In this brief clip from his teaching series Defending Your Faith, R.C. Sproul explains why Christianity is different from every other religion.
I hear people say, “there is this underlining unity, we all believe the same thing.” That’s not true. What Muslims believe about what is good and the nature of redemption is radically different from what Christianity teaches, for example. Buddha was an atheist who simply claimed to be enlightened, Confucius talked about the veneration of ancestors—that’s a long way from the faith of the Scriptures. And what you don’t have in Buddhism and Islam, Confucianism, Shintoism, Taoism, and these other religions is an atonement. You don’t have a way of redemption that we have in Christianity, nor do you have a living Mediator. Moses is dead, Buddha is dead, Confucius is dead, and Muhammad is dead. There is no resurrection in these other religions. Christianity has elements to it, content to it that distinguish it from all other religions, and with that distinction comes the claim of Christ that it [He] is the only true way to God.
