23. For if we say that the Holy Spirit is included amongst all things, certainly when we read that the Spirit searches the deep things of God, 1 Cor. ii. 10. we deny that God the Father is over all. For since the Spirit is of God, and is the Spirit of His mouth, how can we say that the Holy Spirit is included amongst all things, seeing that God, Whose is the Spirit, is over all, possessing certainly fulness of perfection and perfect power.
