What Are The Sacred Books Of Christianity

Introduction

The sacred books of Christianity form the foundation of the faith, shaping doctrine, worship, moral teaching, and everyday life for more than two billion believers worldwide. While most people instantly think of the “Bible,” the Christian canon actually consists of two major collections—the Old Testament and the New Testament—together comprising 66 books in the Protestant tradition, 73 in the Catholic tradition, and up to 81 in the Eastern Orthodox tradition. Understanding which texts are considered sacred, why they were selected, and how they differ among Christian denominations provides essential insight into the religion’s rich literary heritage and its continuing influence on culture, law, and personal spirituality.

What Counts as a “Sacred Book” in Christianity?

Definition of Sacred Scripture

In Christian theology, a sacred book is any written work that is regarded as divinely inspired and authoritative for teaching, reproof, correction, and training in righteousness (cf. But 2 Timothy 3:16). This concept of inspiration means that, although human authors penned the texts, God guided their thoughts and words so that the final product conveys divine truth.

Canon vs. Apocrypha

• Canon: The officially recognized set of books that constitute the Holy Scripture for a particular tradition.
• Apocrypha (or Deuterocanonical books): Writings that are included in some canons (e.g., Catholic, Orthodox) but excluded from others (e.g., most Protestant churches). They are valuable for historical and theological study but do not carry the same doctrinal weight in traditions that reject them.

The Old Testament: Roots of the Christian Faith

The Old Testament (OT) is essentially the Hebrew Bible, a collection of texts that predate Christianity but are considered prophetic foretelling of Christ’s coming. Its composition varies:

Major Divisions

1. The Pentateuch (Torah) – Genesis, Exodus, Leviticus, Numbers, Deuteronomy. These five books outline creation, the patriarchs, the Exodus, and the Law given to Moses.
2. Historical Books – Joshua through Esther. They narrate Israel’s conquest, monarchy, exile, and return.
3. Wisdom Literature – Job, Psalms, Proverbs, Ecclesiastes, Song of Songs. These works explore human experience, worship, and divine wisdom.
4. Prophetic Books – Isaiah, Jeremiah, Ezekiel, the Twelve Minor Prophets, and, for Catholics and Orthodox, the Deuterocanonical prophets (e.g., Baruch). They contain calls to repentance, visions of judgment, and promises of a Messiah.

Why the Old Testament Matters

• Christological Fulfillment: Christians read OT prophecies (e.g., Isaiah 53, Psalm 22) as predictions fulfilled in Jesus.
• Moral and Liturgical Foundations: The Ten Commandments, Psalms, and covenant theology still shape Christian ethics and worship.
• Covenantal Continuity: The OT establishes the covenant relationship between God and humanity, a theme that culminates in the New Testament’s “new covenant.”

The New Testament: The Life and Teachings of Jesus

The New Testament (NT) is uniquely Christian, documenting the life of Jesus, the birth of the early church, and the theological reflections of the apostles. Its 27 books are universally accepted across all major traditions.

Structure of the New Testament

1. The Gospels – Matthew, Mark, Luke, John. They provide four perspectives on Jesus’ ministry, death, and resurrection.
2. Acts of the Apostles – A historical sequel to Luke’s Gospel, describing the spread of the gospel through Peter, Paul, and other early missionaries.
3. Pauline Epistles – Romans through Philemon (13 letters). Paul’s letters address doctrinal issues, ethical living, and church organization.
4. General Epistles – Hebrews, James, 1 & 2 Peter, 1 & 2 & 3 John, Jude. These letters, written by various leaders, reinforce core Christian teachings.
5. Apocalypse – Revelation. A prophetic vision of the ultimate victory of God and the establishment of a new heaven and earth.

Core Themes

• Incarnation: God becoming human in Jesus Christ (John 1:14).
• Salvation by Grace: Justification through faith, not works (Ephesians 2:8‑9).
• The Kingdom of God: Present and future reign of God’s rule.
• Eschatology: The study of end‑times, culminating in the return of Christ.

The Deuterocanonical/Apocryphal Books

While Protestants label these texts “Apocrypha,” Catholics call them Deuterocanonical (meaning “second canon”), and Orthodox churches often refer to them simply as “the books of the Old Testament.” They include:

• Tobit – A story of piety, marriage, and divine intervention.
• Judith – A heroine who saves Israel through courage and faith.
• 1 & 2 Maccabees – Historical accounts of the Jewish revolt against Seleucid oppression, providing background for the celebration of Hanukkah.
• Wisdom of Solomon and Sirach (Ecclesiastical) – Reflections on wisdom, justice, and the fear of the Lord.
• Baruch – Contains a confession of sins and a promise of restoration.
• Additions to Daniel (Prayer of Azariah, Susanna, Bel and the Dragon) and Additions to Esther – Expand the canonical narratives with moral and theological insights.

These books are read and valued in Catholic and Orthodox liturgies, and they influence doctrines such as purgatory (2 Maccabees 12:46) and the intercession of saints.

How the Canon Was Formed

Early Collections

• Jewish Roots: By the 2nd century CE, the Hebrew canon (the 24‑book Tanakh) was largely settled.
• Christian Usage: Early Christians used the Septuagint (Greek translation of the Hebrew Scriptures) which included the Deuterocanonical books, explaining their presence in early Christian writings.

Key Milestones

1. Muratorian Fragment (c. 170 CE) – The earliest known list of New Testament books, missing Revelation and a few epistles.
2. Council of Hippo (393 CE) & Carthage (397 CE) – Regional synods in North Africa affirmed the 27‑book New Testament canon and the 46‑book Catholic Old Testament.
3. Council of Trent (1546) – The Catholic Church formally declared the Deuterocanonical books as canonical in response to the Protestant Reformation.
4. Reformation (16th century) – Reformers like Martin Luther advocated for a canon matching the Hebrew Bible, leading to the 39‑book Protestant Old Testament.
5. Eastern Orthodox Synods (7th‑9th centuries) – Varied regional canons resulted in the broader Orthodox list, later solidified by the Synod of Jerusalem (1672).

Criteria for Inclusion

• Apostolic Origin – Direct connection to an apostle or his close associate.
• Universal Acceptance – Widespread usage in liturgy and teaching across churches.
• Orthodox Consistency – Harmony with accepted doctrine and lack of theological contradiction.
• Liturgical Use – Regular reading in public worship.

The Role of Sacred Books in Christian Life

Personal Devotion

• Reading Plans: Many believers follow yearly reading plans that cover the entire Bible, fostering spiritual growth.
• Meditation: Psalms and the Gospels are frequently memorized and meditated upon for comfort and guidance.

Corporate Worship

• Lectionary Systems: Liturgical churches (Catholic, Anglican, Orthodox) use a three‑year cycle (or four for some Protestants) that selects passages from both Testaments for each Sunday.
• Sacraments: Baptism and the Eucharist are grounded in scriptural commands (e.g., Matthew 28:19, 1 Corinthians 11:23‑26).

Moral and Ethical Decision‑Making

• Law and Grace: The Ten Commandments (Exodus 20) provide a moral baseline, while Jesus’ Sermon on the Mount (Matthew 5‑7) expands ethical teaching.
• Social Justice: Prophetic books (e.g., Isaiah, Amos) inspire movements for poverty alleviation, racial reconciliation, and environmental stewardship.

Frequently Asked Questions

1. Why do Protestants, Catholics, and Orthodox have different numbers of books?

The divergence stems from differing views on the authority of the Septuagint versus the Hebrew Masoretic Text, as well as historical decisions made at various councils. Catholics and Orthodox retain the Deuterocanonical books because they were part of the early Christian scriptural tradition, while Protestants returned to the Hebrew canon during the Reformation.

2. Is the Bible the only sacred text for Christians?

For most denominations, the Bible is the sole normative source of doctrine. Still, the Catechism, Church Fathers’ writings, and ecumenical council decrees are considered important secondary authorities, especially in Catholic and Orthodox traditions.

3. How do scholars determine the original wording of ancient manuscripts?

Through textual criticism, scholars compare thousands of manuscript copies (e.g., Codex Sinaiticus, Codex Vaticanus) to identify variants and reconstruct the earliest attainable text. This science ensures modern translations reflect the most reliable wording.

4. What is the significance of the “canonical” label?

A canonical book is recognized as inspired and authoritative for faith and practice. Non‑canonical works (e.g., the Gospel of Thomas) may offer historical insight but lack doctrinal authority.

5. Can the canon change in the future?

Historically, the canon was closed after the 4th century for the New Testament and after the early councils for the Old Testament. Most Christian traditions view the canon as closed, meaning no new books will be added.

Conclusion

The sacred books of Christianity—the Old Testament, the New Testament, and, for many traditions, the Deuterocanonical/Apocryphal books—form a cohesive, divinely‑inspired library that guides belief, worship, and moral conduct for believers worldwide. Now, while the exact composition varies among Protestant, Catholic, and Orthodox churches, the core message remains: a narrative of creation, fall, redemption, and ultimate restoration through Jesus Christ. Understanding the historical development, theological significance, and practical application of these texts equips readers not only to appreciate Christianity’s literary heritage but also to engage more deeply with its timeless spiritual truths.
