The story of Jesus sitting and debating the Law with rabbis reminds me of another debate that took place in a comparative religions conference, the wise and the scholarly were in a spirited debate about what is unique about Christianity. Someone suggested what set Christianity apart from other religions was the concept of incarnation, the idea that God became incarnate in human form. But someone quickly said, "Well, actually, other faiths believe that God appears in human form." Another suggestion was offered: what about resurrection? The belief that death is not the final word. That the tomb was found empty. Someone slowly shook his head. Other religions have accounts of people returning from the dead.

Then, as the story is told, C.S. Lewis walked into the room, tweed jacket, pipe, armful of papers, a little early for his presentation. He sat down and took in the conversation, which had by now evolved into a fierce debate. Finally during a lull, he spoke saying, "what's all this rumpus about?" Everyone turned in his direction. Trying to explain themselves they said, "We're debating what's unique about Christianity." "Oh, that's easy," answered Lewis, "it is grace."

The room fell silent.

Lewis continued that Christianity uniquely claims God's love comes free of charge, no strings attached. No other religion makes that claim. After a moment someone commented that Lewis had a point, Buddhists, for example, follow an eight-fold path to enlightenment. It's not a free ride.

Hindu's believe in karma, that your actions continually affect the way the world will treat you; that there is nothing that comes to you not set in motion by your actions. Someone else observed the Jewish code of the law implies God has requirements, and Islam's code of love does the same.

At the end of the discussion everyone concluded Lewis had a point. Only Christianity dares to proclaim God's love is unconditional. An unconditional love that we call grace.
