A "Radical" Thought by C.S. Lewis in Mere Christianity

This is the whole of Christianity. There is nothing else. It is so easy to get muddled about that. It is easy to think that the Church has a lot of different objectives -- education, building, missions, holding services. The Church exists for nothing else but to draw men into Christ, to make them little Christ's. If they are not doing that, all the cathedrals, clergy, missions, sermons, even the Bible itself, are simply a waste of time. God became Man for no other purpose. It is even doubtful, you know, whether the whole universe was created for any other purpose. It says in the Bible that the whole universe was made for Christ and that everything is to be gathered together in Him.
