Not a problem. We wrangled all that out with Monsignor when we joined up. The only matters we differed on were the validity of Anglican Orders and the supremacy of the Bishop of Rome, and we were happy to relinquish those points (especially since the Orders have sort of proved their invalidity - by their fruits shall ye know them, and it's obvious that Adult Leadership is necessary).
That's simple.
That Benedict IS Peter is not simple.
How did you get past that?
