74. Good, then, is the Spirit, but good, not as though acquiring but as imparting goodness. For the Holy Spirit does not receive from creatures but is received; as also He is not sanctified but sanctifies; for the creature is sanctified, but the Holy Spirit sanctifies. In which matter, though the word is used in common, there is a difference in the nature. For both the man who receives and God Who gives sanctity are called holy, as we read: “Be ye holy, for I am holy.” Lev. xix. 2. Now sanctification and corruption cannot share the same nature, and therefore the grace of the Holy Spirit and the creature cannot be of one substance.
