The order of superiority among the angels. Considered from the part of God, there is one celestial hierarchy with God in dominion over all the angels, but considered from their part there are three grades of superiority, the lower from the higher differing in perfection and power and where the former are subject to the latter. These subdivisions of the celestial hierarchy are often referred to as choirs.
