Has God Revealed Himself in Other Religions
Karl Barth was lecturing to a group of students at Princeton. One student asked the German theologian "Sir, don't you think that God has revealed himself in other religions and not only in Christianity?" Barth's answer stunned the crowd. With a modest thunder he answered, "No, God has not revealed himself in any religion, including Christianity. He has revealed himself in his Son."
