 Henry married his last wife , the wealthy widow Catherine Parr , in July 1543 . A reformer at heart , she argued with Henry over religion . Ultimately , Henry remained committed to an idiosyncratic mixture of Catholicism and Protestantism ; the reactionary mood which had gained ground following the fall of Cromwell had neither eliminated his Protestant streak nor been overcome by it . Parr helped reconcile Henry with his daughters Mary and Elizabeth . In 1543 , an Act of Parliament put the daughters back in the line of succession after Edward , Prince of Wales . The same act allowed Henry to determine further succession to the throne in his will .
