Michael (also called Saint Michael the Archangel, Saint Michael, Saint Michael the Taxiarch in Orthodoxy and Archangel Michael) is an archangel in Judaism, Christianity, and Islam.
The earliest surviving mentions of his name are in 3rd and 2nd century BCE Jewish works, often but not always apocalyptic, where he is the chief of the angels and archangels and 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 the Michael. In surah 2:98 of the Quran the Jews of Medina challenge Muhammed to tell them the name of the angel from whom he received revelation, and when he told that it was Gabriel they reply that revelations came from Michael.
