Places of sanctuary date to Biblical times. When the twelve tribes of Israel were sent to the Promised Land, the Levites were the one tribe not given a specific area. Instead their people were distributed throughout the land, in forty-eight cities that would become part of their heritage. Six of those cities were designated as places of refuge – principally for those who had committed murder unintentionally. That concept of forgiveness and protection in the Jewish faith descended to Christianity, where sinners are told they can find refuge in Christ. Consequently, churches and synagogues have long provided sanctuary.
In the United States, sanctuary cities (formed in the 1980s) were to shelter illegal immigrants from federal immigration laws. Like so many ideas coming from the Left, this one, while well intentioned, has in practice served to protect criminals as well as hapless illegal immigrants who are otherwise innocent.
