“"That which was from the beginning; which we have seen with our eyes; which we have heard." Following the Gospel according to John, and in accordance with it, this Epistle also contains the spiritual principle. What therefore he says, "from the beginning," the Presbyter explained to this effect, that the beginning of generation is not separated from the beginning of the Creator. For when he says, "That which was from the beginning," he touches upon the generation without beginning of the Son, who is co-existent with the Father. There was; then, a Word importing an unbeginning eternity; as also the Word itself, that is, the Son of God, who being, by equality of substance, one with the Father, is eternal and uncreate. That He was always the Word, is signified by saying, "In the beginning was the Word." But by the expression, "we have seen with our eyes," he signifies the Lord's presence in the flesh, "and our hands have handled," he says, "of the Word of life." He means not only His flesh, but the virtues of the Son, like the sunbeam which penetrates to the lowest places,-this sunbeam coming in the flesh became palpable to the disciples. It is accordingly related in traditions, that John, touching the outward body itself, sent his hand deep down into it, and that the solidity of the flesh offered no obstacle, but gave way to the hand of the disciple. "And our hands have handled of the Word of life; "that is, He who came in the flesh became capable of being touched.”

“Read the testimony of John: "That which we have seen, which we have heard, which we have looked upon with our eyes, and our hands have handled, of the Word of life." False, of course, and deceptive must have been that testimony, if the witness of our eyes, and ears, and hands be by nature a lie.”
“But the very same apostles testify that they had both seen and "handled" Christ. Now, if Christ is Himself both the Father and the Son, how can He be both the Visible and the Invisible? In order, however, to reconcile this diversity between the Visible and the Invisible, will not some one on the other side argue that the two statements are quite correct: that He was visible indeed in the flesh, but was invisible before His appearance in the flesh; so that He who as the Father was invisible before the flesh, is the same as the Son who was visible in the flesh? If, however, He is the same who was invisible before the incarnation, how comes it that He was actually seen in ancient times before (coming in) the flesh? And by parity of reasoning, if He is the same who was visible after (coming in) the flesh, how happens it that He is now declared to be invisible by the apostles? How, I repeat, can all this be, unless it be that He is one, who anciently was visible only in mystery and enigma, and became more clearly visible by His incarnation, even the Word who was also made flesh; whilst He is another whom no man has seen at any time, being none else than the Father, even Him to whom the Word belongs? Let us, in short, examine who it is whom the apostles saw. "That," says John, "which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life." Now the Word of life became flesh, and was heard, and was seen, and was handled, because He was flesh who, before He came in the flesh, was the "Word in the beginning with God" the Father, and not the Father with the Word.”

“And this species of the divine patience indeed being, as it were, at a distance, may perhaps be esteemed as among "things too high for us; " but what is that which, in a certain way, has been grasped by hand among men openly on the earth? God suffers Himself to be conceived in a mother's womb, and awaits the time for birth; and, when born, bears the delay of growing up; and, when grown up, is not eager to be recognised, but is furthermore contumelious to Himself, and is baptized by His own servant; and repels with words alone the assaults of the tempter; while from being" Lord" He becomes" Master," teaching man to escape death, having been trained to the exercise of the absolute forbearance of offended patience.”

“To God their beauty, to God their youth (is dedicated). With Him they live; with Him they converse; Him they "handle" by day and by night; to the Lord they assign their prayers as dowries; from Him, as oft as they desire it, they receive His approbation as dotal gifts.”
“Did not certain of the disciples turn back from the Lord Himself, When they were offended? Yet the rest did not therefore think that they must turn away from following Him, but because they knew that He was the Word of Life, and was come from God, they continued in His company to the very last, after He had gently inquired of them whether they also would go away.”

“But the writer of the Revelation puts himself forward at once in the very beginning, for he says: "The Revelation of Jesus Christ, which He gave to him to show to His servants quickly; and He sent and signified it by His angel to His servant John, who bare record of the Word of God, and of his testimony, and of all things that he saw." And then he writes also an epistle, in which he says: "John to the seven churches which are in Asia, grace be unto you, and peace." The evangelist, on the other hand, has not prefixed his name even to the catholic epistle; but without any circumlocution, he has commenced at once with the mystery of the divine revelation itself in these terms: "That which was from the beginning, which we have heard, which we have seen with our eyes." And on the ground of such a revelation as that the Lord pronounced Peter blessed, when He said: "Blessed art thou, Simon Bar-jona; for flesh and blood hath not revealed it unto thee, but my Father which is in heaven." For the Gospel and the Epistle agree with each other, and both commence in the same way. For the one opens thus, "In the beginning was the Word;" while the other opens thus, "That which was from the beginning." The one says: "And the Word was made flesh, and dwelt among us; and we beheld His glory, the glory as of the Only-begotten of the Father." The other says the same things, with a slight alteration: "That which we have heard, which we have seen with our eyes, which we have looked upon, and our hands have handled, of the Word of life: and the life was manifested." For these things are introduced by way of prelude, and in opposition, as he has shown in the subsequent parts, to those who deny that the Lord is come in the flesh. For which reason he has also been careful to add these words: "And that which we have seen we testify, and show unto you that eternal life which was with the Father, and was manifested unto us: that which we have seen and heard declare we unto you."”

“Who is he that with hands doth 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 saith, "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 saith 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.”

“The apostle omits his name and character (as also the author to the Hebrews does) either out of humility, or as being willing that the Christian reader should be swayed by the light and weight of the things written rather than by the name that might recommend them. And so he begins, I. With an account or character of the Mediator's person. He is the great subject of the gospel, the foundation and object of our faith and hope, the bond and cement that unite us unto God. He should be well known; and he is represented here, 1. As the Word of life, Jo1 1:1. In the gospel these two are disjoined, and he is called first the Word, Joh 1:1, and afterwards Life, intimating, withal, that he is intellectual life. In him was life, and that life was (efficiently and objectively) the light of men, Joh 1:4. Here both are conjoined: The Word of life, the vital Word. In that he is the Word, it is intimated that he is the Word of some person or other; and that is God, even the Father. He is the Word of God, and so he is intimated to issue from the Father, as truly (though not in the same manner) as a word (or speech, which is a train of words) from a speaker. But he is not a mere vocal word, a bare logos prophorikos, but a vital one: the Word of life, the living word; and thereupon, 1. As eternal life. His duration shows his excellency. He was from eternity; and so is, in scripture-account, necessary, essential, uncreated life. That the apostle speaks of his eternity, parte ante (as they say) and as from everlasting, seems evident in that he speaks of him as he was in and from the beginning; when he was then with the Father, before his manifestation to us, yea, before the making of all things that were make; as Joh 1:2, Joh 1:3. So that he is the eternal, vital, intellectual Word of the eternal living Father. 3. As life manifested (Jo1 1:2), manifested in the flesh, manifested to us. The eternal life would assume mortality, would put on flesh and blood (in the entire human nature), and so dwell among us and converse with us, Joh 1:14. Here were condescension and kindness indeed, that eternal life (a person of eternal essential life) should come to visit mortals, and to procure eternal life for them, and then confer it on them! II. With the evidences and convictive assurances that the apostle and his brethren had of the Mediator's presence and converse in this world. There were sufficient demonstrations of the reality of his abode here, and of the excellency and dignity of his person in the way of his manifestation. The life, the word of life, the eternal life, as such, could not be seen and felt; but the life manifested might be, and was so. The life was clothed with flesh, put on the state and habit of abased human nature, and as such gave sensible proof of its existence and transactions here. The divine life, or Word incarnate, presented and evinced itself to the very senses of the apostles. As, 1. To their ears: That which we have heard, Jo1 1:1, Jo1 1:3. The life assumed a mouth and tongue, that he might utter words of life. The apostles not only heard of him, but they heard him himself. Above three years might they attend his ministry, be auditors of his public sermons and private expositions (for he expounded them in his house), and be charmed with the words of him who spoke as never man spoke before or since. The divine word would employ the ear, and the ear should be devoted to the word of life. And it was meet that those who were to be his representatives and imitators to the world should be personally acquainted with his ministrations. 2. To their eyes: That which we have seen with our eyes, Jo1 1:1-3. The Word would become visible, would not only be heard, but seen, seen publicly, privately, at a distance and at nearest approach, which may be intimated in the expression, with our eyes - with all the use and exercise that we could make of our eyes. We saw him in his life and ministry, saw him in his transfiguration on the mount, hanging, bleeding, dying, and dead, upon the cross, and we saw him after his return from the grave and resurrection from the dead. His apostles must be eye-witnesses as well as ear-witnesses of him. Wherefore, of these men that have accompanied with us all the time that the Lord Jesus went in and out among us, beginning from the baptism of John, must one be ordained to be a witness with us of his resurrection, Act 1:21, Act 1:22. And we were eye-witnesses of his majesty, Pe2 1:16. 3. To their internal sense, to the eyes of their mind; for so (possibly) may the next clause be interpreted: Which we have looked upon. This may be distinguished from the foregoing perception, seeing with the eyes; and may be the same with what the apostle says in his gospel (Joh 1:14), And we beheld - etheasametha, his glory, the glory as of the only-begotten of the Father. The word is not applied to the immediate object of the eye, but to that which was rationally collected from what they saw. "What we have well discerned, contemplated, and viewed, what we have well known of this Word of life, we report to you." The senses are to be the informers of the mind. 4. To their hands and sense of feeling: And our hands have handled (touched and felt) of the Word of life. This surely refers to the full conviction our Lord afforded his apostles of the truth, reality, solidity, and organization of his body, after his resurrection from the dead. When he showed them his hands and his side, it is probable that he gave them leave to touch him; at least, he knew of Thomas's unbelief, and his professed resolution too not to believe, till he had found and felt the places and signatures of the wounds by which he died. Accordingly at the next congress he called Thomas, in the presence of the rest, to satisfy the very curiosity of his unbelief. And probably others of them did so too. Our hands have handled of the Word of life. The invisible life and Word was no despiser of the testimony of sense. Sense, in its place and sphere, is a means that God has appointed, and the Lord Christ has employed, for our information. Our Lord took care to satisfy (as far as might be) all the senses of his apostles, that they might be the more authentic witnesses of him to the world. Those that apply all this to the hearing of the gospel lose the variety of sensations here mentioned, and the propriety of the expressions, as well as the reason of their inculcation and repetition here: That which we have seen and heard declare we unto you, Jo1 1:3. The apostles could not be deceived in such long and various exercise of their sense. Sense must minister to reason and judgment; and reason and judgment must minister to the reception of the Lord Jesus Christ and his gospel. The rejection of the Christian revelation is at last resolved into the rejection of sense itself. He upbraided them with their unbelief and hardness of heart, because they believed not those who had seen him after he had risen, Mar 16:14. III. With a solemn assertion and attestation of these grounds and evidences of the Christian truth and doctrine. The apostles publish these assurances for our satisfaction: We bear witness, and show unto you, Jo1 1:2. That which we have seen and heard declare we unto you, Jo1 1:3. It became the apostles to open to the disciples the evidence by which they were led, the reasons by which they were constrained to proclaim and propagate the Christian doctrine in the world. Wisdom and integrity obliged them to demonstrate that it was not either private fancy or a cunningly-devised fable that they presented to the world. Evident truth would open their mouths, and force a public profession. We cannot but speak the things which we have seen and heard, Act 4:20. It concerned the disciples to be well assured of the truth of the institution they had embraced. They should see the evidences of their holy religion. It fears not the light, nor the most judicious examination. It is able to afford rational conviction and solid persuasion of mind and conscience. I would that you knew what great conflict (or concern of mind) I have for you, and for those at Laodicea, and for as many as have not seen my face in the flesh, that their hearts might be knit together in love, and unto all riches of full assurance of understanding, to the acknowledgment of the mystery of God, even of the Father, and of Christ, Col 2:1, Col 2:2. IV. With the reason of the apostle's exhibiting and asserting this summary of sacred faith, and this breviate of evidence attending it. This reason is twofold: - 1. That the believers of it may be advanced to the same happiness with them (with the apostles themselves): That which we have seen and heard declare we unto you, that you may have fellowship with us, Jo1 1:3. The apostle means not personal fellowship nor consociation in the same church-administrations, but such as is consistent with personal distance from each other. It is communion with heaven, and in blessings that come thence and tend thither. "This we declare and testify, that you may share with us in our privileges and happiness." Gospel spirits (or those that are made happy by gospel grace) would fain have others happy too. We see, also, there is a fellowship or communion that runs through the whole church of God. There may be some personal distinctions and peculiarities, but there is a communion (or common participation of privilege and dignity) belonging to all saints, from the highest apostle to the lowest believer. As there is the same precious faith, there are the same precious promises dignifying and crowning that faith and the same precious blessings and glories enriching and filling those promises. Now that believers may be ambitious of this communion, that they may be instigated to retain and hold fast the faith that is the means of such communion, that the apostles also may manifest their love to the disciples in assisting them to the same communion with themselves, they indicate what it is and where it is: And truly our fellowship (or communion) is with the Father and his Son Jesus Christ. We have communion with the Father, and with the Son of the Father (as Jo2 1:3, he is most emphatically styled) in our happy relation to them, in our receiving heavenly blessings from them, and in our spiritual converse with them. We have now such supernatural conversation with God and the Lord Christ as is an earnest and foretaste of our everlasting abode with them, and enjoyment of them, in the heavenly glory. See to what the gospel revelation tends - to advance us far above sin and earth and to carry us to blessed communion with the Father and the Son. See for what end the eternal life was made flesh - that he might advance us to eternal life in communion with the Father and himself. See how far those live beneath the dignity, use, and end of the Christian faith and institution, who have not spiritual blessed communion with the Father and his Son Jesus Christ. 2. That believers may be enlarged and advanced in holy joy: And these things write we unto you that your joy may be full, Jo1 1:4. The gospel dispensation is not properly a dispensation of fear, sorrow, and dread, but of peace and joy. Terror and astonishment may well attend mount Sinai, but exultation and joy mount Zion, where appears the eternal Word, the eternal life, manifested in our flesh. The mystery of the Christian religion is directly calculated for the joy of mortals. It should be joy to us that the eternal Son should come to seek and save us, that he has made a full atonement for our sins, that he has conquered sin and death and hell, that he lives as our Intercessor and Advocate with the Father, and that he will come again to perfect and glorify his persevering believers. And therefore those live beneath the use and end of the Christian revelation who are not filled with spiritual joy. Believers should rejoice in their happy relation to God, as his sons and heirs, his beloved and adopted, - in their happy relation to the Son of the Father, as being members of his beloved body, and coheirs with himself, - in the pardon of their sins, the sanctification of their natures, the adoption of their persons, and the prospect of grace and glory that will be revealed at the return of their Lord and head from heaven. Were they confirmed in their holy faith, how would they rejoice! The disciples were filled with joy, and with the Holy Ghost, Act 13:52.”

“That which was from the beginning,.... By which is meant not the Gospel, as if the apostle's design was to assert the antiquity of that, and clear it from the charge of novelty; for though that is called the word, and the word of life, and is the Spirit which gives life, and is the means of quickening dead sinners, and brings the report of eternal life and salvation by Christ, yet the seeing of it with bodily eyes, and handling it with corporeal hands, do not agree with that; but Jesus Christ is here intended, who in his divine nature was, really existed as a divine person, as the everlasting Jehovah, the eternal I AM, which is, and was, and is to come, and existed "from the beginning"; not from the beginning of the preaching of the Gospel by John only, for he was before the Gospel was preached, being the first preacher of it himself, and before John was; yea, before the prophets, before Abraham, and before Adam, and before all creatures, from the beginning of time, and of the creation of the world, being the Maker of all things, even from everlasting; for otherwise he could not have been set up in an office capacity so early, or God's elect be chosen in him before the foundation of the world, and they have grace and blessings given them in him before the world began, or an everlasting covenant be made with him; see Joh 1:1; which we have heard; this, with what follows, proves him to be truly and really man; for when the Word was made flesh, and dwelt among men, the apostles heard, and saw, and handled him; they not only heard a voice from heaven, declaring him to be the Son of God, but they often heard him speak himself, both in private conversation with them, and in his public ministry; they heard his many excellent discourses on the mount, and elsewhere, and those that were particularly delivered to them a little before his death; and blessed were they on this account, Mat 13:16; which we have seen with our eyes: with the eyes of the body, with their own, and not another's; and they saw him in human nature, and the common actions of life he did, as eating, drinking, walking, &c. and his many miracles; they saw him raise the dead, cleanse the lepers, restore sight to the blind, cause the lame to walk, the dumb to speak, and the deaf to hear; and they saw him transfigured on the mount. John was one that was present at that time, and saw his glory, as he also was when he hung upon the cross, and saw him bleeding, gasping, and dying there; they saw him after his resurrection from the dead, he showed himself to them alive, and was seen of them forty days; they saw him go up to heaven, and a cloud receiving him out of their sight: which we have looked upon; wistly and intently, once and again, and a thousand times, and with the utmost pleasure and delight; and knew him perfectly well, and were able to describe exactly his person, stature, features, and the lineaments of his body: and our hands have handled of the Word of life; as Peter did when Jesus caught him by the hand on the water, when he was just ready to sink; and as this apostle did, when he leaned on his bosom; and as Thomas did, even after his resurrection, when he thrust his hand into his side; and as all the apostles were called upon to see and handle him, that it was he himself, and not a spirit, which has not flesh and bones as he had. Now as this is said of Christ, the Word of life, who is so called, because he has life in himself, as God, as the Mediator, and as man, and is the author of life, natural, spiritual, and eternal, it must be understood as he, the Word, is made manifest in the flesh; for he, as the Word, or as a divine person, or as considered in his divine nature, is not to be seen nor handled: this therefore is spoken of the Word, or of the person of Christ, God-man, with respect to his human nature, as united to the Logos, or Word of God; and so is a proof of the truth and reality of his human nature, by several of the senses.”

“The first two verses and part of the third have a great conformity with the beginning of St. John’s gospel. The construction is somewhat obscure, unless we observe that the second verse is to be taken by way of a parenthesis, and the sense is not complete till these words, we declare to you, &c. The whole may be expressed in this literal paraphrase: We declare and preach to you the eternal and always living word, which was from the [1] beginning, (for this word which was with the Father from eternity, hath appeared, [2] and manifested himself to us, when he took upon him our human nature, and was made flesh). This word I say, incarnate, we have seen with our eyes, we have heard him preach his gospel, we have touched his true body with our hands, as we witness and declare to you, that you may have fellowship with us, and be made partakers of the graces which God came from heaven to bestow upon mankind, to make us his adoptive sons and heirs of heaven.

“That which was from the beginning. In nature, or in the true being of the Godhead. Which we have heard, through the law and the prophets. Which we have seen, coming perceptibly as man. Which we have looked upon, perceiving the Divinity in the man. And our hands have handled, of the Word of life: not by chance agreeing with him who was seen in the flesh, but with much handling bringing forward the Scriptures as testimony concerning the Word himself. What one has seen he can announce to others; what he has at some time perfectly beheld, he cannot unfold in words.”
