The line between truth and opinion is not thin. It is not negotiable. Truth is what God has spoken and commanded. Opinion is what he has left open, entrusting his people to judge with wisdom. Our judgmental restraint obedience and humility. It is not weakness. The distinction between what God said and how I feel matters because the church is always tempted to collapse it. Some raise human judgment to the level of divine command. Others treat God’s clear word as if it were optional. Both errors wound the body. Both displace the authority of God with the voice of man.

Truth is never fluid. It is not shaped by preference or consensus. It is what God has made known. Christ himself says, “I am the truth” (Jn 14:6). He prays, “Your word is truth” (Jn 17:17). For us to reject truth is really to reject both God and his revealed will. Paul commands Timothy to “rightly handle the word of truth” (2 Tim 2:15). Truth stands because God has spoken.

Opinion belongs to another sphere. Opinions lives where God has chosen not to legislate. These opinions or “adiaphora” are “issues that the Bible neither commands nor forbids….If God does not address these things, they are in the arena of the “freedom of the Christian” (1 Corinthians 9). If God has left an issue open, we are not to compel other people to act in a certain way. We are not authorized to “fill in the gaps” of Scripture with our own laws and regulations. We are never to speak our own word while pretending that it is the word of God himself.” (Mueller, Called to Believe, Teach, and Confess: An Introduction to Doctrinal Theology, 72).

Matters of opinion can be wise or unwise.Here the Christians may reason, persuade, and exhort. But in the realm of opinions, the Christian does not command or draw lines of fellowship or become suspicious of another’s faithfulness. He does not speak as Lord where the Lord has not spoken or pretend to be the judge when the Judge has not spoken. We must have the fortitude to stand and humility to welcome. If we bind where Christ has left free, we becomes tyrannical. If she loosens what Christ has bound, she becomes faithless.

The Center Must Hold.

Scripture names certain truths as necessary. They are not optional because they belong to the gospel itself. Christ, as the Son of God, shares in divine identity (Jn 5:26). We must believe in the resurrection on the third day as Paul writes, “I delivered to you as of first importance…that Christ died for our sins…that he was buried, that he was raised on the third day” (1 Cor 15:3–4). Christ commands baptism (Matt 28:19) and the Supper (Luke 22:19; 1 Cor 11:24–25). These are not human traditions. They are given acts in which the church receives and proclaims the benefits of Christ. The apostolic church itself distinguished what was “necessary” and what was not (Acts 15:28). That judgment preserved both truth and mission.

To alter the faith once and for all delivered to the saints (Jd 3) is no small thing. Altering the faith is another gospel (Gal 1:6–9) and we can do this by being too liberal or too conservative.

Outside this center lies a wide field. The tradition has called it adiaphora. Things neither commanded nor forbidden. Paul treats this field in Romans 14. One esteems a day. Another does not. His instruction is not to flatten the difference, but to govern it: “Each one should be fully convinced in his own mind” (Rom 14:5). Yet conviction alone is not enough. Love must rule it. “If your brother is grieved…you are no longer walking in love” (Rom 14:15). The same logic governs 1 Corinthians 8–10. The strong are right. An idol is nothing (1 Cor 8:4). Yet knowledge, when detached from love, destroys. “By your knowledge this weak person is destroyed, the brother for whom Christ died” (1 Cor 8:11). So Paul limits his own freedom. Not because the act is sinful, but because love refuses to wound. Freedom exists, but it is not absolute. Freedom bends toward the good of the other.

Here the question shifts. Not, “What may I do?” but, “What builds up?” When the church mistakes adiaphora for necessity, she creates new laws. This easily becomes a yoke of slavery (Gal 5:1). When she treats necessity as adiaphora, she dissolves the faith itself. Both moves—overcorrecting toward the left or right—tear at the same fabric of truth and attempt to remove the sovereign God from his throne.

Recognizing this distinction guards the church on two sides. It protects her from legalism. “Why…do you submit to regulations?” Paul asks (Col 2:20–23). Human rules cannot produce holiness. They only burden the conscience. Christ has already spoken where obedience is required. Recognizing this difference also guards the church from license. Freedom is not aimless. It is tethered to truth. The necessary articles anchor the church so that her liberty does not drift into confusion.

Unity.

Paul urges the church to be “eager to maintain the unity of the Spirit in the bond of peace” (Eph 4:3). That unity is not built on sameness in all things. It rests on shared confession of the Lord and submission to his word and work (Eph 4:5). When that center is held, the church can bear real adiaphora differences without fracture. But when the line collapses, division follows. When opinion is preached as law, consciences are crushed. When truth is reduced to preference, the gospel itself is emptied. The apostolic pattern remains clear. Contend for the faith (Jude 3). Pursue what makes for peace (Rom 14:19).A healthy church is and healthy Christians are firm at the center and flexible at the edges.

At the center stand those things God has revealed plainly and bound upon the conscience. Here the church does not hesitate. She does not soften her voice or adjust her terms. She confesses what has been given. Jesus is the Son of God. The Spirit shares in the divine identity. There is One Lord. One faith. One baptism. Christ crucified for sinners, raised for our justification and things like these. These are not conclusions we reached. They are truths we received. The church does not steward them by improving them, but by guarding and proclaiming them. To waver here is not humility. It is loss and it is rebellion.

Yet the same church, if she is to remain faithful, must learn restraint. There are matters the Lord has not fixed with command. Here Scripture gives principles, patterns, and examples, but not a binding rule in every case. And so the church must judge. Carefully. Patiently. With a conscience tethered to the Word, yet not pretending the Word has said more than it has. This kind of judgment requires maturity. It cannot be reduced to instinct or preference. This too is rebellion against God. It is, sadly, manifested in supposed rebellion against me or popular leaders. It asks: What serves the gospel? What builds up the body? What honors Christ in this place, among these people?

This is where many fail. Some fear disorder so much that they fill every silence in Scripture with law. They tighten what God has left open. The result is a church burdened with prominent loud personalities where conscience is no longer ruled by God’s voice but by accumulated expectations and demands of “Diotrephes.” Others fear constraint so much that they loosen what God has made firm. They speak of freedom, but what they practice is drift and ideologies so strict they recoil at any conservative or traditional views. The center erodes, and with it the substance of the faith.

The apostolic pattern cuts through both errors. Where God has spoken, the church speaks with him. Not above him, not beside him, but after him. She echoes his Word with clarity and with confidence. Where he has not spoken, she does not rush to fill the gap with certainty she does not possess. She reasons. She counsels. She persuades. And she does so under the rule of love.

Love is not an alternative to truth. Remember, the same God is described as both “love” and “truth.” It is the right expression of truth among a people who share one Lord. In matters that are open, love limits freedom without denying it. It refuses to turn liberty into a weapon. It bears with the weak, not as a concession, but as an obligation grounded in the cross. The brother is not an obstacle to my freedom. He is one “for whom Christ died” (1 Cor 8:11). That fact reorders everything.

In the Final Analysis

We, the church, must learn a kind of moral texture. The church is designed by God and filled with humans. The church knows the difference between what must be believed and what may be practiced differently. She can endure disagreement without dissolving into division, because her unity does not depend on uniformity in all things, but on shared submission to Christ.

In such a church, truth stands. It is not negotiated or diluted. Rather truth stands because it is respected. We refuse to add to or take away from what God has said. Truth stands because God has spoken, and his Word does not bend to the present age or idealize a past age. In this way, the gospel is not entangled in unnecessary demands, nor stripped of its necessary claims. It moves with clarity and power, because nothing essential has been surrendered, and nothing unnecessary has been imposed.

This balance is not natural. It must be learned, and learned again. It requires us to know the difference between authority and overreach. But where that balance is kept, the church becomes recognizable again. Not anxious, not brittle, not adrift. Steady. Clear. Alive under the Word of the living God.
