Is this person a Christian? Discerning and Judging Others’ Spiritual State: A Biblical Perspective

In navigating interpersonal relationships within religious communities, particularly Christianity, questions often arise regarding the discernment of someone else’s spiritual state. How does one determine if another person is genuinely a Christian? What does the Bible advise about judging others’ spirituality? This essay aims to explore these complex questions from a biblical and theological perspective.

To address the first question, the New Testament provides some insights. In Matthew 7:16–20, Jesus says, “You will recognize them by their fruits,” indicating that a person’s actions and attitudes can reveal their spiritual condition. In the context of Christianity, “fruits” may be understood as living according to the teachings of Christ, displaying love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control, as outlined in Galatians 5:22–23. In essence, Christian faith, according to the New Testament, is not merely about public professions of faith but is primarily evidenced by Christ-like behavior.

John, in his first epistle (1 John 4:1–3), provides further criteria, emphasizing the importance of Christ-centered belief. He writes, “Every spirit that acknowledges that Jesus Christ has come in the flesh is from God.” This accentuates the centrality of acknowledging Jesus Christ as the foundation of Christian faith.

However, while these criteria provide guidance, they are not foolproof, and the Bible urges caution in attempting to discern others’ spiritual state. Only God, who “searches the heart and tests the mind” (Jeremiah 17:10), can truly know a person’s spiritual condition. Christians are cautioned against assuming this divine prerogative.

This brings us to the second question: What does the Bible say about judging others’ spirituality? The most direct statement on this issue comes from Jesus himself in Matthew 7:1: “Do not judge, or you too will be judged.” This does not mean that Christians should suspend all discernment but rather warns against a critical or condemning attitude towards others.

In Romans 14, the Apostle Paul advises the early Christians not to judge each other over disputable matters of faith and practice. He underscores the principle that each believer is accountable to God (Romans 14:12) and warns against causing others to stumble through judgment (Romans 14:13).

Nevertheless, the Bible also indicates places for rightful judgment or discernment, primarily concerning matters of church discipline (Matthew 18:15–17, 1 Corinthians 5) or identifying false teachers (Matthew 7:15–20, 1 John 4:1). These are specific situations requiring discernment to maintain the spiritual health and doctrinal purity of the community, and they should be approached with humility, love, and a desire for restoration.

In conclusion, while the Bible offers criteria for identifying the marks of Christian faith — Christ-centered belief and the display of spiritual “fruits” — it also warns against the human tendency to judge others critically. It is essential to remember that the ultimate judge of all hearts is God alone. As followers of Christ, Christians are encouraged to exercise discernment wisely, uphold humility, and manifest love. This is not only a response to God’s grace, but also a reflection of the kingdom that Jesus inaugurated — a kingdom marked by justice, peace, and joy in the Holy Spirit (Romans 14:17). For as Paul eloquently puts it, “The only thing that counts is faith expressing itself through love” (Galatians 5:6).
