📖 Biblical Definition
Scripture affirms that God gave humanity the capacity for rational thought — we are made in His image and called to love Him with all our mind (Matthew 22:37). Reason is a good gift of creation. However, reason is fallen, finite, and dependent — it is not autonomous or self-sufficient. "The fear of the LORD is the beginning of wisdom" (Proverbs 9:10). Reason rightly functions under the authority of revelation, not as a judge over it. Paul warns against those who are "always learning and never able to arrive at a knowledge of the truth" (2 Timothy 3:7) and declares that "the wisdom of this world is folly with God" (1 Corinthians 3:19).
📜 Webster 1828 Definition
REASON: The cause, ground, principle, or motive of anything said or done; that faculty of the mind by which it distinguishes truth from falsehood.

REA'SON, n. [L. ratio.] 1. That which is thought or which is alleged in words, as the cause or motive of opinion or determination. 2. The faculty of the mind by which man is enabled to deduce consequences from premises. Note: Webster valued reason highly but understood it as operating under divine authority — his dictionary is permeated with the assumption that revelation is the foundation upon which reason builds, not the reverse.
📖 Key Scripture
• Proverbs 9:10 — "The fear of the LORD is the beginning of wisdom, and the knowledge of the Holy One is insight."
• 1 Corinthians 1:20-21 — "Has not God made foolish the wisdom of the world?"
• Colossians 2:8 — "See to it that no one takes you captive by philosophy and empty deceit, according to human tradition."
⚠️ Modern Corruption
Sola ratio is the operating principle of liberal theology and secular culture alike.

The Enlightenment enthroned autonomous reason as the final judge of all truth claims — including those of Scripture. If a biblical teaching does not pass the bar of human reason, it is rejected: miracles are impossible, resurrection is mythological, the virgin birth is prescientific, and divine judgment is morally unacceptable. Liberal theology adopted this framework wholesale, producing "Christianity" stripped of everything supernatural. The result is a religion made in man's image — a God who conveniently agrees with contemporary intellectual fashion on every point. The Bible is clear: reason is a servant, not a master. It is a tool for understanding revelation, not a tribunal for judging it. The moment human reason sits in judgment over God's Word, man has made himself God.
Usage
• "Sola ratio enthroned human reason as the judge of divine revelation — and produced a God who conveniently agrees with modern intellectuals on every point."
• "The Reformers used reason to understand Scripture; the Enlightenment used reason to overrule it."
