Scripture does not treat the religions of the world as equally valid paths to God. "I am the LORD, and there is no other, besides me there is no God" (Isaiah 45:5). Jesus declared, "I am the way, and the truth, and the life. No one comes to the Father except through me" (John 14:6). The Bible does compare false religions to the true worship of God — but always to expose them as idolatry, not to place them on equal footing. Elijah's contest on Mount Carmel (1 Kings 18:20-39) is the biblical model of "comparative religion" — a demonstration that the LORD alone is God and all others are nothing.
The term did not exist as a formal discipline in 1828. Webster defined religion as duties owed to the one true God.
RELIG'ION, n. Includes a belief in the being and perfections of God, in the revelation of His will to man, and man's obligation to obey His commands. Note: Webster did not treat all religions as equivalent — His definition assumed the God of the Bible as the true object of worship.
• John 14:6 — "I am the way, and the truth, and the life. No one comes to the Father except through me."
• Isaiah 45:5 — "I am the LORD, and there is no other, besides me there is no God."
• 1 Kings 18:21 — "How long will you go limping between two different opinions?"
• Acts 4:12 — "There is salvation in no one else, for there is no other name under heaven."
Comparative religion treats all faiths as equally valid, reducing Christianity to one option among many.
The academic discipline of comparative religion was designed with a built-in assumption: all religions are human attempts to reach the divine, and none can claim exclusive truth. This framework is itself a religious commitment — pluralism. When Christianity is placed alongside Islam, Hinduism, and Buddhism as one "tradition" among many, its exclusive claims are pre-emptively neutralized. The result is that students learn about every religion without being confronted by the claims of the one true God. Christians should understand other religions — not to affirm them but to expose their errors and proclaim the uniqueness of Christ.
• "The Bible's approach to comparative religion is Elijah on Mount Carmel: there is one God, and all others are frauds."
• "Studying world religions is valuable — but only when you begin with the truth that Jesus Christ is Lord and every other claim is measured against His."
