Doctor, would you care to defend Calvin's ridiculous view on the self-authenticating scripture, somehow? A scriptural eveidence of such self-authentication would help.
"Nothings therefore can be more absurd than the fiction, that the power of judging Scripture is in the Church, and that on her nod its certainty depends. When the Church receives it, and gives it the stamp of her authority, she does not make that authentic which was otherwise doubtful or controverted but, acknowledging it as the truth of God, she, as in duty bounds shows her reverence by an unhesitating assent. As to the question, How shall we be persuaded that it came from God without recurring to a decree of the Church? it is just the same as if it were asked, How shall we learn to distinguish light from darkness, white from black, sweet from bitter? Scripture bears upon the face of it as clear evidence of its truth, as white and black do of their colour, sweet and bitter of their taste...
IOW, spirit recognizes spirit.
For what man knoweth the things of a man, save the spirit of man which is in him? even so the things of God knoweth no man, but the Spirit of God. Now we have received, not the spirit of the world, but the spirit which is of God; that we might know the things that are freely given to us of God." -- 1 Corinthians 2:10-12
"As for me, this is my covenant with them, saith the Lord; My spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed's seed, saith the Lord, from henceforth and for ever." -- Isaiah 59:21"But God hath revealed them unto us by his Spirit: for the Spirit searcheth all things, yea, the deep things of God.
