Hilary of Poitiers : We cannot be ignorant that the Lord Jesus Christ rose again from the dead, and sits at the right hand of God, for we have also the witness of the Apostle, According to the working of the strength of His might, which He wrought in Christ, when He raised Him from the dead, and made Him to sit at His right hand in the heavenly places above all rule and authority and power and dominion, and every name that is named not only in this world but also in that which is to come, and put all things in subjection under His feet. The language of the Apostle, as befits the power of God, speaks of the future as already past: for that which is to be wrought by the completion of time already exists in Christ, in Whom is all fulness, and `future' refers only to the temporal order of the Dispensation, not to a new development. Thus, God has put all things under His feet, though they are still to be subjected. By their subjection, conceived as already past, is expressed the immutable power of Christ: by their subjection, as future, is signified their consummation at the end of the ages as the result of the fulness of time. — ON THE TRINITY 11.31 Jerome : He demonstrates the power of God through a human image. It is not that a material throne is set up and God the Father is physically seated on it and has the Son seated above with him. Rather he communicates with this metaphor because we could not understand his role as incomparable governor and judge except in our own terms.… Being on the right or left of God is to be understood as meaning that saints are on his right but sinners on his left. … The very word sits denotes the power of kingship, through which God confers benefits on those above whom he is seated. He has reined them in and has them in his service, guiding those who had previously strayed. — Commentary on Ephesians 1:21 John Chrysostom : Seest thou how great things He hath wrought? He hath raised up Christ. Is this a small thing? But look again. He hath set Him at His right hand. And shall any language then be able to represent this? Him that is of the earth, more mute than the fishes, and made the sport of devils, He hath in a moment raised up on high. Truly this is indeed the "exceeding greatness of His power." And behold, whither He hath raised Him. "In the heavenly places;" He hath made Him far above all created nature, far above all rule and authority. — Homily on Ephesians 3 Theodoret of Cyrus : It is clear that he says all this of Christ in his humanity. This is what inspires wonder. For it would hardly be remarkable to say that God sits by God if fellowship in power is a corollary of their identity of nature as Father and Son. But that the human nature assumed from us should partake of the same honor as the one who assumed him, so that no difference in worship is apparent, so that the invisible Godhead is worshiped through the visible human nature—this exceeds all wonder! The holy apostle is overwhelmed. He first sings of the exceeding greatness of his power. Then he speaks of the working of his mighty strength. Then he looks for whatever he can say that might point to the extraordinary nature of his exaltation. — Interpretation of the Epistle to the Ephesians 1.20
