The Bible is being increasingly used to “prove” what a moral, ethical, spiritual, Jewish or Christian (take your pick) stance on US immigration policy would look like. More often than not, such Bible thumping generates more heat than light. But it’s especially interesting since the Hebrew Bible’s commands that we welcome strangers, may not include today’s illegal aliens at all.
The Hebrew Bible mentions obligations to so-called strangers on numerous occasions. The message is pretty much always the same and perhaps best summed up by the words of Leviticus 19:33-34, When a stranger dwells among you in your land, do not taunt him. The stranger who dwells with you shall be like a native among you, and you shall love him like yourself, for you were aliens in the land of Egypt–I am the Lord, your God.
But who that stranger is that deserves such equality and even love, is not necessarily a parallel to the millions of people who cross our borders illegally every year. Or perhaps it is.

The stranger of the Hebrew Bible is better understood as a resident alien, a non-citizen who agrees to abide by the laws of the community into which he or she has come. To that extent then, many if not most, illegal aliens in this country, would not qualify. On the other hand, there is no mention in the Bible of barriers to entry into the Israelite nation, so perhaps they do.
What seems clear from scripture (that itself a complex claim) is that loose borders or barriers to entry are only reasonable if accompanied by quite strict rules about participation once having arrived in the new community. That means that neither side in the current debate really understands what the Hebrew Bible intended.
Conservatives, generally obsessed with the “inappropriateness of rewarding illegal immigrants with any of the benefits of American life”, miss the fact that how someone came to join the Israelites had no bearing on their status within the community once they arrived. There really was a sense of community as sanctuary – precisely what those taking a hard line on immigration oppose.
Liberals however are just as off when insisting that biblical hospitality know no bounds and asked no questions – that it was an unqualified right with no attached obligations. In fact, like all ancient sanctuaries, there were many rules to be followed and norms to be upheld. In other words entry was open to all, and once in they were treated as equals, but demands were made and failing to meet those demands was grounds for exclusion from the community.

While other biblical texts and traditions could be introduced into the debate on immigration, based on those verses bearing directly on the issue, the path forward is actually pretty clear: how one got here is largely irrelevant, though the obligations that must be assumed in order to stay are significant.
Biblical “immigration policy” was not about maintaining the purity of the community or fear of withholding the benefits of membership, but it was quite clear about the obligations that needed to be met to enjoy the privileges (not rights) of such membership. It would be quite a step forward to see people actually look to that model for guidance instead of simply thumping their Bibles to prove that which they already believe anyway.
