In Mere Christianity, C.S. Lewis writes:
Do not be scared by the word authority. Believing things on authority only means believing them because you have told them by someone you think is trustworthy. Ninety-nine per cent of the things you believe are believed on authority. I believe there is such a place as New York. I have not seen it myself. I could not prove by abstract reasoning there the must be such a place. I believe it because reliable people have told me so. The ordinary man believes in the Solar System, atoms, evolution, and the circulation of the blood on authority — because the scientists say so. Every historical statement in the world is believed on authority. None of us has seen the Norman Conquest or the defeat of the Armada. None of us could prove them by pure logic as you prove a thing in mathematics. We believe them simply because people who did see them have left writings that tell us about them: in fact, on authority. A man who jibbed at authority in other things as some people do in religion would have to be content to know nothing all his life.
There are good reasons to accept many of the things we believe. But none of them are as good as the reasons we have to accept Jesus. How can we expect to know and believe truth if we don’t consider where authority truly comes from?
A Scientists come to us and says we should believe him because he personally studied a thing out. Scholars, politicians, judges, presidents, neighbors, loved ones, everyone does it. But who are they? They are only men, susceptible to the same sins of compromise that all men fall to.
And even if a person is right on a thing, the very thing they’re right about would itself testify for Christ. And if a man is against Christ then that thing in which he put his hope will betray him and side, as it always has, with Christ. Creation makes no allegiance to that which opposes the Creator, nor does it pretend to. It will oppose us if we are against the Living God.
As we examined in the previous post, Jesus’ witness have rightful claim to authority. We would do good to listen to them… and to listen to God.
Therefore, since we have so great a cloud of witnesses surrounding us, let us also lay aside every encumbrance and the sin which so easily entangles us, and let us run with endurance the race that is set before us, fixing our eyes on Jesus, the Author and Perfecter of faith, who for the joy set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God. For consider Him who has endured such hostility by sinners against Himself, so that you will not grow weary and lose heart.
