Let's put this in context. Conservatives were very willing to cast stones at Bill Clinton for his affair. Imagine if he wanted to get rid of Hillary and marry his mistress, Monica. Hillary refuses. Then Bill Clinton has everyone in America sign a document that his marriage to Hillary was not valid and his marriage with Monica would be the valid marriage. Whoever protests is killed by Bill Clinton. Bill Clinton is supported by clergymen like Jesse Jackson and Al Sharpton.
When Chelsea Clinton grows up, she has Jesse Jackson and Al Sharpton killed.
I am sorry for being uncharitable, but I would not consider Jesse Jackson and Al Sharpton to be martyrs of the faith if Chelsea Clinton was responsible for their death. They may have given great speeches or wrote great prayers, but still...
Many Protestants of that day believed the institution of the papacy -- not the Pope, as you incorrectly note -- was the Antichrist.
Thomas Cranmer said: "Whereof it followeth Rome to be the seat of antichrist, and the pope to be very antichrist himself. I could prove the same by many other scriptures, old writers, and strong reasons." (Referring to prophecies in Revelation and Daniel.)
Cranmer's greater contribution was the Book of Common Prayer, which has enlightened our minds and spirits ever since.
Here I agree with you. Some of the great composers were not men of great faith and fidelity to the truth, but their music does uplift our spirits.
