Image result for nine orders of angels“We accept nine ranks of angels, because from the testimony of the word of God we know about Angels, Archangels, Powers, Authorities, Principalities, Dominions, Thrones, Cherubim, and Seraphim. Thus, concerning the existence of Angels and Archangels, almost every page of Sacred Scripture testifies; of the Cherubim and Seraphim as is well known, the prophetic books speak often; the Apostle Paul enumerates four other ranks in his Epistle to the Ephesians, saying that God (the Father) placed His Son ‘far above all Principality, and Authority, and Power, and Dominion’ (Eph. 1:21). And in his Epistle to the Colossians he writes, ‘By Him were all things created, that are in heaven, and that are in earth, visible and invisible, whether Thrones, or Dominions, or Principalities, or Powers’ (Col. 1:16). And so, when we join Thrones to these four of which he speaks to the Ephesians, that is, Principalities, Authorities, Powers and Dominions, we have five separate ranks; and when we join to them the Angels, Archangels, Cherubim, and Seraphim, it is clear that there are nine ranks of angels.”
