“He had been advised from folks who lived there.”
That would imply organization, would it not, such that Paul would be informed of goings on in distant cities. See, you can’t square the circle. The communities were in communication with each other and they had an established heirarchy in the Apostles, who were their caretakers.
My goodness, that is a stretch. From writing to a close friend, who happens to be a well-read scholar of the OT, an apostle of the first magnitude, a fellow general contractor, to help advise them what to do with the quarrels/strife that cropped up between self-righteous Jewish believers and non-Jewish believers you can deduce, "...an established hierarchy in the Apostles, who were their caretakers."? Okay, we need to get you off the caffeine. No wonder we ended up with a cult in Rome.
