You might interpret me differently if you read the first piece in this series.
The Bible is a complex text with many virtues. The Book of Revelation, however, is not where I want to draw my underlying assumptions about which disasters to prepare for. More than once I have had the experience of reading a sensible-sounding post on a prepper’s blog, only to find a few paragraphs in that s/he was gravely concerned about the literal arrival of events foretold by St. John the Divine. For some readers, that’s a draw, which is fine.
The readers I’m trying to reach, the ones who prefer to think about disaster on the policy level but haven’t prepared for the next hurricane on the household level, would likely be put off the whole project of learning how to save themselves (in the practical sense of the word save) by mentions of the Beast and the Woman Clothed in the Sun.
If you want to talk about the Sermon on the Mount, or Matthew 25:34–45, and the relevance of those parts of the Bible to how we take care of others when disasters strike, I’m right there with you, even though Christianity is not my path. If you want to talk about how Revelation shapes the way people imagine apocalyptic scenarios of all kinds, I could get into that conversation.
But anybody who would like to make a case that we should include the sun becoming black as sackcloth and the moon becoming as blood in the list of events to plan for, well, that reader has a vast network of writers and fellow readers who share his/her views, and they have many other places to go.
