10 Commandments Catholic: Understanding the Decalogue in Catholic Tradition

The Catholic Church places the Ten Commandments at the heart of its moral teaching and follows a numbering tradition associated with St. Augustine. All Christians honor the same divine law, but the Catholic listing combines the commands against false worship and idols into the First Commandment and splits the command against coveting into two. This article walks through each commandment with Scripture and explanation, so you can see how Catholics understand and live out these timeless words.

The Catholic Ten Commandments: Numbering and Scriptural Foundation

If you open a Catholic catechism or study guide, the list of the Ten Commandments may look different from what you learned in Sunday school. That difference comes from two historic numbering traditions in the early Church: one associated with St. Augustine, used by Catholic and Lutheran churches, and another linked to Origen and the Eastern fathers, used by most Protestant and Orthodox churches. Both traditions use the same biblical text from Exodus 20 and Deuteronomy 5; they simply group the verses into ten commands differently.

In the Catholic numbering:

The First Commandment combines the worship of God alone and the prohibition of graven images (Exodus 20:2-6).
The Second Commandment forbids misuse of God’s name (verse 7).
The Third Commandment calls for keeping the Sabbath holy (verses 8-11).
The Fourth through Eighth Commandments deal with honoring parents, murder, adultery, stealing, and false witness (verses 12-16).
The Ninth and Tenth Commandments split the coveting prohibition into two — one about a neighbor’s wife and one about a neighbor’s goods (verse 17).

The Catechism of the Catholic Church says the Decalogue “belongs to God’s revelation” and “summarizes and proclaims God’s law” (CCC 2056-2057). We can begin with the main biblical passage:

God spoke all these words, saying, “I am Yahweh your God, who brought you out of the land of Egypt, out of the house of bondage.
— Exodus 20:1-2

The Ten Commandments Explained: A Catholic Walk Through Each Command

Below is the Catholic listing of the Ten Commandments, with the scriptural text and a brief explanation of how Catholic tradition understands each command.

First Commandment: I am the Lord your God — you shall have no other gods before me

“You shall have no other gods before me. “You shall not make for yourselves an idol, nor any image of anything that is in the heavens above, or that is in the earth beneath, or that is in the water under the earth: you shall not bow yourself down to them, nor serve them, for I, Yahweh your God, am a jealous God, visiting the iniquity of the fathers on the children, on the third and on the fourth generation of those who hate me,

— Exodus 20:3-5

This commandment calls us to worship God alone, trust him completely, and turn away from anything that tries to take his place — false gods, superstition, or modern idols like wealth, power, and pleasure. In Catholic teaching, the prohibition of graven images is not a ban on all religious art. It is a ban on worshiping created things. Catholics point to God’s command to fashion the cherubim on the ark (Exodus 25:18-22) as evidence that sacred images can help lead hearts toward God.

Second Commandment: You shall not take the name of the Lord your God in vain

“You shall not misuse the name of Yahweh your God, for Yahweh will not hold him guiltless who misuses his name.
— Exodus 20:7

Catholic teaching applies this to our speech: avoiding blasphemy, cursing, perjury, and careless use of God’s name. It also includes promises or oaths that dishonor God, along with any irreverence toward holy things. The Catechism encourages deep respect for the name of Jesus and the titles of Mary and the saints. This is not worship, but honor given to those whom God has exalted.

Third Commandment: Remember the Sabbath day, to keep it holy

“Remember the Sabbath day, to keep it holy. You shall labor six days, and do all your work, but the seventh day is a Sabbath to Yahweh your God. You shall not do any work in it, you, nor your son, nor your daughter, your male servant, nor your female servant, nor your livestock, nor your stranger who is within your gates;
— Exodus 20:8-10

The Catholic Church observes the Lord’s Day on Sunday, the day of Christ’s resurrection, as the fulfillment of Sabbath rest. Catholics are obliged to participate in Mass and to refrain from unnecessary work that hinders worship, family life, or service to those in need. This does not dismiss the Old Testament command. It sees Sabbath rest transformed and deepened in Jesus, who said, “The Sabbath was made for man, not man for the Sabbath” (Mark 2:27).

Fourth Commandment: Honor your father and your mother

“Honor your father and your mother, that your days may be long in the land which Yahweh your God gives you.
— Exodus 20:12

This command reaches beyond the family to include respect for legitimate authorities such as teachers, employers, civil leaders, and the Church. Catholics understand honor as love, gratitude, obedience when it is lawful, and care, especially for aging parents. The Apostle Paul echoes this as “the first commandment with a promise” (Ephesians 6:2). It also calls parents to live in a way that is worthy of honor.

Fifth Commandment: You shall not kill

“You shall not murder.

— Exodus 20:13

Catholic moral teaching upholds the dignity of every human life from conception to natural death. The command forbids murder, abortion, euthanasia, and any deliberate killing except in strictly defined cases of legitimate self-defense. It also calls Christians to reject anger, hatred, revenge, and any scandal that leads others toward spiritual death. The Catechism reminds us that “human life is sacred” (CCC 2258), rooted in the truth that we are made in God’s image.

Sixth Commandment: You shall not commit adultery

“You shall not commit adultery.
— Exodus 20:14

This commandment protects the beauty and fidelity of marriage. Catholic teaching extends it to all sexual sins, including fornication and pornography, because sexual intimacy belongs within marriage between a husband and wife. It also calls married couples to lifelong faithfulness as a sign of Christ’s unbreakable love for the Church (Ephesians 5:25-32). It also calls for purity of heart and modesty in thought, word, and deed.

Seventh Commandment: You shall not steal

“You shall not steal.
— Exodus 20:15

Beyond theft, this command speaks to justice in economic and social life: paying fair wages, honoring debts, respecting private property, caring for the poor, and avoiding fraud, cheating, and envy. The Catechism emphasizes the universal destination of goods: the earth’s resources are meant for all, even as lawful ownership is respected. It also calls for restitution when wrong has been done (cf. Luke 19:8, Zacchaeus).

Eighth Commandment: You shall not bear false witness against your neighbor

“You shall not give false testimony against your neighbor.
— Exodus 20:16

Truthfulness is the foundation of trust in any relationship. The Catholic tradition understands this as a prohibition of lying, perjury, rash judgment, detraction, and calumny. It also calls Christians to protect the good reputation of others unless a grave reason requires disclosure. Jesus, who called himself “the truth” (John 14:6), calls his followers to speak the truth in love and to avoid gossip and deception.

Ninth Commandment: You shall not covet your neighbor’s wife

"You shall not covet your neighbor’s wife."
— Exodus 20:17b (ESV); also Deuteronomy 5:21a

In the Catholic listing, this command is separated from the coveting of material goods so that the interior sin of impure desire can be named clearly. This command addresses lustful thoughts and intentions and calls for purity of heart. Jesus reinforced it in the Sermon on the Mount: “Everyone who looks at a woman with lustful intent has already committed adultery with her in his heart” (Matthew 5:28). Battling such desires calls for prayer, custody of the senses, and modesty.

Tenth Commandment: You shall not covet your neighbor’s goods

"You shall not covet your neighbor’s house… or anything that is your neighbor’s."
— Exodus 20:17a, 17c (ESV); also Deuteronomy 5:21b

This commandment forbids greed, envy, and the restless desire for more possessions. The Catechism teaches that covetousness is one of the roots of theft, fraud, and violence. Instead, Catholics are called to cultivate contentment, gratitude, and detachment from material things, echoing St. Paul: “I have learned in whatever situation I am to be content” (Philippians 4:11). It also invites a generous heart toward those in need.

Living the 10 Commandments in Daily Catholic Life

For Catholics, the Ten Commandments are not a checklist for earning salvation. They are a gift that shows how to live in right relationship with God and neighbor. They trace the path of love that Jesus summarized: “You shall love the Lord your God with all your heart … You shall love your neighbor as yourself” (Matthew 22:37-39). The Apostle Paul also says the commandments are summed up in love (Romans 13:9-10).

Here are a few practical ways to live the Decalogue:

Examine your conscience each day with the commandments as a mirror.
Receive the Sacrament of Reconciliation regularly, confessing sins against these commands and asking for grace to grow.
Make Sunday Mass and the Eucharist the heart of the week, honoring the Third Commandment.
Choose media, entertainment, and friendships that support purity of heart and mind.
Practice generosity and justice in your workplace and community.

The commandments are a sure guide, but we need God’s grace to keep them faithfully. As the psalmist prayed, “Open my eyes, that I may behold wondrous things out of your law” (Psalm 119:18).

The Ten Commandments are not merely ancient rules. They are a living word that leads you into freedom and deeper love for God. Whether you meet them in the Catholic numbering or another tradition, the Spirit uses these words to shape your heart. Take one commandment this week and meditate on it. Ask the Lord to show you how to live it more fully. Let God’s law become your delight and your guide.

Questions people ask

Why do Catholics have a different numbering of the Ten Commandments?

The difference comes from two ancient traditions. Catholics follow the numbering used by St. Augustine in the fourth century, which combines the commands about other gods and graven images into one and splits the coveting prohibition into two. Protestant and Orthodox churches generally follow the earlier numbering found in Origen and the Septuagint, which separates the first two commands but combines the coveting into one. Both traditions include every word of Exodus 20 and Deuteronomy 5, just grouped differently.

What are the 10 Commandments in the Catholic Bible?

The Catholic Bible contains the same Ten Commandments as any other Christian Bible, found in Exodus 20:1-17 and Deuteronomy 5:6-21. The words are identical; only the way Catholics number them differs. For example, 'You shall have no other gods before me' and the prohibition of carved images form the First Commandment in Catholic tradition, while many Protestant churches count the image command as a separate Second Commandment.

Where are the 10 Commandments listed in the Catholic Catechism?

The Catechism of the Catholic Church presents the Ten Commandments in Part Three, Section Two, covering paragraphs 2052–2557. Each commandment receives its own chapter with detailed explanation of its meaning, how it applies to moral life, and references to Scripture, the Church Fathers, and Church teaching.

Do Catholics worship statues and break the commandment about graven images?

No. The Catholic Church teaches that worship (latria) is due to God alone. Statues and images are used as visual reminders of holy persons, similar to carrying a photograph of a loved one. Catholics honor the person depicted but do not worship the image itself. The command against graven images (Exodus 20:4-5) is understood to forbid the worship of created things, not the proper use of art in devotion. The same Old Testament tells of God commanding the creation of cherubim for the ark (Exodus 25:18) and the bronze serpent (Numbers 21:8-9), indicating that images are not inherently sinful.

How do Catholics keep the Sabbath holy?

Catholics keep the Lord's Day, Sunday, as the fulfillment of the Sabbath command. They are obligated to participate in the Mass and to refrain from unnecessary work and activities that hinder worship, rest, or family joy. The Church teaches that Jesus' resurrection on the first day of the week transformed the Sabbath rest into a celebration of the new creation. The essence of the commandment — setting apart a day for God — remains, but it is now observed on Sunday (Acts 20:7; Revelation 1:10).
