Antipope Clement VII lived at Avignon in France, and Pope Urban VI in Rome. Vincent was convinced that the election of Urban was invalid, although Catherine of Siena was just as devoted a supporter of the Roman pope. In the service of Cardinal Pedro de Luna, Vincent worked to persuade Spaniards to follow Clement. When Clement died in 1394, Cardinal de Luna was elected as the second antipope successor to the Avignon papacy and took the name Benedict XIII. Vincent and his brother Boniface, General of the Carthusians, were loyal to Benedict XIII, commonly known as "Papa Luna" in Castile and Aragon. He worked for Benedict XIII as apostolic penitentiary and Master of the Sacred Palace. Nonetheless Vincent labored to have Benedict XIII end the schism. When Benedict XIII did not resign as intended at either the Council of Pisa (1409) or the Council of Constance (1414–1418), he lost the support of the French king and of most of his cardinals, and was excommunicated as a schismatic in 1417. Vincent later claimed that the Western Schism had had such a depressing effect on his mind that it caused him to be seriously ill. Religious gifts and missionary work For twenty-one years he was said to have traveled to England, Scotland, Ireland, Aragon, Castile, France, Switzerland, and Italy, preaching the Gospel and converting many. Many biographers believe that he could speak only Catalan, but was endowed with the gift of tongues. He was a noted preacher. Though he himself was an intellectual, his preaching style has been described as "innovative in that it incorporated a popular tone and rhetorical directness into the (by then traditional) Scholastic, thematic sermon structure". He preached to Colette of Corbie and her nuns, and it was she who told him that he would die in France. Too ill to return to Spain, he did, indeed, die in Brittany in 1419. Breton fishermen still invoke his aid in storms, and in Spain he is the patron of orphanages. Conversion of Jews and controversy Vincent is said to have been responsible for the conversion of many Jews to Catholicism, often by questionable means according to the Jewish Encyclopedia; for instance, he is said to have made their lives difficult until they converted and to have "dedicated" synagogues as churches on the basis of his own authority.
