Bede : Little children, keep yourselves from idols. You who have known the true God, in whom you have eternal life, keep yourselves from the doctrines of heretics, which lead to eternal death, because, like those who make idols in place of God, they change the glory of the incorruptible God into the likeness of corruptible things with perverse teachings (Rom. I). Keep yourselves from love of money, which is the service of idols. Be careful not to prefer any worldly allurements over the love of the Creator. For this too will be counted among idols, so that having the care and diligence for truth alone, you may deserve to rejoice endlessly in its vision. For the world passes away, and its desire. But whoever does the will of the Lord remains forever (1 John II). — Commentary on the Catholic Epistles Didymus the Blind : Why is it that after everything else which he has said to his hearers during the course of his letter, John should keep this warning about idols to the very end? In my opinion it is because here he is addressing the church in general. There must have been many in that assembly who were former idolaters, and he adds this caution for their benefit. — CATENA Hilary of Arles : The letter ends as it began, with an admonition to worship the one true God alone. Everything else that John says is contained in this one golden rule. — INTRODUCTORY COMMENTARY ON 1 JOHN Oecumenius : Little children, keep yourselves from idols. Amen. "keep yourself from idols." Some have questioned: If John writes this to the perfect, why does he now command them to beware of idols? We therefore say that because he wrote to the whole Church, which was not made up of a select people, but there were also some among them who were less affected. Therefore, he commands all these, looking at their slippery nature. — Commentary on 1 John Tertullian : John did not tell us to keep away from worship, but from idols, that is, from their very likeness. For it is wrong for you, who are created in the image of the living God, to become the image of an idol and a dead man. — ON THE CROWN 5.10 Tertullian : Even an earthly serpent sucks in men at some distance with its breath. Going still further, John says, "My little children, keep yourselves from idols," -not now from idolatry, as if from the service of it, but from idols-that is, from any resemblance to them: for it is an unworthy thing that you, the image of the living God, should become the likeness of an idol and a dead man. — De Corona
