Athanasius of Alexandria : If the blessed Peter speak of the Divine Word also, as sent to the children of Israel by Jesus Christ, it is not necessary to understand that the Word is one and Christ another, but that they were one and the same by reason of the uniting which took place in His divine and loving condescension and becoming man. And even if He be considered in two ways, still it is without any division of the Word, as when the inspired John says, 'And the Word became flesh, and dwelt among us.' ...And how can Christ be called a mere man? on the contrary, being made one with the Word, He is with reason called Christ and Son of God, the prophet having long since loudly and clearly ascribed the Father's subsistence to Him, and said, 'And I will send My Son Christ,' and in the Jordan, 'This is My Well-beloved Son.' For when He had fulfilled His promise, He shewed, as was suitable, that He was He whom He said He had sent. — Four Discourses Against the Arians, Discourse 4, Sections 31 & 33 John Chrysostom : And see now how he advances. In his first sermon, he but slightly hinted at the resurrection, and Christ's sitting in heaven; but here he also speaks of His visible advent. "And He shall send Jesus the Christ ordained (for you), Whom the heaven must (i.e. must of necessity) receive, until the times of the restitution of all things." The reason why He does not now come is clear. "Which God hath spoken," he continues, "by the mouth of His holy prophets since the world began." — Homily on Acts 9 John Chrysostom : Then to prove that Christ is the cause of the days of refreshing, he says, "And He shall send Jesus Christ, which before was for you ordained." He said not, "That your sin may be blotted out," but, "your sins;" for he hints at that sin also. "He shall send." And whence? "Whom the heaven must receive." Still "receive?" And why not simply, Whom the heaven hath received? This, as if discoursing of old times: so, he says, it is divinely ordered, so it is settled: not a word yet of His eternal subsistence. — Homily on Acts 9
