Carranza Bartolome joined the Dominican order in 1520, became a professor of theology at Valladolid, and attended the Council of Trent as a theologian in 1546. The confidant of Charles V and later Philip II, he accompanied Philip to England, and became confessor to Queen Mary. In 1558 he was appointed archbishop of Toledo and in the same year published his Comentarios sobre el catequismo cristiano, which brought the charge of heresy upon him by the Inquisition. Political motives prolonged the Inquisitorial process in Spain, during which he was kept in prison. By order of Pius V the process was transferred to Rome. On Apr. 14, 1576, Carranza was cleared of actual heresy but was asked to sign a condemnation of fourteen errors of which he had been suspected.
