John Chrysostom

(Hom. v. c. 2. 3) But if you say that the prophet spoke this of the Father, and that Paul applied it to the Son, it comes to the same thing. For he would not have mentioned that as applicable to the Son, unless he fully considered that the Father and the Son were of equal dignity. If again thou dream that in the preposition by any subjection is implied, why does Paul use t of the Father? as, God is faith ful, by Whom ye were called into the fellowship of His Son; (1 Cor. 1:9) and again, Paul an Apostle by the will of God. (2 Cor. 1:1)
