Yes, I do believe that people with vastly differing belief systems can find a common ground. Let's say that there are two grown men. Man A is a Muslim while Man B is a Christian. While they are talking with one another, they discover that they have both lost one of their children from some sort of tragic incident that happened in the past. This deep connection will be used to sympathize for one another and will bring them together. What we need to do as people, are look past each others differences and find what makes us similar. This can result in people working together and becoming one, and will also bring more peace to the entire world.
The adjective elusive refers to something that is difficult to find or catch. Therefore, the excerpt from "The Catching of Unshelled Fish" suggests that the fish moves so energetically that is it troublesome to apprehend it, which makes it more fascinating.
