(FREDERICUS) (Saint) Martyr (July 18) (9th century) The grandson of Radbod, King of the Frisians and from his youth trained up in piety. In the year 820, chosen Bishop of Utrecht, he worked zealously to extirpate idolatry from Friesland. He reproved with Apostolic freedom Judith, the second wife of Louis the Debonnaire, and also the incestuous inhabitants of Walcheren, thereby d;rawing upon himself their enmity. After saying Mass he was stabbed to death in the Chanel of Saint John the Baptist (July 18, A.D. 838), some say by the order of Judith, others by assassins hired “by the inhabitants of Walcheren.
