Defender Of The Faith

Latin  Fidei Defensor,   a title belonging to the sovereign of England in the same way as Christianissimus (“most Christian”) belonged to the king of France. The title was first conferred by Pope Leo X on Henry VIII (Oct. 11, 1521) as a reward for the king's pamphlet Assertio septem sacramentorum adversus Martinum Lutherum (“Declaration of the Seven Sacraments Against Martin Luther”), written against Luther.
