Thus the connection of the Father in the Son, and of the Son in the Paraclete, produces three coherent Persons, who are yet distinct One from Another. These three are one [thing], not one [Person], as it is said, 'I and my Father are One,' in respect of unity of substance not singularity of number.

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.

The fact is certain because it is impossible.

[Hermogenes] despises God's law in his painting, maintains repeated marriages [almost certainly a reference to remarrying after divorce or perhaps even widowhood, which Tertullian, who became a Montanist, opposed], alleges the law of God in defense of lust [likely same reference], and yet despises it in respect of his art.

What is nobler than to tread under foot the gods of the nations, to exorcise evil spirits, to perform cures, to seek divine revelations, and to live to God? These are the pleasures - these are the spectacles - that befit Christian men.

Indeed it is better to postpone, lest either we complete too little by hurrying, or wander too long in completing it.
