When was the Bible completed in its final form?

Pastor Mike’s Answer (edited)

The Bible was complete when the final word of the final inspired book was written. The last New Testament book was likely Revelation, written by the apostle John near the end of the first century. At that moment, the full collection of God-breathed Scripture existed, even though copies still had to be circulated and recognized throughout the churches.

The early church did not create or authorize the canon at the Council of Nicaea. Christians recognized the books God had inspired. Early Christian writings quote the New Testament extensively before that council, showing that the churches were already receiving and using these books as Scripture.

The Old Testament was written primarily in Hebrew, with some Aramaic, over roughly a thousand years. The New Testament was written in common, or Koine, Greek. Questions about canonicity concern how believers recognized these writings as the authoritative measure of Christian doctrine.
