Everything we do goes back to authority. This may seem like a statement with arms too big for its body, but allow me to elaborate. Two men, a Christian and a Hindu, see a child murdered. The Christian says it was a sinful act, while the consistent Hindu says that if a person could merely see this act in its entirety, the act would be seen as part of God. While both men saw the same act, they had different understandings of it, and these understandings come from their different authorities. This analogy holds true for every aspect of life, from science to mathematics to morality (and I am happy to elaborate for any who would ask me via email). If everything goes back to authority, what then is the Christian to do when authorities clash?
Paul gives us the answer in 2 Corinthians 10:4-5. He says the following:
(For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;) casting down imaginations, and every high thing that exalteth itself against the knowledge of God, and bringing into captivity every thought to the obedience of Christ;
These strongholds are the beliefs, and subsequently authorities, of unbelievers. Our weapons, the Scriptures, can tear them down by showing the consistency of Biblical revelation over against all other authorities. May God grant us the wisdom to use these weapons.
