Whether the distinction of hierarchies and orders comes from the angelic nature?

❌ Objection 1 : It would seem that the distinction of hierarchies and of orders is not from the nature of the angels. For hierarchy is "a sacred principality," and Dionysius places in its definition that it "approaches a resemblance to God, as far as may be" (Coel. Hier. iii). But sanctity and resemblance to God is in the angels by grace, and not by nature. Therefore the distinction of hierarchies and orders in the angels is by grace, and not by nature.

❌ Objection 2 : Further, the Seraphim are called "burning" or "kindling," as Dionysius says (Coel. Hier. vii). This belongs to charity which comes not from nature but from grace; for "it is poured forth in our hearts by the Holy Ghost Who is given to us" (Rm. 5:5): "which is said not only of holy men, but also of the holy angels," as Augustine says (De Civ. Dei xii). Therefore the angelic orders are not from nature, but from grace.

❌ Objection 3 : Further, the ecclesiastical hierarchy is copied from the heavenly. But the orders among men are not from nature, but by the gift of grace; for it is not a natural gift for one to be a bishop, and another a priest, and another a deacon. Therefore neither in the angels are the orders from nature, but from grace only.
