The Two Dangers: Legalism and License

The Two Dangers Legalism and license look like opposites. They’re the same mistake going in different directions.

Scripture: Galatians 5:1, 13–14; Romans 6:1–2, 15; 1 Peter 2:16; James 1:25; Matthew 22:36–40

There’s a pattern a lot of people have lived through without having a name for it.

You grow up in a Christian environment where everything is moralized. Every choice is loaded. What you wear, what you watch, what you listen to, whom you spend time with, how you spend your money, what you do on a Sunday afternoon — each of it gets treated as if your faithfulness depended on it. The boundary between actual biblical commands and the surrounding culture’s preferences gets fuzzy. After a while, everything starts to feel like sin or might-be-sin.

You leave that, eventually. Maybe you walked out one day after a sermon that finally broke you. Maybe you slowly stopped showing up. Maybe you stayed but quietly stopped believing the framework. However it happened, you got out from under a system that was treating everything as right or wrong.

And then the freedom feels like oxygen. You can do the things that were forbidden. You can not do the things that were required. You can wear what you want, drink what you want, listen to what you want, and the lightning doesn’t strike. After years of carrying weight that wasn’t yours to carry, the weightlessness is its own kind of grace.

But weightlessness has its own problems. After a while, the freedom that felt like oxygen starts to feel like fog. If everything was treated as sin under the old system, and the old system was wrong, then maybe nothing is sin. If your conscience was trained to respond to fake moral signals, then maybe conscience itself is unreliable. If the people who told you everything mattered turned out to be wrong, then maybe nothing matters.

You’ve swung from one error to its opposite, and you’ve swung so hard you’ve passed through the territory where you actually wanted to land. The legalism was wrong. But the answer to legalism isn’t to throw out moral seriousness. It’s to find moral seriousness that’s actually attached to the gospel.

What legalism is and what it misses

Legalism is the move that turns Christian life into rule-keeping.

Sometimes the rules come from Scripture, sometimes from tradition, sometimes from culture, sometimes from the personal preferences of whoever is in charge. Legalism doesn’t make a clean distinction. What matters is that the rules exist and you keep them. Compliance is the measure of faithfulness. The Christian life becomes a long performance review.

The damage is real. Legalism produces people who are exhausted from trying to keep up. People who become very good at outward compliance while their interior lives go untended. People who weaponize the rules against others as a way of feeling secure in their own keeping of them. People who confuse their tradition’s preferences with God’s commands and then are devastated when they realize the difference. Most painfully, people for whom the gospel itself becomes hard to hear, because they’ve been formed to believe their standing with God depends on what they do rather than what Christ has done.

What legalism misses is the gospel itself. The whole New Testament insists that we aren’t justified by keeping rules — that we’re accepted by God on the basis of Christ’s work, not ours. Legalism keeps trying to add a contribution where Scripture says no contribution is needed. It treats the gospel as a starting point and then adds rules on top — rules that, in practice, become what actually determines whether people are accepted.

Legalism asks the wrong question. It asks “what am I allowed to do?” and treats the answer as if it were the whole of the Christian life.

What license is and what it misses

License is the move that, having recognized legalism was wrong, concludes that moral seriousness itself was the problem.

This is the swing I described in the opening. The person who has been hurt by legalism leaves it — rightly. But in leaving the over-restrictive system, they sometimes leave behind the entire framework of moral seriousness that the system was distorting. The reasoning goes: if my old church was wrong about everything being sin, then maybe nothing is sin. If they were wrong about the rules, then maybe rules themselves are the problem.

Paul anticipates this exact move in Romans 6. He’s just spent five chapters making the case that we’re justified by grace, not by works of the law. And he asks the obvious follow-up: “What shall we say then? Are we to continue in sin that grace may abound?” His answer is immediate: “By no means! How can we who died to sin still live in it?” (Romans 6:1–2).

That same logic shows up in 1 Peter: “Live as people who are free, not using your freedom as a cover-up for evil, but living as servants of God” (1 Peter 2:16). The freedom is real. But it isn’t permission to ignore the question of how to live.

License misses what legalism also missed, but in the opposite direction. Where legalism added rules where Scripture didn’t, license erased moral seriousness where Scripture does. Where legalism couldn’t tell the difference between human preferences and divine commands, license couldn’t tell the difference between freedom from unnecessary rules and freedom from any moral framework at all.

License asks the wrong question too. It just answers it expansively instead of restrictively. Both errors treat the Christian life as a question of what’s permitted. Both miss what the Christian life is actually about.

The reverse swing

Most of what’s just been described is the swing from legalism to license. It’s the more common pattern in American deconstruction, and many readers have lived through it.

But the swing also happens in the other direction.

Someone grows up in an environment with no real moral compass. The freedom feels like everything for a while. Then it stops working. The choices that seemed liberating start to feel hollow. The lack of structure starts to feel like drift. They begin to want something that holds.

So they swing — into a system with clear answers, even if that system overreaches into territory it shouldn’t claim. The structure feels like ground at first. After years of having no framework, the framework is its own kind of grace.

But over time, the framework becomes a cage. The system claims authority over questions Scripture doesn’t address. The person who came to it looking for ground finds themselves enforcing rules they’re not sure they believe in, because the alternative is the unmoored freedom they were trying to escape.

That swing produces the same kind of injury, just at a different stage of life. And the answer to it is the same. The cure for unmoored freedom isn’t a new set of overreaching rules. The cure for both errors is what neither swing has yet found.

The root of both

Here’s why legalism and license are variations of a single problem.

Both treat the Christian life as fundamentally a question about what’s permitted. Legalism gives a restrictive answer; license gives an expansive one. But the question is the same. Both are asking what the rules are. Legalism makes them many. License makes them few or none. Neither imagines a Christian life organized around something other than rules.

The New Testament organizes the Christian life around something else entirely.

Jesus is asked, in Matthew 22, what the greatest commandment is. He gives an answer that doesn’t sit comfortably with either legalism or license. He doesn’t expand the rules. He doesn’t dissolve them. He reduces the whole of the law and the prophets to two: love God with everything you have, love your neighbor as yourself. “On these two commandments depend all the Law and the Prophets” (Matthew 22:40).

That answer is much more demanding than legalism, because it can’t be satisfied by external compliance. You can keep all the rules and not love. And it’s much more substantive than license, because it has actual content. Love isn’t a placeholder for “whatever you feel like.” It’s the active, sustained orientation of your life toward God and the people around you.

Paul makes the same move in Galatians 5. Right after his fierce defense of Christian freedom (“for freedom Christ has set us free”), he turns: “For you were called to freedom, brothers. Only do not use your freedom as an opportunity for the flesh, but through love serve one another. For the whole law is fulfilled in one word: ‘You shall love your neighbor as yourself'” (Galatians 5:13–14).

That sentence does what neither legalism nor license can do. It defends freedom and asks it to mean something at the same time. It refuses both the restrictive instinct and the unmoored one. You were called to freedom. Don’t waste it on the flesh. Use it through love.

What gets recovered

When you stop swinging between legalism and license — when you let the gospel be the actual orientation of the Christian life rather than the entry ticket to a system of rules or to no rules at all — several things become possible that weren’t possible before.

The moral seriousness comes back. Not as anxiety, not as performance, not as rule-keeping. As the genuine question of how to live a life worthy of what you’ve been given. That question has real content. It changes how you treat people, how you spend money, how you use your time, what you give yourself to. None of that is legalism. All of it is love working through Christian freedom.

The freedom comes back too. Not as license to ignore moral substance, but as actual freedom — from rules that were never God’s, from systems that overreached, from the anxious need to satisfy a standard the gospel says was already satisfied for you. The freedom is real and worth keeping.

And the swing stops. You stop swinging between two errors that are really the same error in different costumes. You start living the Christian life the way the New Testament actually frames it — grace received, love responding, freedom used in service of the people God has placed around you.

What it looks like to be done with the swing

The end of the swing isn’t a settled position somewhere between the two poles. It isn’t moderation. It isn’t a careful compromise where you keep some of the rules and drop others.

It’s a different orientation entirely.

It’s recognizing that the question wasn’t “what am I allowed to do?” in the first place. It’s recognizing that the Christian life isn’t organized around permission and prohibition but around grace and love. It’s letting the gospel actually do its work — not as a starting point you then complicate with rules, and not as a starting point you then dissolve into anything-goes. As the actual ground you stand on for the whole of the moral life.

If you’ve been swinging, you can stop. The swing itself was a response to a problem the gospel actually solves. The legalism that produced your reaction wasn’t the real Christian life. The license that felt like the cure isn’t either. The actual Christian life is something better than either, and it’s available to you.

You weren’t supposed to live in either system. You were called to freedom. You were called to love.

That’s the whole of it. Everything else is commentary.
