The Son of God died; it is by all means to be believed because it is absurd. And he was buried and rose again; the fact is certain, because it is impossible.
TertullianThe angels as the guardians of men are set over men as instructors and monitors. This shows the relationship that is to exist between them. Man's attitude is to be one of obedience and subjection. He is to follow the lead of the angels, and consequently some reverence is already implied in the very relationship that exists between man and angel.
Tertullian
