We read of Michael, the archangel (Jude 9; 1 Thess. 4:16); angels,
authorities, and powers--which are supposedly ranks and orders of
angels (1 Pet. 3:22; Col. 1:16). In the Apocryphal books we find
a hierarchy with seven archangels, including Michael, Gabriel,
Raphael, Uriel. The fact that but one archangel is mentioned in
the Scriptures proves that its doctrine of angels was not derived,
as some supposed, from Babylonian and Persian sources, for there
we find seven archangels instead of one.
