“That which was from the beginning, which we have heard, and which we have seen with our eyes, and our hands have handled, of the Word of life: and the life was manifested, and we have seen, and bear witness, and show unto you that eternal life, which was with the Father, and was manifested unto us: the things which we have seen and heard declare we unto you, that you also may have fellowship with us: and that our fellowship may be with the Father, and with His Son Jesus Christ. And these things write we unto you, that your joy may be full. This then is the message which we have heard of Him, and declare unto you, that God is light, and in Him is no darkness at all. If we say that we have fellowship with Him, and walk in darkness, we lie, and do not the truth: if we walk in the light, as He is in the light, we have fellowship one with another, and the blood of Jesus Christ His Son shall cleanse us from all sin. If we say that we have no sin, we deceive ourselves, and the truth is not in us. If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness. If we say that we have not sinned, we make Him a liar, and His word is not in us. My little children, these things write I unto you, that you sin not. And if any man sin, we have an Advocate with the Father, Jesus Christ the righteous: and He is the propitiation for our sins: not for our's only, but also for the sins of the whole world. And in this we do know Him, if we keep His commandments. He that says he knows Him, and keeps not His commandments, is a liar, and the truth is not in him. But whoso keeps His word, in him verily is the love of God perfected. In this we know that we are in Him, if in Him we be perfect. He that says he abides in Him ought himself also so to walk, even as He walked. Beloved, I write no new commandment unto you, but an old commandment which you had from the beginning. The old commandment is the word which you have heard. Again, a new commandment I write unto you, which thing is true in Him and in you: because the darkness is past, and the true light now shines. He that says he is in the light, and hates his brother, is in darkness even until now. He that loves his brother abides in the light, and there is none occasion of stumbling in him. For he that hates his brother is in darkness, and walks in darkness, and knows not whither he goes, because the darkness has blinded his eyes.”
1. “That which was from the beginning, which we have heard, which we have seen with our eyes, and our hands have handled, of the word of life.” Who is he that with hands does handle the Word, except because “The Word was made flesh, and dwelt in us”? Now this Word which was made flesh that it might be handled, began to be flesh, of the Virgin Mary: but not then began the Word, for the Apostle says, “That which was from the beginning.” See whether his epistle does not bear witness to his gospel, where ye lately heard, “In the beginning was the Word, and the Word was with God.” Perchance, “Concerning the word of life” one may take as a sort of expression concerning Christ, not the very body of Christ which was handled with hands. See what follows: “And the Life was manifested.” Christ therefore is “the word of life.” And whereby manifested? For it was “from the beginning,” only not manifested to men: but it was manifested to angels, who saw it and fed on it as their bread. But what says the Scripture? “Man did eat angels' bread.” Well then “the Life was manifested” in the flesh; because it exhibited in manifestation, that that which can be seen by the heart only, should be seen by the eyes also, that it might heal the hearts. For only by the heart is the Word seen: but the flesh is seen by the bodily eyes also. We had wherewith to see the flesh, but had not wherewith to see the Word: “the Word was made flesh,” which we might see, that so that in us might be healed wherewith we might see the Word.
2. “And we have seen and are witnesses.” Perhaps some of the brethren who are not acquainted with the Greek do not know what the word “witnesses” is in Greek: and yet it is a term much used by all, and had in religious reverence; for what in our tongue we call “witnesses,” in Greek are “martyrs.” Now where is the man that has not heard of martyrs, or where the Christian in whose mouth the name of martyrs dwells not every day and would that it so dwelt in the heart also, that we should imitate the sufferings of the martyrs, not persecute them with our cups! Well then, “We have seen and are witnesses,” is as much as to say, We have seen and are martyrs. For it was for bearing witness of that which they had seen, and bearing witness of that which they had heard from them who had seen, that, while their testimony itself displeased the men against whom it was delivered, the martyrs suffered all that they did suffer. The martyrs are God's witnesses. It pleased God to have men for His witnesses, that men also may have God to be their witness. “We have seen,” says he, “and are witnesses.” Where have they seen? In the manifestation. What means, in the manifestation? In the sun, that is, in this light of day. And how should He be seen in the sun who made the sun, except as “in the sun He has set His tabernacle; and Himself as a bridegroom going forth out of his chamber, exulted as a giant to run His course?” He before the sun, who made the sun, He before the day-star, before all the stars, before all angels, the true Creator, (“for all things were made by Him, and without Him was nothing made,”) that He might be seen by eyes of flesh which see the sun, set His very tabernacle in the sun, that is, showed His flesh in manifestation of this light of day: and that Bridegroom's chamber was the Virgin's womb, because in that virginal womb were joined the two, the Bridegroom and the bride, the Bridegroom the Word, and the bride the flesh; because it is written, “And they two shall be one flesh;” and the Lord says in the Gospel, Therefore they are no more two but one flesh. And Esaias remembers right well that they are two: for speaking in the person of Christ he says, “He has set a mitre upon me as upon a bridegroom, and adorned me with an ornament as a bride.” One seems to speak, yet makes Himself at once Bridegroom and Bride; because “not two, but one flesh:” because “the Word was made flesh, and dwelt in us.” To that flesh the Church is joined, and so there is made the whole Christ, Head and body.
