Michael, also called Saint Michael the Archangel, Archangel Michael and Saint Michael the Taxiarch is an archangel in Judaism, Christianity, Islam, and the Baha'i faith. The earliest surviving mentions of his name are in 3rd and 2nd-century BC Jewish works, often but not always apocalyptic, where he is the chief of the angels and archangels, and he is the guardian prince of Israel and is responsible for the care of Israel. Christianity adopted nearly all the Jewish traditions concerning him, and he is mentioned explicitly in Revelation 12:7–12, where he does battle with Satan, and in the Epistle of Jude, where the author denounces heretics by contrasting them with Michael.
