Johnbull - despite Vaquero100's one man campaign to reclaim the name Catholic Church for his employer, it is not polite to revert his edits without discussing first.  In this case I think he is justified to use Catholic Church, and 'Henry was a devout Catholic' as when referring to 1510 that was unambiguous.  However, I think the "external authority of the Catholic Church" is a very clumsy phrase when all that is meant was the Primacy of the Roman Pontiff.   Many other things changed in the English Reformation, but the only thing that changed as regards external authority over the English Church was that the Pope was replaced with the Supreme Governor (English monarch.)
