What Is Legalism?

The word “legalism” comes from the word “legal,” connected to the idea of law. Its most distant origin is the Latin lex / legis, meaning “law.”

Christians should love God’s law. Although legalism is something negative, we should not treat God’s law itself as something bad. And here I am referring not only to the Law of the Old Testament, but also to all the commandments, principles, and directions God has given us in Scripture.

Therefore, the law is something good because it is God speaking to us. Besides showing us our sin and our inability to save ourselves, the psalmist delighted in the law because he saw in it the wisdom of God. In Psalm 119, he speaks about the law with love because it guides, corrects, protects, and leads us closer to truth. Whoever loves God naturally begins to love what comes from Him.When we look at the New Testament, we also see Paul saying that “the law is holy, and the commandment holy and righteous and good.”

But humanity, because of its sinful nature, has the tendency to turn something good into something harmful — and that is how legalism is born.The word “legalism” may sound like simply living according to the law or having a life based on rules. At first glance, that may not sound so negative. However, legalism can be defined as making obedience to the law the basis of our acceptance before God.

That “law” may begin with biblical commandments, but legalistic thinking often expands far beyond Scripture itself. Life becomes centered not only on God’s commands, but also on religious rituals, human traditions, and man-made rules — many of which are not even biblical.

Legalism happens when someone turns the Christian life into a checklist of rules, as if following certain practices is what guarantees God’s love or salvation, even while verbally affirming that salvation comes by grace.

“For sin shall not have dominion over you: for ye are not under the law, but under grace.”
— Romans 6:14

“For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: not of works, lest any man should boast.”
— Ephesians 2:8–9

“Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ.”
— Galatians 2:16

The Christian’s Relationship With the Law

First, we need to understand the Christian’s relationship with the Law in light of Scripture. At times, this relationship may even seem ambiguous because the Bible speaks about the Law in different ways depending on the context.

As we saw earlier, in some passages the Law is called holy, righteous, and good; in others, Paul says we are “not under the law.” The key is understanding which aspect of the Law each text is referring to.

The Law was given during another stage in the history of redemption, under the Old Covenant. At that time, God’s people lived under civil, ceremonial, and moral laws, along with sacrifices, priesthood, and temple worship. The Law served to separate Israel from the nations and reveal God’s holy standard. Its purpose was to be obeyed.

Today, we live under grace. God’s people are now the Church. But this does not mean the Law became evil or useless. On the contrary, the Law remains good because it comes from God. What changed was the way God’s people relate to it.

Some specific laws from the Old Covenant — especially ceremonial and civil laws tied directly to Israel — no longer apply to Christians in the same way. Yet God’s moral principles still reveal His will and character.

The Law also serves another important purpose revealed in Scripture: it exposes sin. It reveals God’s perfect standard of holiness and shows humanity’s inability to achieve righteousness through personal effort. The Law functions like a mirror — it does not cure sin, but it reveals the problem.

Because of this, the Law ultimately points people to Christ. When a person realizes they cannot perfectly fulfill God’s commands, they begin to understand their need for grace, forgiveness, and salvation. The ultimate purpose of the Law was never to imprison humanity forever in a system of rules, but to lead sinners to the Savior.

The Problem With Legalism

The problem with legalism is that the desire to obey does not flow from inner transformation, relationship with God, and the work of His grace. Instead, life with God becomes ritualistic rather than relational — a false form of religiosity.

Legalism prevents us from living a healthy Christian life and harms the body of Christ.

John Piper once said:

“Legalism is more subtle, more widespread, and ultimately more destructive than alcoholism. Satan disguises himself as an angel of light and even uses God’s commandments as a base of operation.”

And Hernandes Dias Lopes said:

“Legalism is a deadly broth that has oppressed many people in their spiritual lives.”

Characteristics of a Legalistic Person

Let us look together at some biblical characteristics of legalism. As examples, we will use the Pharisees, teachers of the law, and many of the religious leaders among the Jews.

We might call them the greatest legalists in the Bible — not because Scripture explicitly uses that word, but because their lives clearly reflected a religion centered on rules, rituals, and human traditions. Ironically, although they clung tightly to the Torah, they often neglected commandments and principles more deeply connected to God’s heart — things like mercy, love, forgiveness, and compassion.

Judgmental Spirit

The Woman Caught in Adultery

(John 8:1–11)

The Pharisees brought to Jesus a woman caught in adultery. Their goal was not restoration, but condemnation and an attempt to trap Jesus. Jesus responded:

“He that is without sin among you, let him first cast a stone at her.”One by one, they walked away.The point was not that sin does not matter, but that they acted like perfect judges while ignoring their own sins. They found it easy to expose the failures of others while refusing to examine themselves.

Traditions Above Scripture

One of the greatest conflicts between Jesus and the Pharisees involved this exact issue: they elevated human traditions above the Word of God.

Many traditions may have started with good intentions, but over time they became treated as sacred rules carrying the same authority as God Himself. Jesus confronted this because their religion had become more centered on human customs than on the truth of Scripture and genuine transformation of the heart.

“You nullify the word of God by your tradition.”
— Mark 7:13

Ritual Hand Washing

(Mark 7:1–13)

The Pharisees criticized Jesus’ disciples because they ate without performing the traditional ceremonial washing of hands. This was not about hygiene — it was a religious ritual created by Jewish tradition. Jesus answered:

“You leave the commandment of God and hold to the tradition of men.”And later:

“Making void the word of God through your tradition.” In other words, they cared more about rituals than about what God had actually commanded.

The “Corban” Tradition

Jesus gives another strong example in Mark 7:9–13.

The Law commanded people to honor and care for their parents. But there was a tradition called Corban, where someone could declare their possessions “dedicated to God” and then use that as an excuse not to help their parents.

In practice, tradition became a loophole for disobeying a clear commandment of God. Jesus showed that traditions must never cancel out what God has already spoken.

Religious Appearance Without Real Transformation

“This people honors Me with their lips, but their heart is far from Me.”
— Matthew 15:8 Their traditions maintained an appearance of spirituality, but their hearts were distant from God.

Not Every Tradition Is Wrong

Not all traditions are bad. There are good traditions, such as:

• singing hymns,

• gathering as a church,

• celebrating communion,

• organized forms of worship.

The problem begins when:

• tradition becomes treated like divine law,

• human customs are elevated above Scripture,

• people who do not follow certain customs are treated as less spiritual,

• external rules replace relationship with God.

How Does This Happen Today?

This can happen whenever people begin treating as “sin” things the Bible does not clearly condemn.

Common examples include:

• specific clothing rules,

• musical styles,

• cultural customs,

• man-made standards of holiness,

• rigid expectations about worship styles.

Placing Heavy Burdens on Others

One of the Pharisees’ greatest problems was placing heavy burdens on people, turning faith into something exhausting and oppressive.Jesus addressed this in Matthew 23, saying they “tie up heavy burdens, hard to bear, and lay them on people’s shoulders.”

Their religion was filled with rules, pressure, and outward performance, causing people to live in constant fear of failure and never feel accepted before God.

Often they created demands far beyond what God had actually commanded. Spirituality became measured by external customs and religious performance. Instead of bringing people closer to God, they placed guilt and weight upon them. Life with God became an impossible system to achieve.

Spiritual Insensitivity

In Mark 3, Jesus healed a man with a withered hand inside the synagogue. Before healing him, Jesus looked at the Pharisees with grief because of the hardness of their hearts.

They were observing Jesus not to learn or rejoice, but to accuse Him. The suffering of a man mattered less to them than preserving their religious interpretations.

Jesus also said in Matthew 15:8: “This people honors Me with their lips, but their heart is far from Me.”Outwardly, they appeared spiritual, but inwardly, they were far from God. Religion had become routine, appearance, and pride without real transformation of the heart.

Their spiritual insensitivity also caused them to judge people without compassion. They saw sinners merely as people to condemn, while Jesus saw people in need of repentance, healing, and salvation.

Christ never minimized sin, but He also never lost mercy toward sinners.

Are You Legalistic?

These are only some characteristics of a legalistic person. And even if we are not as extreme as the Pharisees, we are still susceptible to these attitudes — partly because of the legalistic culture around us, and partly because of our own sinful hearts.

Reflect prayerfully before God about your life. If you recognized yourself in any of these characteristics, seek transformation from Him.

Legalism prevents us from living a joyful and healthy Christianity. It harms our relationship with God, damages the body of Christ, and weakens our witness before unbelievers.

Legalism is more common in us than we often realize — even if only in subtle ways or in specific areas of life. That is why this is something we must continually examine, asking God to transform us so we may experience a healthy and grace-filled faith.
