Can't help mentioning another newly discovered document, though not a religious one. Tom Weller, in his book CVLTVRE MADE STUPID (companion volume to Science Made Stupid) tells of the First Octavo of Shakespeare, which contains a couple of previously unknown poems. Although some have questioned the authenticity of these, linguistic analysis shows a Shakespearian vocabulary. In fact, the poems contain only two words unknown in Shakespeare's other works: thermonuclear and jazzercise.
