roman Christians was organically changed between AD 200 and AD 450? There isn't any.
And there was plenty of dissension over the content of the NT throughout the first four centuries, which is why two Catholic councils and a Papal decree between AD 380 and AD 410 were required to settle the matter. That's why the Shepherd of Hermas and the Epistles of Clement aren't in your 66 book Bible.
I can think of only one book that was “received as inspired” and uses that claim as its sole basis of authority.
