I've been listening to Bart Ehrman's podcasts about the Bible, provocatively entitled Misquoting Jesus. Prof Ehrman has forgotten more about the New Testament than I am ever likely to know, and I have learned a lot from them. His explanation of how the "lost chapter" of Mark's Gospel was discovered; and why it is very probably a forgery is great fun.
But occassionally, his language wrankles slightly. Ehrman has a tendency to refer to the apocryphal gospels -- the Christian texts by people other than Matthew, Mark, Luke, John and sometimes Paul -- as "books which never made it into the Bible."
Which is literally true. Oliver Twist is a book that never made it into the Complete Works of William Shakespeare, and Sailor on the Seas of Fate is generally excluded from the Harry Potter series. But there is a danger that a listener could infer that Judas and Thomas and Peter and that huge body of second and third century fan-fic might have become of the Bible.
I suppose there could have been a world where "the Bible" never stopped growing: where books written by the disciples of the disciples of the disciples had the same status as the big Four (or sometimes Five). Maybe the Sermons of John Wesley and the Broadcast of C.S Lewis might have been canonised as part of the Twenty Eighth Testament. Don't the Quakers have something like that -- a collection of "testimonies" that each generation adds to?
But the phrase "never-made-it-into" plays into the story that Once Upon a Time (TM) there was a big pile of books, all equally valid or equally invalid, and then one day an unruly mob armed with surprise, fear, nice red uniforms and an almost fanatical devotion to the Pope unexpectedly burst in and arbitrarily deleted the ones they happen not to like.
Ehrman, obviously, doesn't remotely believe this story. He is clear and interesting and helpful about where the canon actually came from. The catholic church didn't have an official list of all the books that were definitively in the Bible until as late as the sixteenth century. But everyone who called themselves a Christian had been working from the same list for about thirteen centuries before that. The 1546 decree only came about because Martin Luther was making noises about excluding James and Revelation.
But I think it's the story Richard Dawkins and Dan Brown and the journalists who got excited about the Gospel of Mary hoax believe in. Thomas and Mark are "the same kind of thing" and only random chance or inquisitorial suppression put one between big black leather covers and relegated the other to the Loeb Ancient Greek Texts series.
When Ronald Knox started to talk about the Sherlock Holmes "canon" in the 1930s he was making a scholarly religious joke. But once you've stopped laughing, the Holmes canon isn't particularly hard to define: it's whatever Conan Doyle wrote. Fifty something stories and a handful of novels. I am told that some people play a meta-game where, for example, Laurie King's Mary Russel books are treated as canon, but that's all part of the joke.
Comic book canon is quite a bit more fiddly. There are an awful lot of Spider-Man comics out there and it takes a monumental act of faith to believe they are all true at the same time. But if I say "Is Captain America canonically Irish?" or "Is Jimmy Olsen canonically gay?" I think you understand the question. Captain America's heritage has been alluded to in the comic books themselves; Jimmy Olsen has only been said to be Superman's Very Special Friend in fan-fiction.
You might very well say that it doesn't make any difference; but you understand the question.
So: how, as readers, scholars, and adaptors, should we define the Tolkien canon?
