3. That which we have seen. He now repeats the third time the words, seen and heard, that nothing might be wanting as to the real certainty of his doctrine. And it ought to be carefully noticed, that the heralds of the Gospel chosen by Christ were those who were fit and faithful witnesses of all those things which they were to declare. He also testifies of the feeling of their heart, for he says that he was moved by no other reason to write except to invite those to whom he was writing to the participation of an inestimable good. It hence appears how much care he had for their salvation; which served not a little to induce them to believe; for extremely ungrateful we must be, if we refuse to hear him who wishes to communicate to us a part of that happiness which he has obtained.

He also sets forth the fruit received from the Gospel, even that we are united thereby to God, and to his Son Christ in whom is found the chief good. It was necessary for him to add this second clause, not only that he might represent the doctrine of the Gospel as precious and lovely, but that he might also show that he wished them to be his associates for no other end but to lead them to God, so that they might be all one in him. For the ungodly have also a mutual union between themselves, but it is without God, nay, in order to alienate themselves more and more from God, which is the extreme of all evils. It is, indeed, as it has been stated, our only true happiness, to be received into God's favor, so that we may be really united to him in Christ; of which John speaks in the seventeenth chapter of his gospel.

In short, John declares, that as the apostles were adopted by Christ as brethren, that being gathered into one body, they might together be united to God, so he does the same with other colleagues; though many, they are yet made partakers of this holy and blessed union.

4. That your joy may be full. By full joy, he expresses more clearly the complete and perfect happiness which we obtain through the Gospel; at the same time he reminds the faithful where they ought to fix all their affections. True is that saying,

"Where your treasure is, there will be your heart also."
(Matthew 6:21.)

Whosoever, then, really perceives what fellowship with God is, will be satisfied with it alone, and will no more burn with desires for other things.

"The Lord is my cup," says David, "and my heritage; the lines have fallen for me on an excellent lot." (Psalm 16:5, 6.)

In the same manner does Paul declare that all things were deemed by him as dung, in comparison with Christ alone. (Philippians 3:8.) He, therefore, has at length made a proficiency in the Gospel, who esteems himself happy in having communion with God, and acquiesces in that alone; and thus he prefers it to the whole world, so that he is ready for its sake to relinquish all other things.

5. This then is the message, or promise. I do not disapprove of the rendering of the old interpreter, "This is the annunciation," or message; for though ejpaggeli>a means for the most part a promise, yet, as John speaks here generally of the testimony before mentioned, the context seems to require the other meaning, except you were to give this explanation, "The promise which we bring to you, includes this, or has this condition annexed to it." Thus, the meaning of the Apostle would become evident to us. ¹ For his object here was not to include the whole doctrine of the Gospel, but to shew that if we desire to enjoy Christ and his blessings, it is required of us to be conformed to God in righteousness and holiness. Paul says the same thing in the second chapter of the Epistle to Titus, "Appeared has the saving grace of God to all, that denying ungodliness and worldly lusts, we may live soberly and righteously and holily in this world;" except that here he says metaphorically, that we are to walk in the light, because God is light.

But he calls God light, and says that he is in the light; such expressions are not to be too strictly taken. Why Satan is called the prince of darkness is sufficiently evident. When, therefore, God on the other hand is called the Father of light, and also light, we first understand that there is nothing in him but what is bright, pure, and unalloyed; and, secondly, that he makes all things so manifest by his brightness, that he suffers nothing vicious or perverted, no spots or filth, no hypocrisy or fraud, to lie hid. Then the sum of what is said is, that since there is no union between light and darkness, there is a separation between us and God as long as we walk in darkness; and that the fellowship which he mentions, cannot exist except we also become pure and holy.

In him is no darkness at all. This mode of speaking is commonly used by John, to amplify what he has affirmed by a contrary negation. Then, the meaning is, that God is such a light, that no darkness belongs to him. It hence follows, that he hates an evil conscience, pollution, and wickedness, and everything that pertains to darkness.

6. If we say. It is, indeed, an argument from what is inconsistent, when he concludes that they are alienated from God, who walk in darkness. This doctrine, however, depends on a higher principle, that God sanctifies all who are his. For it is not a naked precept that he gives, which requires that our life should be holy; but he rather shews that the grace of Christ serves for this end to dissipate darkness, and to kindle in us the light of God; as though he had said, "What God communicates to us is not a vain fiction; for it is necessary that the power and effect of this fellowship should shine forth in our life; otherwise the possession of the gospel is fallacious." What he adds, and do not the truth, is the same as if he had said, "We do not act truthfully. We do not regard what is true and right." And this mode of speaking, as I have before observed, is frequently used by him.

7. But if we walk in the light. He now says, that the proof of our union with God is certain, if we are conformable to him; not that purity of life conciliates us to God, as the prior cause; but the Apostle means, that our union with God is made evident by the effect, that is, when his purity shines forth in us. And, doubtless, such is the fact; wherever God comes, all things are so imbued with his holiness, that he washes away all filth; for without him we have nothing but filth and darkness. It is hence evident, that no one leads a holy life, except he is united to God.

In saying, We have fellowship one with another, he does not speak simply of men; but he sets God on one side, and us on the other.

It may, however, be asked, "Who among men can so exhibit the light of God in his life, as that this likeness which John requires should exist; for it would be thus necessary, that he should be wholly pure and free from darkness." To this I answer, that expressions of this kind are accommodated to the capacities of men; he is therefore said to be like God, who aspires to his likeness, however distant from it he may as yet be. The example ought not to be otherwise applied than according to this passage. He walks in darkness who is not ruled by the fear of God, and who does not, with a pure conscience, devote himself wholly to God, and seek to promote his glory. Then, on the other hand, he who in sincerity of heart spends his life, yea, every part of it, in the fear and service of God, and faithfully worships him, walks in the light, for he keeps the right way, though he may in many things offend and sigh under the burden of the flesh. Then, integrity of conscience is alone that which distinguishes light from darkness.

And the blood of Jesus Christ. After having taught what is the bond of our union with God, he now shews what fruit flows from it, even that our sins are freely remitted. And this is the blessedness which David describes in the thirty-second Psalm, in order that we may know that we are most miserable until, being renewed by God's Spirit, we serve him with a sincere heart. For who can be imagined more miserable than that man whom God hates and abominates, and over whose head is suspended both the wrath of God and eternal death?

This passage is remarkable; and from it we first learn, that the expiation of Christ, effected by his death, does then properly belong to us, when we, in uprightness of heart, do what is right and just for Christ is no redeemer except to those who turn from iniquity, and lead a new life. If, then, we desire to have God propitious to us, so as to forgive our sins, we ought not to forgive ourselves. In short, remission of sins cannot be separated from repentance, nor can the peace of God be in those hearts, where the fear God does not prevail.

Secondly, this passage shews that the gratuitous pardon of sins is given us not only once, but that it is a benefit perpetually residing in the Church, and daily offered to the faithful. For the Apostle here addresses the faithful; as doubtless no man has ever been, nor ever will be, who can otherwise please God, since all are guilty before him; for however strong a desire there may be in us of acting rightly, we always go haltingly to God. Yet what is half done obtains no approval with God. In the meantime, by new sins we continually separate ourselves, as far as we can, from the grace of God. Thus it is, that all the saints have need of the daily forgiveness of sins; for this alone keeps us in the family of God.

By saying, from all sin, he intimates that we are, on many accounts, guilty before God; so that doubtless there is no one who has not many vices. But he shews that no sins prevent the godly, and those who fear God, from obtaining his favor. He also points out the manner of obtaining pardon, and the cause of our cleansing, even because Christ expiated our sins by his blood; but he affirms that all the godly are undoubtedly partakers of this cleansing.

The whole of his doctrine has been wickedly perverted by the sophists; for they imagine that pardon of sins is given us, as it were, in baptism. They maintain that there only the blood of Christ avails; and they teach, that after baptism, God is not otherwise reconciled than by satisfactions. They, indeed, leave some part to the blood of Christ; but when they assign merit to works, even in the least degree, they wholly subvert what John teaches here, as to the way of expiating sins, and of being reconciled to God. For these two things can never harmonize together, to be cleansed by the blood of Christ, and to be cleansed by works: for John assigns not the half, but the whole, to the blood of Christ.

The sum of what is said, then, is, that the faithful know of a certainty, that they are accepted by God, because he has been reconciled to them through the sacrifice of the death of Christ. And sacrifice includes cleansing and satisfaction. Hence the power and efficiency of these belong to the blood of Christ alone.

Hereby is disproved and exposed the sacrilegious invention of the Papists as to indulgences; for as though the blood of Christ were not sufficient, they add, as a subsidy to it, the blood and merits of martyrs. At the same time, this blasphemy advances much further among us; for as they say that their keys, by which they hold as shut up the remission of sins, open a treasure made up partly of the blood and merits of martyrs, and partly of the worlds of supererogation, by which any sinner may redeem himself, no remission of sins remains for them but what is derogatory to the blood of Christ; for if their doctrine stands, the blood of Christ does not cleanse us, but comes in, as it were, as a partial aid. Thus consciences are held in suspense, which the Apostle here bids to rely on the blood of Christ.
