Augustine of Hippo : "Little children, let no man seduce you. He that doeth righteousness is righteous, as He is righteous." What, on hearing that we are "righteous as He is righteous," are we to think ourselves equal with God? Ye must know what means that "as:" thus he said a while ago, "Purifieth himself even as He is pure." Then is our purity like and equal to the purity of God, and our righteousness to God's righteousness? Who can say this? But the word "as," is not always wont to be used in the sense of equality. As, for example, if, having seen this large church, a person should wish to build a smaller church, but with the same relative dimensions: as, for example, if this be one measure in width and two measures in length, he too should build his church one measure in width and two measures in length: in that case one sees that he has built it "as" this is built. But this church has, say, a hundred cubits in length, the other thirty: it is at once "as" this, and yet unequal. Ye see that this "as" is not always referred to parity and equality. For example, see what a difference there is between the face of a man and its image from a mirror: there is a face in the image, a face in the body: the image exists in imitation, the body in reality. And what do we say? Why, "as" there are eyes here, so also there; "as" ears here, so ears also there. The thing is different, but the "as" is said of the resemblance. Well then, we also have in us the image of God; but not that which the Son equal with the Father hath: yet except we also, according to our measure, were "as" He, we should in no respect be said to be like Him. "He purifieth us," then, "even as He is pure:" but He is pure from eternity, we pure by faith. We are "righteous even as He is righteous;" but He is so in His immutable perpetuity, we righteous by believing on One we do not see, that so we may one day see Him. Even when our righteousness shall be perfect, when we shall be equal to the angels, not even then shall it be equalled with Him. How far then is it from Him now, when not even then it shall be equal! — Ten Homilies on 1 John 4 Bede : Little children, let no one deceive you. Whoever practices righteousness is righteous, etc. And above: He purifies himself, it says, just as He is pure. Not that our righteousness or holiness can be equal to the divine, since it is written: There is none holy like the Lord (1 Samuel 2), but just as there is much difference between the face of a man and the image in a mirror, because the image is in imitation, the body in reality, and yet, just as here are eyes, so also there; yet the matter differs, but just as it pertains to likeness, so also we indeed have the image of God, but not the one which the Son, equal to the Father, has. For we also, according to our measure, if we were not in some way like Him, would by no means be called similar. Therefore he sanctifies us, just as He is holy. But He is holy in eternity, we are holy by faith. We are righteous, just as He is righteous. But He in the immutable perpetuity itself, we righteous by believing in Him whom we do not see, so that we may someday see. — Commentary on the Catholic Epistles Hilary of Arles : Let no one deceive you by saying that there is nothing wrong with sin. The devil has sinned all along because there is no truth in him. He is the ultimate deceiver. — INTRODUCTORY COMMENTARY ON 1 JOHN Ignatius of Antioch : None of these things is hid from you, if ye perfectly possess that faith and love towards Christ Jesus which are the beginning and the end of life. For the beginning is faith, and the end is love. Now these two, being inseparably connected together, are of God, while all other things which are requisite for a holy life follow after them. No man [truly] making a profession of faith sinneth; nor does he that possesses love hate any one. The tree is made manifest by its fruit; so those that profess themselves to be Christians shall be recognised by their conduct. For there is not now a demand for mere profession, but that a man be found continuing in the power of faith to the end. — Epistle of Ignatius to the Ephesians Oecumenius : Little children, let no one deceive you. Whoever practices righteousness is righteous, just as He is righteous. But he proceeds more firmly with these words, saying: "let no one deceive you." For it cannot be otherwise than this: He who does righteousness knows the Righteous One, and is righteous, just as He is, that is, God. — Commentary on 1 John
