“Bear one another’s burdens, and thereby fulfill the law of Christ.”

— Galatians 6:2, NASB95

Introduction

There is a phrase the Apostle Paul uses only once in all his letters, almost in passing — and yet it gathers the whole of Christian ethics into four words. Writing to the churches of Galatia, the very churches he had warned against the slavery of law-keeping, Paul says: “Bear one another’s burdens, and thereby fulfill the law of Christ” (Gal 6:2). The Greek is ho nomos tou Christou (ὁ νόμος τοῦ Χριστοῦ). It is a startling expression. Paul has spent five chapters insisting that no one is justified by works of the Law — and then, at the very end, he hands his readers a law after all. Not the Law of Moses. The Law of Christ.¹

This raises the question that this paper exists to answer. If we are saved by grace through faith, apart from works of the Law, in what sense does the believer live under any law at all? And if there is a law that still governs the Christian — a nomos, a binding rule of life — what is it, where does it come from, and how is it kept without collapsing the gospel back into the very legalism Paul died fighting?

Our answer, stated plainly, is this. The Law of Christ is not a new code of regulations swapped in for an old one. It is the cruciform love of Jesus Christ — commanded by Him, defined at His cross, and reproduced in His people by the Holy Spirit. It is the moral substance of everything God ever required, taken up into a Person, intensified by His example, and written on the heart by His Spirit. In a single sentence, the Law of Christ is love with a cross in the middle and a neighbor in front of it.

Three convictions hold this paper together, and they correspond to three questions every honest believer eventually asks. First, how does this law relate to the Law of Moses? — our answer: love fulfills and surpasses it. Second, where does the power to keep it come from? — our answer: it is received before it is rendered. Third, is this not just legalism in a softer key? — our answer: no, for the Law of Christ is the gift of grace, not the achievement of effort. We will take each in turn, letting the New Testament’s own vocabulary lead the way.

The Vocabulary of a New Law

“Law” in a Letter About Freedom

The word nomos (νόμος) is among the most flexible and most freighted in Paul’s vocabulary. It can name the Mosaic legislation given at Sinai; it can name the Pentateuch, or the whole Old Testament; it can name a governing principle, an operative rule, even a recognizable pattern — as when Paul speaks of “the law of sin” at work in his members (Rom 7:23). When Paul writes of “the law of Christ,” he is plainly not pointing his readers back to Sinai. He is naming a binding rule of life that belongs to Christ and bears Christ’s shape. The paradox is intentional. In a letter whose battle cry is freedom, Paul insists that freedom has a form, and that form has a name.

The Law of Christ (Galatians 6:2)

The setting of the phrase matters enormously. Paul does not define the law of Christ in the abstract; he defines it by an action. “Bear one another’s burdens, and thereby fulfill the law of Christ.” The verb rendered “bear” is bastazō (βαστάζω) — to pick up and carry, to take the weight of something onto yourself. The law of Christ, then, is first shown to us not as a list but as a posture: the strong stooping under the load of the weak, the whole community carrying what no single member can carry alone. The genitive “of Christ” is doing real work. This law belongs to Christ, derives from Christ, and is patterned after Christ — the One who bore our burdens in His own body to the tree (1 Pet 2:24). To fulfill His law is to do, in miniature and toward one another, what He did for us at Calvary.

Under Christ’s Law (1 Corinthians 9:21)

The only other place the expression surfaces is in 1 Corinthians, where Paul describes how he becomes all things to all people. To those without the Law he became as one without the Law — and then he adds a crucial qualification: “though not being without the law of God but under the law of Christ” (1 Cor 9:21). The phrase here is ennomos Christou (ἔννομος Χριστοῦ) — literally, “in-lawed to Christ,” held within Christ’s law. Paul will not let anyone mistake his freedom for lawlessness. He is not an antinomian who has escaped all obligation; he is a man who has exchanged one Lord’s law for Another’s. The Christian is never simply “without law.” The Christian is bound — bound to Christ, and through Christ to the neighbor.

Royal Law, Law of Liberty, Law of the Spirit

Paul is not alone in reaching for legal language to describe the new covenant life. James calls the command to love your neighbor the nomos basilikos (νόμος βασιλικός), the “royal law” — the law of the King, the sovereign command of the kingdom (Jas 2:8). The same letter twice names it the “law of liberty,” nomos eleutherias (Jas 1:25; 2:12), a law whose keeping does not enslave but frees. And Paul, in the soaring eighth chapter of Romans, speaks of “the law of the Spirit of life in Christ Jesus” that has set us free from the law of sin and death (Rom 8:2). Royal law, law of liberty, law of the Spirit, law of Christ — a cluster of expressions, each lighting up the same reality from a different angle. There is a rule that governs the redeemed. It is the rule of love, given by the King, enacted in freedom, and powered by the Spirit.

The Law of Christ and the Law of Moses

Continuity: The Law Was Always About Love

We must begin by refusing a false start. The Law of Christ is not love invented out of nothing, as though the God of Sinai were a stranger to the God of Calvary. The command to love was already the heart of the old Law. “You shall love the Lord your God with all your heart and with all your soul and with all your might” — the Shema of Deuteronomy 6:5. “You shall love your neighbor as yourself” — the command embedded in Leviticus 19:18, long before any disciple heard it from Jesus’ lips. When a scribe asked Jesus which commandment was greatest, He did not improvise; He quoted Moses. And then He said something the rabbis had long sensed but rarely stated so flatly: “On these two commandments depend the whole Law and the Prophets” (Matt 22:40). The Law had always hung on love. Christ did not introduce love to the Law. He revealed that love had been the point of the Law all along.

Fulfillment, Not Abolition

This is why Jesus could say, with no contradiction, “Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill” (Matt 5:17). The verb is plērōsai (πληρῶσαι) — to fill full, to bring to its intended completion. Christ is not the eraser of the Law but its destination. He keeps it perfectly, He carries its penalty fully, and He brings its deepest intention — a people who love God and neighbor from the heart — to realization in Himself and, by His Spirit, in His people. The Mosaic Law pointed beyond itself to a righteousness it could command but never create. In Christ, that righteousness arrives. The arrow finds its mark.

Discontinuity: A Commandment New in Kind

And yet the New Testament insists that something genuinely new has happened. On the night before His death, Jesus said, “A new commandment I give to you, that you love one another, even as I have loved you” (John 13:34). Greek has two words for “new.” Neos (νέος) means new in time, recently arrived. Kainos (καινός) means new in kind, qualitatively unprecedented — the same word used for the “new creation” and the “new covenant.” Jesus chose kainos. The novelty is not the bare command to love one’s neighbor; that was old. The novelty is the standard: kathōs ēgapēsa hymas, “as I have loved you.” The old Law set the measure of love at the self — love your neighbor as yourself. The Law of Christ sets the measure at the Savior — love one another as I have loved you. Love is no longer calibrated to our self-interest but to His self-giving. That is what makes the commandment new in kind. Its ceiling has become a cross.

Three Traditions in Conversation

Faithful Christians have framed the relationship between these two laws in different ways, and honesty requires that we name them charitably before stating our own. The Reformed and covenantal tradition tends to distinguish the moral, civil, and ceremonial dimensions of the Mosaic Law, regarding the moral law — summarized in the Decalogue — as perpetually binding, and the law of Christ as that same moral law now placed in the believer’s hand by grace. This is the tradition’s celebrated “third use of the law,” the law as a guide for the justified, which Calvin called its principal use for believers. The Lutheran tradition presses the law’s work of exposing sin and driving us to Christ, while still affirming, in the Formula of Concord, a guiding use for the regenerate. New Covenant Theology argues that the Mosaic covenant functioned as a unified whole that has reached its terminus in Christ, so that the believer’s direct rule is not the Sinai code but the law of Christ — a body of instruction grounded in Jesus’ teaching, His example, and the apostolic word, overlapping the old commandments in content while no longer binding through them. Dispensational theology likewise distinguishes the present age of grace from the Mosaic economy, locating the believer under the law of Christ rather than the Law of Moses.

Our Position

We hold that each of these traditions has seen something true, and that they converge more than they divide. With covenant theology, we affirm that God’s moral character does not change and that the ethical substance of the old Law abides. With New Covenant and dispensational readings, we affirm that the Mosaic covenant as an administration has reached its goal in Christ, so that the believer’s immediate rule of life is the law of Christ — not Sinai mediated by Moses, but the moral heart of the Law taken up into Jesus, intensified by His pattern, and re-centered on His person. The Law of Christ thus stands in both continuity and discontinuity with Moses: continuous in substance, for it is still love of God and neighbor; discontinuous in form, for its standard is now the crucified Lord and its power is now the indwelling Spirit. We hold this without rancor toward brothers and sisters who order it differently, because on the deepest point we are agreed. Whatever else the law of God requires, it requires love — and that love has been made flesh.

The Law of Christ is love with a cross in the middle and a neighbor in front of it.

The Content of the Law of Christ: Cruciform Love

Love Defined by the Cross

If love is the content of the Law of Christ, then everything depends on what we mean by the word. Here the New Testament refuses sentimentality. It does not let us pour our own meaning into agapē (ἀγάπη) and call it Christian. It points us to a hill outside Jerusalem and says: that is love. “By this we know love, that He laid down His life for us” (1 John 3:16). “In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins” (1 John 4:10). John does not abstract love away from wrath and sacrifice; he locates love precisely there, at the place where mercy and justice meet. The cross is the dictionary entry for the word love in the Christian vocabulary. To speak of the Law of Christ is therefore never to speak of mere niceness, affirmation, or warm feeling. It is to speak of a love with a cost, a love that bleeds, a love shaped like a cross.

The Standard: “As I Have Loved You”

This is why the standard of the new commandment is so bracing. “Love one another, as I have loved you.” The verb ēgapēsa is aorist — a completed, accomplished act. Jesus is not pointing to some hypothetical future affection but back across His whole ministry of washed feet and welcomed sinners, and forward to the cross then only hours away. That love is the measure. Which means the Law of Christ can never be satisfied by what comes naturally to us. The standard is not our temperament, our capacity, our emotional bandwidth, or our family of origin. The standard is Christ Himself. This is at once the most impossible demand ever laid on the human heart and the most freeing, because the One who sets the standard is the same One who, by His Spirit, supplies it.

How Love Fulfills the Whole Law

Paul draws the threads together with a claim that would be reckless if it were not apostolic: love fulfills the entire Law. “He who loves his neighbor has fulfilled the law” (Rom 13:8). The verb is peplērōken (πεπλήρωκεν), perfect tense — has fulfilled and stands in the state of having fulfilled. He continues: the commandments against adultery, murder, theft, and coveting “are summed up in this saying, ‘You shall love your neighbor as yourself’ … therefore love is the fulfillment of the law” (Rom 13:9–10). To the Galatians he says it even more compactly: “The whole Law is fulfilled in one word, in the statement, ‘You shall love your neighbor as yourself’” (Gal 5:14) — en heni logō, in a single utterance. The rabbis counted six hundred and thirteen commandments and debated which were weightier. Paul says every one of them is gathered up in the act of love. Love does no murder, for love does no harm. Love does not steal, for love does not take. Love does not betray, covet, or deceive, for love wills the good of the other as surely as it wills its own. Where love is present, the Law is not abolished; it is honored down to its root.

The Engine of the Law of Christ: Grace, Not Legalism

The Law God Writes on the Heart

Here we arrive at the difference between the Law of Christ and every form of religious moralism. The old covenant inscribed its commands on tablets of stone, outside the person, demanding a righteousness it could not produce. The new covenant promises something Sinai never could. “I will put My law within them and on their heart I will write it” (Jer 31:33). Paul says the Corinthian believers themselves are this fulfilled promise — a letter of Christ, “written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts” (2 Cor 3:3). The Law of Christ is not first an external requirement but an internal reality. Thomas Aquinas saw this with great clarity: the New Law, he argued, is principally the grace of the Holy Spirit given to those who believe in Christ, and only secondarily a matter of written precepts. The commandment is real, but the commandment is not the engine. The Spirit is the engine. The law of Christ comes to us not as a demand pressing from without but as a life welling up from within.

Received Before It Is Rendered

This is why the Christian life, rightly understood, begins not with effort but with reception. “We love, because He first loved us” (1 John 4:19). “The love of God has been poured out within our hearts through the Holy Spirit who was given to us” (Rom 5:5). The same Spirit who pours God’s love into us is the Spirit who then bears its fruit through us — “the fruit of the Spirit is love” (Gal 5:22). Notice the order Scripture refuses to negotiate. Love is response before it is initiative; reception before mission; being loved before loving. The believer who tries to keep the Law of Christ by sheer resolve will end exhausted, pouring from a cup never filled. The believer who learns to sit and receive — to remember each morning that he is beloved before he has done anything — discovers that obedience flows downhill from a full reservoir. Striving manufactures a thin and brittle love. Abiding receives an inexhaustible one.

Freedom From Performance

It follows that the Law of Christ is the very opposite of performance religion. “It was for freedom that Christ set us free” (Gal 5:1). The gospel does not invite us onto a treadmill where our acceptance hangs on our output. Our acceptance is settled, finished, secured in Christ’s finished work — and from that acceptance, never for it, obedience is born. Martin Luther captured the paradox in a single famous breath: a Christian is a perfectly free lord of all, subject to none; and a Christian is a perfectly dutiful servant of all, subject to all. Free, because nothing we do can add to or subtract from the love that holds us. Dutiful, because that love, having seized us, cannot stay still. The gospel does not merely ignite the Christian life and then leave us to keep it burning by willpower; the gospel is the fuel that keeps the fire alive every day. We do not love in order to be accepted. We love because we already are.

Neither Legalism Nor License

Two ditches line this road, and the Law of Christ steers between them. On one side is legalism, which makes love into a ladder and the gospel into a wage. On the other side is license, which hears the word freedom and concludes that nothing is required at all. Paul slams that door in the same breath he opens it: “You were called to freedom, brethren; only do not turn your freedom into an opportunity for the flesh, but through love serve one another” (Gal 5:13). Christian freedom is not freedom from the neighbor but freedom for the neighbor. Augustine’s famous counsel — “Love, and do what you will” — is endlessly misquoted as if it licensed anything the heart desires. Augustine meant the reverse: let love be the root, and whatever grows from that root will be good, because love wills no evil to the one it loves. Rightly understood, this is not the abolition of obedience but its perfection. The one who truly loves needs no list of prohibitions, because love has already fulfilled them all.

Love begins with being loved — because the Law of Christ always starts with Christ.

The Shape of Obedience: Bearing Burdens Together

We return, at the last, to where Paul first set the phrase — not to a private spirituality but to a community carrying its own weak. “Bear one another’s burdens, and thereby fulfill the law of Christ.” The Law of Christ is irreducibly plural. It is kept in the company of others or it is not kept at all. This is why the New Testament is saturated with the little reciprocal word allēlous (ἀλλήλους), “one another,” appearing more than one hundred times: love one another, bear with one another, forgive one another, encourage one another, confess to one another, welcome one another, honor one another, wash one another’s feet. The law of Christ has no abstract object. It always lands on a face — the difficult brother, the wounded sister, the new believer, the aging saint, the neighbor God has providentially placed within reach.

This is also the Church’s great apologetic. “By this all men will know that you are My disciples, if you have love for one another” (John 13:35). Jesus did not name eloquence, strategy, or argument as the proof of His reality in the world. He named love among His people. When the watching world sees a community that bears burdens it has no obligation to carry, that forgives debts it has every right to collect, that welcomes the unimpressive and honors the overlooked, it is seeing the invisible God made visible. The keeping of the Law of Christ is evangelism by demonstration. The love we practice within the body is the love that spills, finally, into the world — toward the wounded one sitting alone on some park bench, who has not yet been told that there is a place where people like us start over.

Applying the Law of Christ to Daily Life

A doctrine of love that never reaches a checkout line is no Christian doctrine at all. The Law of Christ is not learned in seminars; it is formed in the ordinary places where our schedule collides with someone else’s suffering. Four practices follow directly from everything above.

Begin by Being Loved

Find your chair. Build, in your week, a place and a moment where you sit until your heart remembers that you are beloved — before you have done anything, before you have succeeded at anything, before you have loved anyone. The love you extend tomorrow will not come from your willpower; it will come from the well you lower into today. If the well is empty, the bucket comes up dry. Receptivity comes before activity. This is not laziness; it is the foundation of every strong love that will ever pour out of you.

Let the Standard Be Christ, Not Your Capacity

Stop measuring your obligation by what comes naturally. The standard of the Law of Christ is not your temperament but His self-giving. This will expose you — the part of love’s anatomy that comes hardest, the trait that rises in resistance when you read it: patience, or keeping no record of wrongs, or refusing to seek your own. That exposed place is precisely where the Spirit is forming Christ in you. You will not perfect it. But the Spirit who indwells you is bringing it slowly to completion, and the difficult conversation, the late-night text, the family dinner are not interruptions of your discipleship. They are the curriculum.

Find the Neighbor in Front of You

The Law of Christ never floats in the air; it always lands on a name. So ask, honestly: whose face comes to mind? A coworker, a wayward child, an aging parent, a former friend, a fellow believer who has become difficult, a spouse whose love has felt one-sided. That is not a coincidence; that is the Spirit naming the person Christ is calling you to love this week. Then ask the diagnostic question of embodied love: what does love require of me in this relationship? Sometimes the answer is to cover an offense rather than expose it. Sometimes it is to put up with a weakness rather than fix it. Sometimes it is to bind a fracture with your own faithfulness. The form changes; the verb does not. Love acts.

Keep It in Community

Do not attempt the Law of Christ alone. It is a “one another” law by design. Reach out to the brother or sister you have drifted from. Honor someone publicly. Pray for someone by name. Confess something small to a believer who has earned the right to hear it. Take the meal, make the visit, send the card. These ordinary practices are not extraordinary heroics; they are the daily ligaments by which the Spirit holds the body of Christ together and grows it into maturity. And as we practice them inside the gathered community, the Spirit forms in us the muscle to carry them outward — toward the one on the bench who does not yet know he is within reach of grace.

Love moves toward the wounded because that’s what Christ did for us.

◆ ◆ ◆

Conclusion: Love With a Cross in the Middle

We set out to answer how a people saved by grace, apart from the works of the Law, can still be said to live under a law — the law of Christ. The answer has turned out to be the gospel itself, viewed from the angle of obedience. The Law of Christ is not Sinai returned in disguise, nor is it a vague benevolence cut loose from command. It is the love of God, defined at the cross, commanded by the Lord who first lived it, written on the heart by the Spirit, and worked out among a people who bear one another’s burdens. It fulfills the old Law by reaching the love the Law was always aiming at. It surpasses the old Law by raising the standard from the self to the Savior. And it does what no law of stone could ever do, because it is carried not by our resolve but by the indwelling Christ.

So the believer is, in the end, both perfectly free and perfectly bound — free from the curse, the condemnation, and the treadmill of the Law; bound, by a love stronger than any statute, to the Christ who loved him and to the neighbor Christ has placed in front of him. Faith works through love (Gal 5:6). The tree of grace bears the fruit of obedience. And the harvest is nothing less than the character of Christ formed in His people and made visible to a watching world.

May this be more than a paper to be read and filed. May the Spirit who poured the love of God into our hearts bring that love to completion in us — until His love, formed in us, becomes the love we have to give. To Him who is able to do far more abundantly beyond all that we ask or think, be the glory in the church and in Christ Jesus to all generations forever and ever. Amen.

The Law of Christ is love with a cross in the middle and a neighbor in front of it.

Notes

¹ The exact phrase “the law of Christ” (ho nomos tou Christou) occurs only here, in Galatians 6:2. Paul names the same reality a second time in 1 Corinthians 9:21, but with a different construction: there he calls himself ennomos Christou — “in-lawed,” or “under the law,” to Christ — an adjective rather than the full noun phrase. The difference is instructive rather than troubling. Galatians gives the law’s content (bear one another’s burdens); 1 Corinthians gives Paul’s status under it (never lawless, always bound to Christ). That he reaches for the same reality from two angles, rather than repeating a fixed formula, suggests a settled conviction and not merely a coined phrase. Same Lord, same law, two faces.
