Apparently his late Majesty wrote a treatise (Assertio Septem Sacramentorum adversus Martinum Lutherum) against Martin Luther, which so pleased the Pope of the time that he bestowed the title "Defender of the Faith" on Henry and his successors (indeed it is still borne by our sovereign lady, the present Queen).

Luther wrote a reply, and it is presumably from that work that the quotation comes.

Yes, Henry was well-known in his younger years for being a keen tennis player. I have a vague memory of having seen the real tennis courts where he played at Hampton Court.
