Scripture and ancient Jewish literature identify powerful angels as archangels (archangelos/ ἀρχάγγελος). Michael is called an archangel in Jude 9. He contends against Satan. In Revelation 12:7-9 John depicts Michael along with an army of angels fighting against Satan and his angels. In relation to the second coming of Jesus, Paul mentions an archangel's voice but no name in 1 Thessalonians 4:16.
