140. Therefore the Spirit is not a creature, but the Creator, and He Who is Creator is certainly not a creature. And because He is not a creature, without doubt He is the Creator Who produces all things together with the Father and the Son. But if He be the Creator, certainly the Apostle, by saying in condemnation of the Gentiles, “Who served the creature rather than the Creator, Who is God blessed for ever,” Rom. i. 25. and by warning men, as I said above, that the Holy Spirit is to be served, both showed Him to be the Creator, and because He is the Creator demonstrated that He ought to be called God. Which he also sums up in the Epistle written to the Hebrews, saying: “For He that created all things is God.” Heb. iii. 4. Let them, therefore, either say what it is which has been created without the Father, Son, and Holy Spirit, or let them confess that the Spirit also is of one Godhead with the Father and the Son.
