The 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.
TertullianIf we refuse our homage to statues and frigid images, the very counterpart of their dead originals, with which hawks, and mice, and spiders are so well acquainted, does it not merit praise instead of penalty [Christians were punished for not worshiping Roman gods] that we have rejected what we have come to see is error? We cannot surely be made out to injure those whom we are certain are nonentities. What does not exist is in its nonexistence secure from suffering.
Tertullian
