***NOTE- There was no Christian Bible until the late 4th Century, when Pope Damasus I put the Canon together, which was ratified at the Councils of Rome, Hippo, and Carthage.* Therefore, it would have been impossible for the first Christians to have used "Sola Scriptura", or the Bible Alone as a guide to salvation. It wasn't until the 16th Century that this doctrine was invented by Martin Luther.
