How to Study the Ten Commandments Verse by Verse — Catholic Guide

Studying the Ten Commandments in a Catholic way means more than memorizing a list. It means reading the commandments as Sacred Scripture, receiving them within the living tradition of the Church, and allowing one verse to illuminate another. In that spirit, the guiding principle is simple: Let Verses Explain Themselves.

The Ten Commandments, also called the Decalogue, appear most prominently in Exodus 20 and Deuteronomy 5. These two biblical presentations are closely related, yet each has its own literary setting, theological emphasis, and pastoral purpose. A Catholic study should therefore be biblical, catechetical, moral, and prayerful.

This guide explains how Catholic readers can approach the Ten Commandments: verse by verse, with attention to context, original-language roots, Catholic moral teachings, and the wider witness of Scripture.

1. Begin with the Catholic purpose of studying the commandments

Before opening commentaries or comparing translations, clarify the study's purpose.

The Ten Commandments are not merely ancient legal formulas. In Catholic theology, they are a privileged summary of the moral law, rooted in God's covenant with Israel and fulfilled in Christ. They teach the proper love of God and neighbor. They also provide a framework for examination of conscience, catechesis, moral formation, and spiritual growth.

A Catholic approach should hold together several dimensions:

• Biblical: What does the text say in Exodus 20 and Deuteronomy 5?
• Historical: Where do these commandments appear in the life of Israel?
• Theological: What do they reveal about God, covenant, worship, sin, and holiness?
• Moral: How do they shape Catholic moral teachings?
• Christological: How are they deepened and fulfilled by Jesus, especially in the Sermon on the Mount?
• Spiritual: How do they call the reader to conversion, virtue, and prayer?

2. Read Exodus 20 and Deuteronomy 5 in their full context

A verse-by-verse study begins before the first commandment appears. Read the surrounding chapters.

For Exodus 20, begin with Exodus 19. For Deuteronomy 5, begin with Deuteronomy 4 and continue into Deuteronomy 6.

Read both passages aloud: Exodus 20:1–17 and Deuteronomy 5:6–21. Note the opening words — God identifies Himself as the Lord who brought Israel out of Egypt.

3. Use a verse-by-verse notebook method

For each commandment, create five sections in your notebook: Text, Context, Key words, Cross-references (Proverbs, Psalms, Gospels), and Catholic moral application.

4. Compare Exodus 20 and Deuteronomy 5 carefully

Place the two passages side by side. One of the clearest examples is the Sabbath commandment — Exodus 20 connects it with creation; Deuteronomy 5 connects it with liberation from Egypt.

5. Read the Douay-Rheims alongside the Latin Vulgate

The Douay-Rheims translation has a special place in English-speaking Catholic biblical tradition because of its close relationship to the Latin Vulgate. Read the commandment in Douay-Rheims, then in the Latin Vulgate, identify major Latin terms, and note meaning carefully without forcing conclusions beyond the evidence.

6. Study each commandment negatively and positively

Each commandment contains both a prohibition and a positive call to virtue. Ask: What sin does this forbid? What virtue does it require?

7. Cross-reference with Proverbs and Psalms

For the commandment against false witness, Proverbs is particularly rich. For worship, reverence, and trust in God, the Psalms provide a prayerful lens. This approach allows wisdom literature and prayer to deepen moral understanding.

8. Read the commandments in light of the Sermon on the Mount

Jesus does not abolish the law; He brings it to fulfillment. The Sermon on the Mount (Matthew 5–7) deepens the commandments by addressing interior dispositions — murder connected with anger, adultery with lustful looking.

9. Include Catholic numbering and catechetical use

Catholic numbering differs from some Protestant traditions. The First Commandment combines worship of God and prohibition of idols. The commandment against coveting is divided into two. Always return to the biblical text in Exodus 20 and Deuteronomy 5.

10. Build a daily and weekly study workflow

Daily (20–30 min): Opening prayer → Read → Copy → Observe → Compare Douay-Rheims/Latin Vulgate → Cross-reference Proverbs/Psalms → Apply → Pray.

Weekly (60–90 min): Reread all notes, compare Exodus and Deuteronomy, consult a Catholic catechetical source, write a paragraph summary, make an examination of conscience.

11. Suggested ten-week structure

Devote one week to each commandment: worship and idols, the divine name, the holy day, father and mother, human life, marriage and chastity, property and justice, truth and witness, interior purity, detachment from goods.

12. Move from exegesis to examination of conscience

Catholic biblical study should lead to conversion. After studying a commandment verse by verse, ask: What does this reveal about God's holiness? What sin does it expose? What virtue is God calling me to cultivate?

13. Common mistakes to avoid

• Do not separate the commandments from grace.
• Do not read the commandments as merely negative.
• Do not isolate Exodus 20 from Deuteronomy 5.
• Do not use original-language study carelessly.
• Do not forget Christ and the Sermon on the Mount.
