I found startling the point that society is moving torward the view that all religious belief is personal, that faith should not be held as a perspective on an external truth (Otherwise, one might say that another man is wrong in his beliefs). What it shows is that Postmodernism was already at work even in his time, though Modernism was considered the driving force behind the two World Wars and the Holocaust.
Otherwise, it is an amusing tale of two enemies who just can't seem to find a private place where they might kill each other. If it isn't the interference of people, then it's the interference of nature. The plot is absurd enough to point at the fatalism behind it.
