The English Church preceded Augustine. My guess is that was why Henry VIII felt comfortable telling the pope to go blow smoke.
Hey, wait: I'm the ex-Episcopalian here. You think I don't know that?
But it's not just the pre-Augustinian period. All the way up to Henry VIII and throughout Europe the role and authority of the Bishop of Rome was controversial. Don't forget, the official promulgation, declaration, definition, etc. of Papal Infallibility is less than a couple of centuries old. Whichever side one thinks was right, it would be hard to maintain that there wasn't controversy.
