Michael 23 was hegoumenos of the monastery of Hagios Petros; in 787 he attended the Second Council of Nikaia (the Seventh Ecumenical Council) and is attested at the fourth session, on 1 October 787, where he subscribed the statements read out from the Fathers in support of the veneration of icons: Mansi XIII 152 (Μιχαὴλ ἡγούμενος τοῦ ἁγίου Πέτρου). He probably attended other sessions of the Council also; see Gregorios 45.
