Investiture of the Archangel Michael
The Investiture of the Archangel Michael, also known as the Book of the Investiture of the Holy Archangel Michael and the Book of the Investiture of Michael, is a text of New Testament apocrypha. It is pseudepigrapha, purportedly written by John the Apostle, and part of a genre of "apostolic memoirs" popular in Coptic literature of the period. The work describes the importance of Michael, an archangel, in Christianity, as well as the role of Satan in several biblical events. Manuscripts exist in the Coptic language, and fragments exist in Old Nubian and Medieval Greek.
