Deacon Duncan uses two elegant metaphors to describe the nature of naturalism and religion, and why it’s a bad thing for religion to be as “broad” as it is, instead of converging.
Suppose there are several of us who wish to climb to the very top of Mt. Sinai. We all live in different parts of the world, so we are all a certain distance from each other. Also, because of our different locations, we are all approaching Mt. Sinai from different sides, and sadly, we are inexpert mountaineers, and we find that we must frequently backtrack and start over. But we learn as we go, and we share information with one another, and gradually we approach the top.
And there an interesting thing happens: though we started from different places, and approached Sinai from different sides, we find that the closer we all get to the peak, the closer we all get to one another. We are searching for something that actually exists in the real world, and that means we all have something objective in common. This common objective draws us closer to one another as we draw closer to it.
