The Canonization Process
The word "canon" comes from a Greek word meaning rule or measuring rod. In biblical usage it refers to the list of books recognized as authoritative scripture. The canon did not fall from the sky as a completed list. It emerged gradually, through a process that was sometimes contested, sometimes regional, and nowhere near as tidy as later tradition suggested. Understanding how the canon formed helps explain both why certain books are in and why others are not.
For the Hebrew Bible, the process of canonization is difficult to reconstruct precisely. The Torah (the first five books) had achieved something like canonical status by the 5th century BCE, as Ezra's public reading in Nehemiah 8 suggests. The Prophets were more slowly recognized. The Writings - the third section of the Hebrew canon - remained somewhat fluid longer than the others. A rabbinical discussion at Jamnia around 90 CE is sometimes cited as the moment the Hebrew canon was closed, but recent scholarship has questioned whether that meeting was a formal council or simply an ongoing conversation, and whether its decisions were as binding as once thought.
The New Testament canon took even longer to settle. The letters of Paul were circulating and being collected within decades of his death. The four Gospels achieved wide circulation by the 2nd century. But the full 27-book canon that Protestants and Catholics share was not universally agreed upon until the 4th and 5th centuries. Athanasius of Alexandria listed the 27 books of the current New Testament in his Easter letter of 367 CE - the earliest complete list that matches the modern Protestant canon. The councils of Hippo (393 CE) and Carthage (397 CE) affirmed this list for the Western church.
The criteria by which books were included or excluded were never formally codified but generally involved: apostolic authorship or connection (was the book written by or associated with an apostle?), widespread and ancient usage in the churches, and consistency with the rule of faith (did the book's teaching align with what the church recognized as orthodox?). Books like the Gospel of Thomas and the Shepherd of Hermas were used in some churches but did not make the final list. The decisions were historical, not simply theological, and understanding that makes the canon both more interesting and more honestly complex than a simple story of divine selection.
