Enoch predicted that "the demons and the spirits of the angelic apostates would turn into idolatry all the elements, all the adornment of the universe, and all things contained in the heaven, the sea, and the earth, that they might be consecrated as God in opposition to God." All things, therefore, does human error worship, except the Founder of all himself. The images of those things are idols; the consecration of the images is idolatry.
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[T]he Father, the Son, and the Holy Ghost [are] three ... not in condition, but in degree; not in substance, but in form; not in power, but in aspect; yet of one substance, and of one condition, and of one power, inasmuch as He is one God, from whom these degrees and forms and aspects are reckoned, under the name of the Father, and of the Son, and of the Holy Ghost.
