The New Testament rarely speaks of angels, and makes only two references to archangels: Michael in Jude 1.9 and I Thessalonians 4:16, where the "voice of an archangel" will be heard at the return of Christ. Contrary to popular belief, Gabriel is never called 'archangel' in the Gospels.
In later Christian tradition, however, there are three archangels: Michael, Gabriel, and usually Raphael; sometimes Uriel is given as a fourth. Eastern Orthodox tradition mentions "Seven Archangels". Uriel is included, and the other three are most often cited as Selaphiel, Jegudiel, and Barachiel.
