A quote from William Gurnall on the authority of Scripture:
You must live by your own faith, not someone else's. Look as long and as hard as necessary to see truth with your own eyes. A building propped up by a neighbor's house is too weak to stand very long. So do not let authority from man, but rather evidence from the Word, decide your judgment. Man's conclusions are no stronger than a piece of scrap-wood bracing a building, but truth stands on the eternal foundation of solid rock - God's Word!~William Gurnall (The Christian in Complete Armour Volume 2, Chapter 1, Part 1).
Quote Scripture instead of man. Yet in doing this, be careful not to lean so far this way that you lose the proper balance. We must not condemn the judgment of an elder whose wisdom and learning command reverence. Surely God has placed the true path in this matter squarely between defying men and deifying them.
