Consider the great authority he gave the holy apostles, how he declared them praiseworthy, and how he decorated them with the highest honors.… “He that hears you,” He says, “hears Me, and he that rejects you, rejects Me; and he that rejects Me, rejects Him that sent Me.” O what great honor! What incomparable dignities! O what a gift worthy of God! Although men, the children of earth, He clothes them with a godlike glory. He entrusts His words to them that they who resist anything or venture to reject them may be condemned. When they are rejected, He assures them that He suffers this. Then again, He shows that the guilt of this wickedness, as being committed against Him, rises up to God the Father. See with the eyes of the mind how vast a height He raises the sin committed by men in rejecting the saints! What a wall He builds around them! How great security He contrives for them! He makes them such as must be feared and in every way plainly provides for their being uninjured.… Christ gives those who love instruction the assurance that whatever is said concerning Him by the holy apostles or evangelists is to be received necessarily without any doubt and to be crowned with the words of truth. He who hears them, hears Christ. For the blessed Paul also said, “You desire proof that Christ is speaking in me.” Christ Himself somewhere also said to the holy disciples, “For it is not you that speak, but the Spirit of your Father that speaks in you.” Christ speaks in them by the consubstantial Spirit. If it is true, and plainly it is, that they speak by Christ, how can they err? He affirms that he who does not hear them, does not hear Christ, and that he who rejects them rejects Christ, and with him the Father.
Cyril of Alexandria, Commentary on Luke Homily 63
“I was looking at Satan, who fell like lightning from the heavens.” It was not that he was actually in the heavens. He was not in them when he said, “I will place my throne above the stars,” but he fell from his greatness and his dominion. “I was looking at Satan, who fell like lightning from the heavens.” He did not fall from heaven, because lightning does not fall from heaven, since the clouds create it. Why then did he say “from the heavens”? This was because it was as though it was from the heavens, as if lightning which comes suddenly. In one second, Satan fell beneath the victory of the cross. Ordinary people were anointed and sent out by reason of their mission and were highly successful in a second, through miracles of healing those in pain, sickness and evil spirits. It was affirmed that Satan suddenly fell from his dominion, like lightning from the clouds. Just as lightning goes out and does not return to its place, so too did Satan fall and did not again have control over his dominion. “Behold, I am giving you dominion.”
