Friend, Foe, or Faux? Discerning True and False Believers

by Brannon Pate May 28, 2026

Discerning Between the Three Characters of 1 John

1 John is all about fellowship with God, which is possible through Jesus Christ and life in the Spirit (1:1–4). The Apostle John describes life in the Spirit through the abiding “anointing” (2:27) and abiding “seed” (3:9) of God before speaking explicitly about the abiding Holy Spirit in chapter 4. Although fellowship with God is the primary focus of the letter, we must not overlook John’s desire: “what we have seen and heard we proclaim to you also, so that you too may have fellowship with us; and indeed our fellowship is with the Father, and with His Son Jesus Christ” (1:3, emphasis added). John’s purpose is that others may have fellowship with him and the church. Thus, all who are in fellowship with God are in fellowship with one another.

This framework is important for understanding the letter because as John writes to establish faith and assurance (1 John 5:13), he addresses three characters and the conflict that arises from them: friends, foes, and fauxs. The “friends” are those who are truly in fellowship with God and God’s people. The “foes” are those who are in fellowship with the world and the devil. Finally, and most challenging, are the fauxs—imposters of the faith—who appear to be in fellowship with God but truly belong to the world and the devil. The main test in 1 John, then, is not distinguishing between friends and foes, but friends and fauxs.

To illustrate, the greatest threat in war is not the place outside the gates where the enemy is gathered, but sabotage, spies, and traitors from within. Think of the Trojan horse and how the guise of a ceasefire resulted in the fall of the city from within after decades of standing strong. The fellowship of the church is to be a secure fellowship, but often, fauxs find their place within and bring destruction. Fauxs are hard to detect because they come just as everyone else: with a profession of faith, baptism, and so on. They continue in the fellowship and discipleship of the church for a time. Yet, as many pastors and laypeople can attest, they have witnessed the destruction fauxs bring on the church. In this letter, John provides insight for discerning fauxs so that appropriate action can be taken in love and truth to preserve the faith and fellowship of the church before ruin occurs.

Revealing Friends

From 1 John 1:5–5:12, John sets forth various tests which differentiate between the three characters. Friends are known by confessing their sins (1:5–2:2), living in obedience to Christ’s commands (2:3–11), persevering in the faith and fellowship of the Church (2:18–27; 4:1–6; 5:5–12), and practicing righteousness (2:28–3:10). Furthermore, obedience and righteousness are characterized by love for one another, which is a dominant emphasis in the letter (2:7–11; 3:10–24; 4:4–5:5). John uses the word “ought” to describe how Christians are expected to live like Christ (2:6) through a love of sacrifice (3:16) and forgiveness (4:10–11). In this way, the friends enjoy the Life (1:2), Light (1:5), and Love (4:8) of God.

Revealing Foes

In contrast, the foes are completely against the friends. They are opposed to the Father (2:15–17), the truth of Jesus Christ (4:1–6), the church (3:1b, 13), and righteousness and love (3:4–10). They are of the world and the devil, living in sin and darkness, and filled with hatred and murder—especially towards Christians. The foes of God and His people are given no assurance but are warned of coming destruction (3:8; contrast with believers in 3:18–24 and 4:15–21 who have confidence). The contrast between friends and foes is set in black-and-white terms, creating a sharp distinction between the two groups. Discerning between friends and foes is easy!

Revealing Fauxs

However, the challenge arises with the fauxs. What was black-and-white becomes gray and more dangerous. The friends are a loving people, and sometimes their love can interfere with the safeguards of truth. So, the friends often lack discernment, which matters not just for their own sake, but for one another—their fellow friends. Nevertheless, John exposes the fauxs as those who “say,” but what they “do” contradicts their claims: They claim to have fellowship with God, but walk in darkness characterized by unconfessed, unrepentant sin (1:5–10); they claim to know Christ, but then disobey His commands (2:3–6); they claim to be in the Light characterized by truth, but they hate their brothers/friends in Christ (2:9–11).

Exposing the fauxs, John declares they are liars, self-deceived, still in darkness/sins, of the devil and the world, do not have eternal life, and are headed for judgment (1:6, 2:4, 2:11, 2:15–17, 2:22, 3:7–10, 3:15, 4:3–5, 4:8, 4:20). They are antichrists and followers of antichrist (2:18–19); they are false prophets and the followers of false prophets (4:1–6). They remain in their sins and darkness and are headed toward judgment. Despite their claim to be friends and to be in fellowship with God, they are given no assurance of eternal life. Instead, they are allotted a portion with the foes!

Despite the presence of fauxs, true friends stand out as those who know, repent, walk, love, obey, practice righteousness, and persevere with Christ and His Church. This multifaceted understanding of faith is consistent throughout 1 John and reflects Jesus’ own teaching (John 13–17). When John says in 1 John 5:13, “these things I have written to you,” he means the faith presented from 1:5–5:12. This faith characterizes those who believe and are assured of eternal life. They are set in contrast to both those who completely reject God and those who say they are of God but are not.

A Call to Discernment

To conclude, distinguishing between friends, foes, and fauxs is as crucial in our day as the first century. If God’s people lack discernment, their faith and fellowship will be compromised by fauxs even as they seek to stand in truth and love against their foes. As we rest assured that Christ and His Church will prevail (Matt. 16:18), we recognize this victory is accomplished through the Church’s merciful discernment in the Spirit (cf. Matt. 18:15–35).
