A must read for all Protestants and Catholics:
Solo scriptura is, according to Mathison, an unbiblical position; proponents of sola scriptura should uphold the claim that Scripture is the only infallible authority, but should repudiate any position according to which individual Christians are the ultimate arbiters of Scriptural truth. In this article we argue that there is no principled difference between sola scriptura and solo scriptura with respect to the holder of ultimate interpretive authority, and that a return to apostolic succession is the only way to avoid the untoward consequences to which both solo scriptura and sola scriptura lead.
