Whether the grades of the orders are properly assigned?

Objections

Objection 1 : It would seem that the grades of the orders are not properly assigned. For the order of prelates is the highest. But the names of "Dominations," "Principalities," and "Powers" of themselves imply prelacy. Therefore these orders ought not to be supreme.
Objection 2 : Further, the nearer an order is to God, the higher it is. But the order of "Thrones" is the nearest to God; for nothing is nearer to the sitter than the seat. Therefore the order of the "Thrones" is the highest.
Objection 3 : Further, knowledge comes before love, and intellect is higher than will. Therefore the order of "Cherubim" seems to be higher than the "Seraphim."
Objection 4 : Further, Gregory (Hom. xxiv in Evang.) places the "Principalities" above the "Powers." These therefore are not placed immediately above the Archangels, as Dionysius says (Coel. Hier. ix).
