44. Let us now consider whether as we read that the sacrament of baptism in the Name of Christ was complete, so, too, when the Holy Spirit alone is named, anything is wanting to the completeness of the mystery. Let us follow out the argument that he who has named One has signified the Trinity. If you name Christ, you imply both God the Father by Whom the Son was anointed, and the Son Himself Who was anointed, and the Holy Spirit with Whom He was anointed. For it is written: “This Jesus of Nazareth, Whom God anointed with the Holy Spirit.” And if you name the Father, you denote equally His Son and the Spirit of His mouth, if, that is, you apprehend it in your heart. And if you speak of the Spirit, you name also God the Father, from Whom the Spirit proceeds, and the Son, inasmuch as He is also the Spirit of the Son.
