How and When Was the Bible Compiled into One Book?
In the early centuries, Scripture wasn't a single bound book on a shelf. It was a collection of scrolls and letters that were read in Jewish synagogues and, later, in Christian communities.
The Old Testament books, including the Deuterocanonical writings, were already part of the Greek translation of Scripture known as the Septuagint, which was widely used at the time of Jesus and the apostles. The New Testament writings began to circulate after the Resurrection, with letters from Paul passed from one church to another and the Gospels carefully preserved.
By the 4th century, Church leaders recognized the full canon of 73 books we know today in the Catholic Bible.
Centuries later, the invention of the printing press changed everything. The Gutenberg Bible in the 1450s made it possible for Scripture to be copied more quickly, shared more widely, and treasured in homes as well as churches.
What began as scattered scrolls slowly became the unified, complete Bible with all of the best books in the Bible that Catholics read and cherish today. And for those who want to keep God's Word close in daily life, scripture gifts with favorite verses can be a beautiful reminder of the same truths passed down through centuries.

Conclusion
The Catholic Bible contains 73 books, 46 in the Old Testament and 27 in the New Testament, and each one plays a part in telling the story of God's love and faithfulness. We've seen how these writings were preserved, recognized, and brought together into the complete collection used in the Church today.
Understanding the structure of the Bible helps us appreciate both its depth and its unity, from the Law and the Prophets to the Gospels and the Epistles.
