I know everyone has answered this already - but there wasn't really a formal thing called 'Protestantism' then, that's the name attached to it later. Henry was still a Catholic, just one who wanted to make himself the head of the Catholic Church in his own country instead of the Pope.
This is what I find really thrilling - the danger and excitement of hearing the Word of God in your own language, that it was something people were prepared to die for. The power of putting that knowledge in your own tongue, not hiding behind the glamour and mystery of the Mass. So much came from that one thing, the bible in native languages. (I'm an atheist, by the way, but I'm definitely a CofE atheist!)
