Michael or Mîkhā'ēl in Biblical and post Biblical lore, ranks as the greatest of all angels. His name means “who is like God” and he was worshipped as a god by the Chaldeans.
According to tradition, he is chief of the order of virtues, chief of archangels, prince of the presence, angel of repentance, righteousness, mercy, and sanctification; also ruler of the 4th Heaven and the leader of God's army. His mystery name is Sabbathiel.
Legend speaks of Michael having assisted four other great angels – Gabriel, Uriel, Raphael, Metatron – in the burial of Moses.
His feast day is September 29 (Michaelmas).
