Testwood was a moderately well-known musician and gained a place as a chorister at Windsor College.
One, with a chantry priest, Mr. Ely, was about whether laymen should read the scriptures and whether the Pope should be the supreme head of the church in England.
After asserting that men should read the scriptures and that the King should lead the church in England, Testwood was called 'the greatest heretic that ever came into Windsor' by Ely.
