Here’s an excerpt:
The early Christians did not, then, first form a rival “canon” of “new books” which came only gradually to be accounted as of equal divinity and authority with the “old books”; they received new book after new book from the apostolical circle, as equally “Scripture” with the old books, and added them one by one to the collection of old books as additional Scriptures, until at length the new books thus added were numerous enough to be looked upon as another section of the Scriptures.
