Raphael ("God, Please Heal") is an archangel of Judaism and Christianity, who in the Judeo-Christian tradition performs all manners of healing. In Islam, Raphael is the fourth major angel; in Muslim tradition, he is known as Israfil. Raphael is mentioned in the Book of Tobit, which is accepted as canonical by Catholics, Orthodox, and some Anglo-Catholics, and as useful for public teaching by Lutherans and Anglicans. Raphael is generally associated with the angel mentioned in the Gospel of John as stirring the water at the healing pool of Bethesda.
