The Feast of Holy Michael and All Angels—commonly called Michaelmas—celebrates the ministry of angels as messengers and servants of God, with particular honor to Michael, the archangel who according to Daniel, Jude, and Revelation leads the heavenly host in battle against the powers of evil. The feast encompasses all the angelic orders—cherubim, seraphim, archangels, and angels—and affirms the Church's belief that the visible and invisible worlds are united in the worship and service of God.
