We must at the outset hold fast the meaning of the Greek scripture, which has afflatus, not spirit. Some interpreters of the Greek, without reflecting on the difference of the words, and careless about their exact meaning, put spirit for afflatus; they thus afford to heretics an opportunity of tarnishing the Spirit of God, that is to say, God Himself, with default.
Tertullian
The Five Books Against Marcion, Book II
Chapter IX
