138. In like manner, then, the Spirit is said to hear from the Father, and to glorify the Son. To glorify, because the Holy Spirit taught us that the Son is the Image of the invisible God, and the brightness of His glory, and the impress of His substance. The Spirit also spoke in the patriarchs and the prophets, and, lastly, the apostles began then to be more perfect after that they had received the Holy Spirit. There is therefore no separation of the divine power and grace, for although “there are diversities of gifts, yet it is the same Spirit; and diversities of ministrations, yet the same Lord; and diversities of operations, yet the same God Who worketh all in all.” There are diversities of offices, not severances of the Trinity.
