And he said, 'Then I beg you, father, to send him to my father's house--for I have five brothers--so that he may warn them, lest they also come into this place of torment.' But Abraham said, 'They have Moses and the Prophets; let them hear them.' And he said, 'No, father Abraham, but if someone goes to them from the dead, they will repent.' He said to him, 'If they do not hear Moses and the Prophets, neither will they be convinced if someone should rise from the dead.'" (Luke 16:27-31, ESV) The rich man asked Abraham to send Lazarus back from the dead to warn his brothers about the awfulness of where he (the rich man) was now residing because he was under the impression that the Bible wasn't self-authenticating. The rich man thought that something more was necessary in order to convince his brothers about the reality of which the Bible speaks, and that if Lazarus was resurrected from the dead to go and warn them, then his brothers would listen and be convinced. But Abraham replied that even if someone was to rise from the dead to go and warn them they still wouldn't listen if they weren't previously prepared to listen to Moses and the Prophets. So this parable teaches that for those who are Christ's sheep the bare Word of the Scriptures is all that's needed to convince them of the truth of that which it teaches, because it authenticates itself in the minds of Christians as being the Word of God, and doesn't need any external confirmation about its validity. So the Catholic idea that you have to have a committee of the faithful to decide what is and what isn't the Word of God isn't correct, because God's Word is in itself self-authenticating to Christians.
