The Investiture of the Archangel Michael (alternatively, the Book of the Investiture of the Holy Archangel Michael[1] or the Book of the Investiture of Michael[2]) is an apocryphal text of the New Testament. It is an Old Nubian-language text, purportedly written by John the Apostle, which describes the importance of Michael, an archangel, in Christianity, as well as the role of Satan in several biblical events.
