Verses 6-12. - The section takes a new turn; the test of the Christian life furnished by the witness of the life itself. This witness is that of the Spirit (verse 6), identical with that of God (verse 9), and possessed by every believer (verse 10). Few passages of Scripture have produced such a mass of widely divergent interpretation. Verse 6. - This (Son of God) is he who came by water and blood, Jesus Christ. This may be regarded as one of the main propositions of the Epistle - that the eternal Son of God is identical with the historic Person, Jesus. Of the water and the blood widely differing interpretations have been given. It would be tedious and unprofitable to enumerate them. Our estimate of John 19:34, "the most perplexing incident in the Gospel," will probably influence our interpretation of this "the most perplexing passage in the Epistle." Not that we have here any direct reference to the piercing of Christ's side, and its results. Yet both passages teach similar spiritual truths, viz. the ideas which underlie the two sacraments, and teach them by reference to facts in the life and death of Jesus Christ. But the facts are not the same in each case. It is difficult to believe that this passage contains any definite and immediate allusion to John 19:34. Why in that case the marked change of order, "water and blood" instead of "blood and water"? And if it be thought that this is explained by saying that the one is "the ideal, mystical, sacramental, subjective order," the ether "the historical and objective order," and that "the first is appropriately adopted in the Epistle, the second in the Gospel," we are not at the end of our difficulties. If St. John is here referring to the effusions from Christ's dead body, what can be the meaning of "not in water only, but in water and blood"? It was the water, not the blood, that was specially astonishing. And "in" in this case seems a strange expression to use. We should have expected rather, "not shedding blood only, but blood and water." Moreover, how can blood and water flowing from the Lord's body be spoken of his "coming through water and blood"? The simplest interpretation is that which refers ὕδωρ to the baptism of water to which he himself submitted, and which he enjoined upon his disciples, and αῖμα to the baptism of blood to which he himself submitted, and which raised the baptism of water from a sign into a sacrament. John came baptizing in water only ἐν ὕδατι βαπτίζων (John 1:31, 33). Jesus came baptizing in water and blood, i.e., in water which washed away sin through the efficacy of his blood. This interpretation explains the marked change of preposition. Jesus effected his work through the baptisms of water and blood; and it is by baptism in these elements that he comes to his followers. Moreover, this interpretation harmonizes with the polemical purpose of the Epistle, viz. to confute the errors of Cerinthus. Cerinthus taught that the Divine Logos or Christ descended upon Jesus at the baptism, and departed again when Jesus was arrested; so that a mere man was born of Mary, and a mere man suffered on the cross. St. John assures us that there was no such severance. The Divine Son Jesus Christ came not by water only at his baptism, but by blood also at his death. Besides these two abiding witnesses, there is yet a third still more convincing. And there is the Spirit that beareth witness (to the Divinity of Christ); because the Spirit is the truth. There can be no higher testimony than that of the truth itself (John 14:17; John 15:26; John 16:13). It is surprising that any one should propose to translate, "The Spirit is that which is witnessing that the Spirit is the truth." What has this to do with the context?
5:6-8 We are inwardly and outwardly defiled; inwardly, by the power and pollution of sin in our nature. For our cleansing there is in and by Christ Jesus, the washing of regeneration and the renewing of the Holy Ghost. Some think that the two sacraments are here meant: baptism with water, as the outward sign of regeneration, and purifying from the pollution of sin by the Holy Spirit; and the Lord's supper, as the outward sign of the shedding Christ's blood, and the receiving him by faith for pardon and justification. Both these ways of cleansing were represented in the old ceremonial sacrifices and cleansings. This water and blood include all that is necessary to our salvation. By the water, our souls are washed and purified for heaven and the habitation of saints in light. By the blood, we are justified, reconciled, and presented righteous to God. By the blood, the curse of the law being satisfied, the purifying Spirit is obtained for the internal cleansing of our natures. The water, as well as the blood, came out of the side of the sacrificed Redeemer. He loved the church, and gave himself for it, that he might sanctify and cleanse it with the washing of water by the word; that he might present it to himself a glorious church, Eph 5:25-27. This was done in and by the Spirit of God, according to the Saviour's declaration. He is the Spirit of God, and cannot lie. Three had borne witness to these doctrines concerning the person and the salvation of Christ. The Father, repeatedly, by a voice from heaven declared that Jesus was his beloved Son. The Word declared that He and the Father were One, and that whoever had seen him had seen the Father. And the Holy Ghost, who descended from heaven and rested on Christ at his baptism; who had borne witness to Him by all the prophets; and gave testimony to his resurrection and mediatorial office, by the gift of miraculous powers to the apostles. But whether this passage be cited or not, the doctrine of the Trinity in Unity stands equally firm and certain. To the doctrine taught by the apostles, respecting the person and salvation of Christ, there were three testimonies. 1. The Holy Spirit. We come into the world with a corrupt, carnal disposition, which is enmity to God. This being done away by the regeneration and new-creating of souls by the Holy Spirit, is a testimony to the Saviour. 2. The water: this sets forth the Saviour's purity and purifying power. The actual and active purity and holiness of his disciples are represented by baptism. 3. The blood which he shed: and this was our ransom, this testifies for Jesus Christ; it sealed up and finished the sacrifices of the Old Testament. The benefits procured by his blood, prove that he is the Saviour of the world. No wonder if he that rejects this evidence is judged a blasphemer of the Spirit of God. These three witnesses are for one and the same purpose; they agree in one and the same thing.
This is he that came by water and blood, even Jesus Christ,.... By "water" is not meant the ablutions or washings of the ceremonial law; Christ came not by these, but to make an end of them; his blood, which cleanseth from all sin, being the antitype, and so the fulfilling end of them: nor the purity of his nature, life, and conversation; though he came into the world that holy thing which is called the Son of God; and was holy in his nature, and harmless in his life, and did no sin, and so was fit to be a sacrifice for the sins of others: nor does it intend the washing and cleansing of his people from their sins; this is what he came to do, and has done, and not what he came by: but the ordinance of water baptism is designed; and though Christ did not come baptizing with water, he having a greater baptism to administer, yet that he might be made manifest, John came baptizing in that way; and Christ, as the Son of God, came, or was made manifest by John as such, at the waters of Jordan, and at his baptism; there he was declared to be the Son of God by his Father's voice from heaven:
not by water only; he did not come by water only, as Moses did, who was drawn out of it, and therefore so called; or as John, who came administering water baptism externally only:
but by water and blood; by "blood" as well as water; by which is meant, not the blood of bulls and goats; Christ came to put an end unto, and lay aside the shedding of that blood; but his own blood is intended, and not reconciliation and atonement for the sins of his people, which was what he came to do, and has done, and not what he came by: but the sense is, that as at baptism, so at his sufferings and death, he was made manifest to be the Son of God; as he was to the centurion and others, that were with him, when they observed the earthquake, and the things that were done; and at his from the dead he was declared to be the Son of God with power: and this might be seen in the cleansing and atoning virtue of his blood, which is owing to his being the Son of God. There may be here an allusion to the water and blood which came out of his side, when pierced on the cross, which this Apostle John was an eyewitness of. Some copies add here, and in the former clause, "and by the Spirit"; as the Alexandrian copy, three of Beza's copies, and the Ethiopic version: but it seems unnecessary, since it follows,
and it is the Spirit that beareth witness; by which may be meant, either the Gospel, which is the Spirit that gives life, and is so called, because by it the Spirit of God, in his gifts and graces, is received, and which is a testimony of the person, as well as of the offices, and grace of Christ; or rather those miraculous works which Christ did by the Spirit, to which he often appeals, as witnesses of his divine sonship, and equality with the Father, as well as of his being the true Messiah; or else the Holy Spirit, who bore testimony to Christ, by his descent on him at his baptism, and upon his apostles at the day of Pentecost, and by attending, succeeding, and confirming the Gospel, which is the testimony of him; and he is elsewhere, as well as here, and in the context, spoken of as a witness of Christ, Acts 5:32;
because the Spirit is truth; he is the Spirit of truth, and truth itself; he is essentially truth; his testimony is most true, and firmly to be believed. The Vulgate Latin version reads, "because Christ is the truth".
