According to your reasoning, therefore, there were no Christians until the believers were called Christians in Antioch.

Exactly what reasoning of mine are you referring to?

[adiaireton8]

The body of believers is never called "Catholic" (Roman or otherwise) in scripture. That organization came about officially hundreds of years later.

That reasoning. You seem to use the absence of the term 'catholic' from the NT as evidence that the early Church was not the Catholic Church. But, as I just pointed out, that same reasoning would entail that there were no Christians at least until the Gospel reached Antioch.
