Many people assume the Bible appeared fully complete — but in reality, the Bible was formed gradually over centuries. Catholics believe God inspired Scripture, and the Church recognized which writings truly belonged in the Bible.

The official list of inspired books is called the Canon.

What the Word “Canon” Means

“Canon” means a measuring rule — the official collection of books considered inspired by God. These books were used consistently in Christian worship and teaching.

How the New Testament Was Formed

In the early Church, Christians had:

• Oral teaching from Apostles
• Letters written to communities (like Paul’s letters)
• Gospels telling the life of Jesus
• Other writings (some true, some not)

The Church had to discern what was truly apostolic and inspired.

How the Church Recognized the Canon

Catholics believe the Church recognized Scripture through:

• Apostolic origin (connected to Apostles)
• Consistency with Christian faith
• Widespread use in worship
• Church discernment guided by the Holy Spirit

By the late 4th century, the Church had clearly identified the New Testament books used today.

Why This Matters Today

Understanding Bible formation builds trust and clarity:

• The Bible came from real history, not myth.
• Christians preserved Scripture at great cost.
• The Church protected truth against false writings.
