““At the time, I thought my colleague’s views sounded absurdly legalistic: if Christianity had lost all its living and breathing followers in Tunisia (say), what did it matter if the institutional minutiae survived? But on reflection, I think he was making a worthwhile point about the time span of human history. The scriptures of many religions remind us that the divine does not necessarily work according to our concepts of time. As the Psalmist declares, “[A] thousand years in your sight are just like yesterday when it is past, like a watch in the night.” Perhaps only our limited awareness of time leads us to think that the ruin of a church has happened “forever,” when all we mean is that, by our mortal standards, we can see no chance of it being reversed. In fact, religions are like biological organisms, which do not become extinct just because they are driven from a particular environment. Provided they continue to exist elsewhere, they might well return someday to recolonize. And often, in the human context, memories of that historical precedent help shape the new settlement.””
