Gregory the Dialogist : We must consider what it means that Mark says: He sits at the right hand of God; while Stephen says: I see the heavens opened, and the Son of man standing at the right hand of God. What does it mean that Mark testifies he is sitting, while Stephen testifies that he saw him standing? But you know, brothers, that sitting belongs to one who judges, while standing belongs to one who fights or helps. Therefore, because our Redeemer, having been taken up into heaven, both now judges all things and at the end comes as judge of all, Mark describes him as sitting after his assumption, because after the glory of his Ascension he will be seen as judge at the end. But Stephen, placed in the labor of struggle, saw him standing whom he had as helper, because in order that Stephen might overcome on earth the unbelief of his persecutors, his grace fought for him from heaven. — Forty Gospel Homilies, Homily 29 John Chrysostom : He mentions the cause of his angelic appearance: "But he, being full of the Holy Ghost, looked up steadfastly into heaven, and saw the glory of God, and Jesus standing on the right hand of God." And in this manner He appeared to him: that, were it but so, the Jews might receive Him: for since the idea of His sitting at the right hand of God was offensive to them, for the present he brings forward only what relates to His Resurrection. This is the reason also why his face was glorified. For God, being merciful, desired to make their machinations the means of recalling them unto Himself. — Homily on Acts 18 John Chrysostom : And when he said, "I see the heavens opened, they stopped their ears, and ran upon him with one accord." And yet in what respect are these things deserving of accusation? "Upon him," the man who has wrought such miracles, the man who has prevailed over all in speech, the man who can hold such discourse! As if they had got the very thing they wanted, they straightway give full scope to their rage. — Homily on Acts 18 Tertullian : He is seen by Stephen, at his martyrdom by stoning, still sitting at the right hand of God [Acts 7:55] where He will continue to sit, until the Father shall make His enemies His footstool. [Hebrews 10:12-13] He will come again on the clouds of heaven, just as He appeared when He ascended into heaven. [Acts 1:11] — Against Praxeas, Chapter 30 Tertullian : "He sitteth at the Father's right hand " -not the Father at His own. He is seen by Stephen, at his martyrdom by stoning, still sitting at the right hand of God where He will continue to sit, until the Father shall make His enemies His footstool. — Against Praxeas Theodoret of Cyrus : The divine nature is invisible, but the thrice blessed Stephen said that he saw the Lord, so even after the resurrection the Lord's body is a body, and it was seen by the victorious Stephen, since the divine nature cannot be seen. — DIALOGUE (DEMONSTRATIONS BY SYLLOGISMS) 11
