Christians love Scriptural commands; it makes things easy. We weigh in on an issue by citing a verse (or five) and we’re done—ding! Next problem?
So it is with immigration. We surf through our New Testament and then pause, sighing thankfully that there is a verse that seems to deal with illegal aliens, or at least strangers: “The stranger that you invited inside, fed, and clothed his nudity…it was me, Jesus. When you rejected that stranger and left him imprisoned; you rejected me, Jesus1.”
Well, we blush; it’s not as good as an explicit command. The passage is totally about interaction at the personal level and it doesn’t offer anything in the way of “thou shall”—especially not on the national level.
Ignoring the other post-worthy problems up above, I think there’s a proper goal in finding what Scripture says in regard to immigration. Surely, not for the purpose of finding a new law (wrongheaded, that), but for the purpose of discovering operating principles.
For that, we need to construct a thought model.
