Please show me where in scripture where Jesus formed multiple churches and said all theologies were valid.
Would you settle for showing a half dozen or so places where the Lord condemns Roman Catholic practices?
Seems to me that the Revelation, written to the seven churches in Asia, would represent a plurality of churches ... and being a plurality, would consititute the multiple that you are asking evidence for.
Is 7 enough? There were certainly others. This clearly establishes from scripture a plurality of churches. Also, since Christ has different words of encouragement and rebuke for each of them, wouldn't it stand to reason that they differed in doctrine?
Perhaps you could explain why Christ addresses the churches themselves individually, and not the pope at the time. I find it impossible to believe, that Jesus Christ did not address the pope at the time, begin His representative on Earth over the church ... instead he addressed the individual churches.
Why no message to the church at Rome? Seems like if Rome held a primary role in the early church that Jesus would have had something to say to the church at Rome.
Its a slam dunk in my book.
