Through the Bible - Canon
Not “cannon”! "Canon" means “rule” in the sense of a yardstick. All the books were “measured” and those considered inspired became part of the Bible. The canon of Scripture is now considered “closed” - no new additions have been or will be made. The Protestant Old Covenant is similar to the Jewish Bible, the main difference being the order of the books (see diagrams elsewhere).
It's important to remember that the Bible is a collection of 66 items (such as books, letters, gospel versions etc) published in one volume.
However some other books, e.g. Tobit, Ecclesiasticus, Judith, 1 and 2 Maccabees etc. are collectively known as the Apocrypha (from the Greek meaning "hidden"), These are recognised as canonical by the Roman Catholic Church, for example, but not by Protestant churches. As the Anglican Book of Common Prayer has it: And the other books (as Jerome saith) the Church doth read for example of life and instruction of manners; but yet doth it not apply them to establish any doctrine.
