In style and vocabulary, there are so many similarities between I John and the Gospel of John that no one can doubt that they are at least from the same tradition. Indeed, 1 John makes sense if it is understood as having been written in a period following the appearance of the Gospel, when the struggle with the synagogue and "the Jews" was no longer a major issue. Instead, a division between the Johannine Christians had arisen, caused by different views of Jesus. Both groups accepted the gospel's profession of faith that the Word was God, but they disagreed about the importance of what the Word had done in the flesh, i.e., how he had "walked. One group felt that his actions set a moral standard to be followed; the other argued that simply believing in the Word was all that mattered, and that what Christians did was no more important than what Jesus did.

1. General Analysis of the Message
   1. Prologue (1: 1-4)

      This mini-prologue is less clear than the one in the Gospel and emphasizes the "we", i.e. the bearers of the tradition and the interpreters of the Johannine school who preserve the testimony of the beloved disciple. Therefore, the "beginning" refers to the beginning of Jesus' ministry. And the object of the eyewitness account is "the word of life," a life that was revealed in and through Jesus. The reader can participate in this life, and thus be in communion with the living God. This communion is the root of Christian joy and an essential component of the Johannine community.

   2. Part One: God is light and we must walk in light (1: 5 - 3: 10)

      The message opens on a world divided between light and darkness. Walking in the light and acting in the truth guarantees fellowship with each other and "with him," for the blood of Jesus cleanses from sin. Unlike false propagandists who refuse to acknowledge their misdeeds as sins, true Christians publicly acknowledge or confess their sins, for which Jesus is the atonement. To claim to be without sin is to make God a liar. The author reminds us that if we sin, we have a paraclete with the Father, "Jesus Christ the righteous." The letter continues with the observance of the commandments and thus the perfecting of God's love. Specifically, the commandment to love one's Christian neighbor ("brother") is emphasized. Although this is an old commandment known to the Johannine Christians "from the beginning" when they converted to Christ, it is new in the sense that it has yet to be fully implemented in a world freed by Jesus from the power of darkness.

      The author addresses the recipients under different names: "Children" can be seen as a general form of address for all Johannine Christians, including "fathers" (who have been Christians for longer and therefore know the One who is from the beginning) and "young people" (newer Christians who have fought against the Evil One and have overcome him). He passionately denounces the world and its attractions: the lust of the senses, the attraction of the eyes and a pretentious lifestyle. A struggle is waged against the agent of the Evil One, the antichrist. This struggle is already underway in opposition to the author and the true Johannine Christians who are the false teachers (who are the antichrists) and their followers who have left the community. Satan is the liar par excellence, and his mark is on all those who deny that Jesus is the Christ. Blessed are the "children" of the community who have received the anointing of the Holy One. This anointing that came at the beginning, when they became Christians, makes it unnecessary to be taught by such teachers, for true believers have both eternal life and the truth in which they dwell.

      The author now emphasizes the parousia and the return of Jesus at the end of time. Although Jesus is already present to all believers who do what is right, the fullness of union is only possible with his final return. Present union with Jesus allows us to face with confidence his return in judgment (either in death or at the end of the world). This assurance is justified because "we are children of God because the seed of God has begotten us. The children of God and the children of the devil are clearly distinct because the former act in righteousness and love their brothers and sisters.

   3. Part Two: Walk as the children of the God who has loved us in Christ

      The message now focuses on love. Using the example of Cain, the author argues that hatred is a form of murder. In contrast, Christ gave his life for us, and so we should be willing to give our lives for our brothers and sisters. In particular, the specific requirement that those with means must help a "brother in need" suggests that the secessionists were the wealthiest members of the community and therefore should be assimilated into the world. Then comes the call to love: "We must believe in the name of the Son of God, Jesus Christ, and love one another as he has commanded us"; the very points of faith and practice in which the false propagandists were deficient.

      There is a test to discern false prophets who claim to be led by the Spirit: "by their fruits you will know them." There is a spirit of God and a spirit of antichrist, and anyone led by the Spirit listens to the representatives of the community. Of course, one can guess that the secessionists direct the same polemic against the author and his followers; for them there is the spirit of deception.

      Abruptly, the author returns to the theme of mutual love with the resounding proclamation, "God is love". We know this not because we have taken the initiative to love God, but because God took the initiative to send his only Son into the world so that we might have life and sins might be atoned for. All of this leads to the proclamation, "No one has ever seen God, but if we love one another, God dwells in us and God's love is brought to perfection in us." To be practical, the writer gives a test: All those who claim to love God while hating their brothers and sisters (Christians) are liars.

      The author now writes that whoever believes that Jesus is the Christ is begotten of God and will overcome the world, a victory won by faith. He mentions three witnesses, i.e. the Spirit, water and blood, an obscure reference that seems to echo John 19:34 where the blood flowing from Christ's pierced side is mixed with water, the sign of the Spirit. This emphasis on the salvific witness borne by Jesus' shed blood is probably a corrective to secessionists who placed all the emphasis on understanding Jesus' salvific action at the moment of his baptism when the Spirit descended. The later sacramental use of the passage in a liturgical context uncovers references to baptism and the eucharist as a witness to faith in Christ. This second part with the affirmation that the acceptance of such divine witness leads to belief in the Son of God and the possession of (eternal) life.

   4. Conclusion (5: 13-21)

      The author clarifies the purpose of his letter: "That you may know that you have this eternal life, you who believe in the name of the Son of God." This motive is linked to the invitation to pray for sinners to receive life, for these prayers will be heard. There is, however, one important exception: The author does not exhort to pray for those who commit a "mortal sin," apparently the sin of joining the secession, which was a form of apostasy.

      The author returns to his dualistic vision where God and those begotten by God are opposed to the Evil One and the world that is within his reach. And the guarantee of knowing God and the truth is the recognition of the coming of the Son of God. The letter ends with a clear affirmation of the divinity of Christ. The impassioned closing cry, "Little children, beware of idols," brings to mind the secessionists, for their false Christology is a form of idolatry.

2. Composition
   1. Author

      It has traditionally been assumed that the same author composed the Gospel of John and the three epistles (or letters) of John. The similarities shared by 1 John and John are numerous. Indeed, many statements in 1 John could be put on the lips of the Johannine Jesus, and there would be no way to distinguish them from the words actually attributed to him in John. Yet there are also some surprising differences:

      • The Prologue of 1 John does not emphasize the incarnation of the personified Word, as does the Prologue of John. Rather, it testifies to the word (message) of life that was seen, heard and felt, the human career of Jesus

      • 1 John attributes to God characteristics that the Gospel attributes to Jesus, e.g. God is light, God gives the commandment to love one another

      • The epistolary emphasis is less on the Spirit as a person, and the evangelical term "Paraclete" is never used to designate the Spirit; it is Christ who is the paraclete

      • There is a warning that not every spirit is the Spirit of Truth or the Spirit of God, and therefore spirits must be tested

      • The emphasis is on the final eschatology or parousia as a time to give an account of one's Christian life

      • As far as vocabulary is concerned, the parallels in the Dead Sea Scroll are even closer in 1 John than in the Gospel.

      Some of these differences make the epistles seem more primitive than the Gospel, but they may reflect the author's claim to present the Gospel as it was "from the beginning." Overall, they suggest that the same person may not have written the epistles and the gospel. Some would therefore distinguish at least four figures in the Johannine school of writers: the beloved disciple (who was the source of the tradition), the evangelist who wrote the body of the Gospel, the presbyter who wrote the epistles, and the editor of the Gospel.

   2. Dating and Occasion of Writing

      1 John was known to Polycarp and Justin and therefore certainly existed before the year 150. Most scholars believe that the Johannine epistles were written in the decade after the evangelist wrote the body of the Gospel (circa 90) but before the final writing of the Gospel (which may have been contemporary with 2 John, just after 100). What particularly differentiates I and 2 John from the Gospel is the change in focus. "The Jews," who are the main opponents of the Gospel, are absent; all the attention is focused on deceivers who have withdrawn from the community, and who, in so doing, have shown a lack of love for their former brothers and sisters. Such "antichrists" would seduce people in several ways:

      1. Faith. Secessionists deny the importance of Jesus' human career by not confessing him as the Christ come in the flesh. They probably thought that salvation came only from the entrance of the Son of God into the world, so that Jesus' historical activity had no salvific or exemplary significance. In particular, they seem to have overlooked Jesus' bloody death as an act of love and atonement, a point the author emphasizes.

      2. Morals. Secessionists do not recognize that they have sinned. Perhaps this moral stance is related to their Christology if, having denied the importance of what the Son of God did in the flesh after the incarnation, they denied the importance of what they themselves did in the flesh after becoming children of God by faith. The children of God, the author insists, must walk in purity and love, just as Jesus, the Son of God, did.

      3. Spirit. Secessionist leaders claim to be teachers and even prophets, led by the Spirit. The author denies the need for teachers and warns against false prophets and asks to test the spirits to see if they are of God. There is a Spirit of deception that leads the antichrists, and a Spirit of truth that leads the author and his followers.

      Who are these secessionists? They have been identified with a number of known heretics of the early second century, such as the Docetists (who denied that Christ was truly human), or Cerinthus (who believed that Christ, a spiritual being, descended upon Jesus, a normal man, after baptism and withdrew from him before the crucifixion), or the Gnostics (who considered the world and the flesh an illusion). But these heresies may be later descendants of the error encountered in 1 John. This error is likely an exaggeration by Johannine Christians of certain features of the fourth gospel in which the pre-existent Son of God saves people by his very entrance into the world as light, and people are saved by faith in Jesus. The gospel gives little ethical teaching, except the command to love one another. And the Paraclete (advocate) or Spirit of truth comes to dwell in every believer, guiding him or her into all truth.

      The author of 1 and 2 John must therefore rectify the situation and defend the true Gospel, testifying to the tradition handed down by the beloved disciple, recalling the importance of the way Jesus lived (walked) in the flesh and died for sins.

   3. Genre and Structure

      Let's start with the genre. 1 John has none of the characteristics of the epistolary format. It is probably a written exhortation interpreting the main themes of the fourth gospel in the light of secessionist propaganda that had some plausibility and continued to attract followers. It was presumably circulated in the main center of Johannine Christianity (Ephesus?) where the gospel was written and where the author lived.

      As for the structure, the author offers no clear indication of a plan. He is repetitive, and uses hinge verses that belong to both what precedes and what follows. Those who believe that 1 John is an interpretation of the fourth Gospel favor a bipartite division that corresponds to the gospel division. A Prologue (1:1-4) comments on the hymn that is the Prologue of the Gospel, and a Conclusion (5:13-21) takes up the theme of the Conclusion of the basic Gospel (Jn 20:30-31). The two main parts of the epistle are delimited by the statement "this is the message (gospel)" in 1:5 and 3:11. The first part defines the gospel as "God is light" and emphasizes the obligation to walk in the light. The second part defines the gospel as a call to love and presents Jesus as the example of love for his Christian brother and sister.

3. Issues and Problems for Reflections
   1. Should this epistle be printed in semi-poetic format? A number of translators have done so, because the Johannine author's Greek can be divided into lines of relatively similar length that correspond to each other in a rough rhythm.

   2. 1 John's description of the world has sometimes been criticized as being too negative, as if the author forgot that God created the world and saw that it was good. In any case, 1 John describes the world of God's creation after it has been spoiled by sin. Furthermore, it may be necessary to remind an "anything goes" generation that the condemnation of sensual lust and concupiscence cannot be considered merely "Victorian" but has deep roots in the Judeo-Christian tradition.

   3. Some find almost a contradiction in 1 John's insistence on love and refusal to pray for those who commit mortal sin. It is not arrogance to recognize evil and those who do it; but Christians should be careful before deciding that such people are radically evil in themselves and cannot be prayed for.
