For all the promises of God in him are yea, and in him Amen, unto the glory of God by us.

AD 400
Paul means that the work of the Father and the Son is one. When the Father gives the Spirit, the Son gives him too, because the Holy Spirit comes from both of them. He is thinking of the Trinity here because he has been speaking about the perfecting of mankind. The whole sum of perfection is found in the Trinity. Commentary on Paul’s Epistles.
