7. Who, then, can doubt that the Spirit sent the prophets and apostles, since the Son of God says: “The Spirit of the Lord is upon Me.” S. Luke iv. 18. And elsewhere: “I am the First, and I am also for ever, and Mine hand hath founded the earth, and My right hand hath established the heaven; I will call them and they shall stand up together, and shall all be gathered together and shall hear. Who hath declared these things to them? Because I loved thee I performed thy pleasure against Babylon, that the seed of the Chaldæans might be taken away. I have spoken, and I have called, I have brought him and have made his way prosperous. Come unto Me and hear ye this. From the beginning I have not spoken in secret, I was there when those things were done; and now the Lord God hath sent Me and His Spirit.” Isa. xlii. 12 ff. [LXX.]. Who is it Who says: The Lord God hath sent Me and His Spirit, except He Who came from the Father that He might save sinners? And, as you hear, the Spirit sent Him, lest when you hear that the Son sends the Spirit, you should believe the Spirit to be of inferior power.
