Church Going

In Larkin's "Church Going," a scene is described as being as a beautiful empty church. The church is being examined by an un-belonging biker; the biker seems to be familiar with the church's innards and examines them thoroughly. He seems not to appreciate the church for its religious aspects, but for its features and architecture. He then begins to examine the reason for the church in the first place, he seems to have almost a sad tone when describing that the church has been reduced to a once a week, superstitious ceremony along with weddings and baptisms. It seems that he can recall when religion played a larger role in society. He has realized that belief is dieing, and he begins to wonder what will happen when it is dead. In particular, what is going to happen to the building after belief has disappeared?
