I then went on to describe the various divine offices and ministries after the similitude of the palace of an earthly king, which I fully described; and I added:
"Can we suppose that God the Lord of lords and King of kings, is content with a single order of servants? We speak of an archangel because there are other angels of whom he is chief: and so there would be nothing said of Principalities, Powers and Dominions unless it were implied that there were others of inferior rank."
But, if he thinks that I became a follower of Origen because I mentioned in my exposition these advancements and honours, these ascents and descents, increasings and diminishings; I must point out that to say, as Origen does, that Angels and Cherubim and Seraphim are turned into demons and men, is a very different thing from saying that the Angels themselves have various offices allotted to them, -- a doctrine which is not repugnant to that of the church. Just as among men there are various degrees of dignity distinguished by the different kinds of work, as the bishop, the presbyter and the other Ecclesiastical grades have each their own order, while yet all are men; so we may believe that, while they all retain the dignity of Angels, there are various degrees of eminence among them, without imagining that angels are changed into men, and that men are new-made into angels.
