To answer seriously, who is the Defender of the Faith? The monarchs of England, for example, were bestowed that title commencing with Henry VIII, by the then Pope, and continue to use it.
Henry Tudor was given it before his repudiation of the Faith and his physical takeover of the Church in England and all of its properties. Before the monasteries were emptied and the monks killed. Before the persecution of Catholics by the king and Cranmer. Before he killed St. Thomas More.
