Many Christians wonder about the differences between Catholic and Protestant Bibles, especially when they notice Catholics reading from books they’ve never heard of. This question touches something deeper than mere curiosity—it speaks to our desire for unity in the body of Christ and our hunger to understand God’s complete revelation.
The Catholic Bible contains the same 66 books that Protestant Christians read, plus seven additional books called the Deuterocanonical books. These include Tobit, Judith, Wisdom, Sirach, Baruch, and First and Second Maccabees, along with additional sections in Daniel and Esther.
What Bible Do Catholics Read?
Catholics read a 73-book Bible that includes the Protestant Old and New Testament plus seven additional books known as the Deuterocanonical books. The most commonly used Catholic translations include the New American Bible (NAB), the Revised Standard Version Catholic Edition (RSV-CE), and the Douay-Rheims Bible.
The Structure of the Catholic Bible
The Catholic Bible divides into the same two major sections as Protestant Bibles: the Old Testament and the New Testament. The New Testament remains identical across all Christian traditions, containing the same 27 books from Matthew through Revelation.
The difference lies in the Old Testament, where Catholics include 46 books compared to the Protestant count of 39. These additional seven books were part of the Septuagint, the Greek translation of Hebrew scriptures that early Christians used extensively.
Popular Catholic Bible Translations
The New American Bible (NAB) serves as the official translation for Catholic liturgy in the United States. This translation balances scholarly accuracy with readability, making it accessible for both personal study and public worship.
The Revised Standard Version Catholic Edition (RSV-CE) provides another widely respected option. This translation maintains the literary beauty of traditional English while incorporating modern scholarship and including the deuterocanonical books.
Some Catholics still cherish the Douay-Rheims Bible, which served the English-speaking Catholic world for centuries. Though its language sounds more formal by today’s standards, it carries deep historical significance and spiritual richness.
Understanding the Deuterocanonical Books
The term “deuterocanonical” means “second canon,” but this doesn’t imply these books hold secondary importance in Catholic teaching. Rather, it acknowledges that these books faced more debate in early church history regarding their inclusion in Scripture.
These seven books offer profound spiritual insights and historical context. The Book of Wisdom contains beautiful passages about God’s love for creation, while Sirach provides practical wisdom for daily living that rivals Proverbs in its depth.
Why the Difference Exists
This difference traces back to different decisions made during the Protestant Reformation in the 16th century. Protestant reformers chose to follow the Hebrew canon that was finalized by Jewish scholars, while Catholics maintained the longer canon that had been used by Christians for over a thousand years.
Early Christian communities, including the apostles themselves, frequently quoted from the Septuagint, which included these disputed books. The Council of Trent in 1546 formally declared these books as fully canonical for Catholics, settling the question definitively within Catholic teaching.
Practical Differences in Daily Reading
When Catholics read their Bibles, they encounter stories and teachings that Protestant Christians might not know. The heroic account of the Maccabean martyrs provides powerful examples of faithfulness under persecution, while Tobit offers a beautiful narrative about God’s providence and the importance of charitable giving.
These books contain passages that support distinctly Catholic doctrines, such as prayers for the dead found in Second Maccabees. This creates a richer tapestry of biblical support for Catholic teaching and practice.
The Lectionary Connection
Catholic Mass includes readings from these deuterocanonical books throughout the liturgical year. Catholics who attend Mass regularly hear these scriptures proclaimed and explained, making them as familiar as any other biblical text.
This liturgical use means that Catholic biblical spirituality naturally incorporates wisdom from all 73 books. The rhythm of Catholic worship shapes how Catholics understand and apply Scripture in their daily lives.
Common Ground and Unity
Despite these differences, Catholics and Protestants share the vast majority of Scripture. The 66 books that all Christians accept contain the core of our faith—the life, death, and resurrection of Jesus Christ, along with the foundational teachings of Christianity.
Both traditions affirm that Scripture serves as God’s revelation to humanity and carries ultimate authority for faith and practice. Whether reading 66 or 73 books, Christians find the same Savior and the same call to love God and neighbor.
Opportunities for Growth
Protestant Christians can benefit from exploring the deuterocanonical books, even if they don’t accept them as Scripture. These writings provide valuable historical context and spiritual wisdom from the period between the Old and New Testaments.
Catholics, meanwhile, can appreciate the Protestant emphasis on the authority and sufficiency of Scripture. This focus encourages deeper engagement with biblical text and more thorough biblical literacy.
Choosing a Catholic Bible Translation
Catholics seeking a Bible for personal study should consider their reading level and spiritual goals. The New American Bible Revised Edition (NABRE) offers excellent study notes and maintains official approval for liturgical use.
For those who appreciate more traditional language, the RSV-CE provides beautiful prose while maintaining scholarly accuracy. Families with children might prefer the Good News Translation Catholic Edition for its clarity and accessibility.
Features to Consider
Study Bibles provide invaluable help for understanding difficult passages and historical context. Look for editions that include maps, concordances, and cross-references to enhance your study experience.
Many Catholics appreciate Bibles that include the Church’s liturgical calendar and connections between daily Mass readings. These features help integrate personal Bible reading with the broader rhythm of Catholic worship and spirituality.
Living the Word Together
The question of which Bible Catholics read ultimately points to something more important than book counts or translation preferences. God speaks to His people through Scripture, calling them to transformation and service regardless of which translation they hold.
Scripture’s power lies not in its page count but in its capacity to reveal Jesus Christ and shape human hearts. Catholics reading their 73-book Bible and Protestants reading their 66-book Bible both encounter the same risen Lord who calls them to faith, hope, and love.
Consider how you might use this knowledge to build bridges rather than walls with Christians from different traditions. What would happen if we focused more on applying the Scripture we share than debating the books that divide us?
Start reading your Bible today—whichever version you choose—with fresh eyes and an open heart. Let God’s Word accomplish its work in your life, transforming you into the image of Christ and equipping you for every good work He has prepared for you.
