Ruze, Guillaume, a French prelate, was born at Paris about 1530. He taught rhetoric and philosophy in the College of Navarre, where he received the degree of doctor. He was councilor under Henry II, Charles IX, and Henry III, who made him grand almoner. In 1570 he was promoted to the bishopric of Saint-Malo, but resigned it two years later to receive that of Angers. In 1583 he assisted at the Council of Tours, and rendered into French the confession of faith adopted by that council. He was also the author of a French translation of the Commonitorium adversus Hoereticos of Vincent de Lerius. Ruze died Sept. 28, 1587. See Gallia Christiana.
