Who decided which books belong in the Bible?

The church recognises God's Word; it does not give it authority.

THE STARTING ANSWER

God gives Scripture its authority. The church receives and recognises the books he inspired; it does not make them divine by voting. The history of that recognition includes discussion and disagreement, and must be studied through actual witnesses. The canon was not invented at Nicaea.

FOLLOW THE REASONING

From the claim to the conclusion.

Scripture is God's gift, not merely a collection of texts a community finds useful.

  • 2 Timothy 3:16–17

Peter refers to Paul's letters alongside the other Scriptures.

  • 2 Peter 3:15–16

Athanasius's Festal Letter 39 lists the 27 New Testament books we receive today.

  • Athanasius of AlexandriaFestal Letter 39, section 5

Historical lists document recognition. They do not create the authority that belongs to God's Word.

  • Michael J. KrugerThe church's recognition of authoritative books
  • Westminster1.4

Use a historical witness within its scope

Athanasius distinguishes canonical books from other recommended reading. We cite his New Testament list as historical evidence, not as an endorsement of every detail of his Old Testament list or his theology.

  • Athanasius of AlexandriaSections 4–7

Be clear about our canon

This library follows the 66-book Protestant canon expressed in Westminster. Its account of the Old Testament differs from the Roman Catholic canon. We do not describe that difference as a mere interface choice or imply that citing a Catholic writer removes it.

  • Westminster1.2–3

TAKE THE OBJECTION SERIOUSLY

Did a council simply choose the books that supported its power?

Name the council and examine the records. Kruger's account distinguishes the prior use of books from later ecclesiastical recognition and explains why attributing the New Testament canon to Nicaea fails.

  • Michael J. KrugerThe NT canon was not decided at Nicaea

A short guide is not a complete history of every book's reception. Human testimony can help us, while the authority and ultimate assurance of Scripture rest in God and his Spirit.

Are you asking how the church recognised the books, or what gives those books authority?
