Andreas of Caesarea : The new dimension to the commandment is that now the light has come into the world, our Lord Jesus, because of whom the power of the devil has passed away. — CATENA Bede : Which is true in him and in you, etc. Behold here is the new, for darkness pertains to the old man and the light truly to the new man. Finally, the Apostle Paul says: Put off the old man and put on the new one (Eph. IV); and again: You were once darkness, but now you are light in the Lord (Eph. V). — Commentary on the Catholic Epistles Clement of Alexandria ((as quoted by Cassiodorus)) : "This is the commandment; for the darkness" of perversion, that is, "has passed away, and, lo, the true light has already shone," - that is, through faith, through knowledge, through the Covenant working in men, through prepared judgments. — From the Latin Translation of Cassiodorus Hilary of Arles : The commandment is true in him because he loved us so much that he died for us, and it will be true in us also if we love one another. — INTRODUCTORY COMMENTARY ON 1 JOHN Ishodad of Merv : By "commandment" John means the revelation of the dispensation. It cannot be called new with respect to God, but from the human point of view it was a mystery hidden in the Creator from the beginning. — COMMENTARIES Oecumenius : "Again, I write a new commandment to you, which is true in Him and in you: because the darkness is passing away, and the true light is already shining." Thus, concerning the commandment of love for one's neighbor, which has long been established for both Jews and Greeks, John says: "Besides the old commandment that you heard about loving your neighbor, I am writing a new commandment to you: which is true in him who made you familiar with God, and in you who have communion with Him. For he himself says: "I have come as a light into the world," (Jn. 12:46) and the true light, according to his word, now shines (Jn. 1:9); furthermore, in the light, darkness cannot stand (Jn. 1:5): let the true light of love shine from now on (Matt. 5:16), with genuine affection towards your brother, and let the darkness of hatred pass away, that is, let it depart, let it perish." The phrase means passing away also, as the blessed Paul, where he says, "For the form of this world is passing away." (1 Cor. 7:31) — In another manner concerning this: "I write a new commandment to you." This commandment is new, in that the commandment of Moses was not universal, but distinct according to those who were of the same kin or tribe, urging to love only friends (Lev. 19:18), while having hatred for enemies, as it says: "You shall love your friend and hate your enemy." (Matt. 5:43) The command of the Lord and His apostles, however, is very new, instructing: "Love your enemies and do good to those who hate you," (Luke 6:27) holding to natural existence, and not to that natural affection which clings to wicked men given over to evil arts out of malice. — Commentary on 1 John Tertullian : Nay, but this whole world is the one house of all; in which world it is more the heathen, who is found in darkness, whom the grace of God enlightens, than the Christian, who is already in God's light. Finally, it is one "straying" which is ascribed to the ewe and the drachma: (and this is an evidence in my favour); for if the parables had been composed with a view to a Christian sinner, after the loss of his faith, a second loss and restoration of them would have been noted. — On Modesty
