"The late Raymond Brown always insisted that the itinerant preacher we follow never intended to found a church as we know it."  Brown was an academic & such items are easily buried in scholarly work. "Always insisted?"  To whom?  The USCCB?  Did Brown ever flesh out his ecclesiology?  The RCC is patterned more on the Roman Empire of Constantine that the itinerant preacher of Palestine. The first title popes proudly post is Pontifex Maximus.  Or, P.M. as it is chiseled on pope tombs, etc.  Clearly a hold-over from pagan Rome.  If as Brown & other biblical scholars claim Jesus was primarily an itinerant preacher why not I.P.?
