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. One of his converts, a former rabbi by the name of Solomon ha-Levi, went on to become the Bishop of Cartagena and later the Archbishop of Burgos. Vincent is alleged to have contributed to anti-Semitism in Spain, as violence accompanied his visits to towns that had Jewish communities.
