For what war should we not be fit and eager, even though unequal in numbers, we who are so willing to be slaughtered-if, according to that discipline of ours, it was not more lawful to be slain than to slay?
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.
