Technically our church's take on theology is a bit different from the later churches because, for one, Paul was still the enemy!
And that's a good thing ~ you can just imagine how many disputes are eliminated if you don't have to take Paul at his word, but simply as another advisor.
BTW, that first century thing was just an ambition. You really have to move on in your thinking into the second century ~ else you get those folks Paul warned against.
yes, he left the congregation in jersusalem, with peter in charge....as he ordained earlier....
the first century is rife with important history, why this gets ignored is fairly obvious....read over Faith of the Fathers, who in their writings from that very era, show the utter catholicity and the kernels of the beginnings of the church, magesterium, and sacred tradition, that the the guiding hallmark of His church today.
