Angelus of Jerusalem was a 13th-century Carmelite priest born in Jerusalem to Jewish parents. Following his mother's conversion to Christianity, he and his twin brother entered the religious life. After his ordination in 1210, he lived as a hermit in the desert to avoid the fame brought by his reputation as a healer. He later traveled to Italy to preach and to seek papal approval for a new rule for his order. While preaching in Licata, Sicily, he was killed by an enraged man he had attempted to convert.
