As we prepare to celebrate the Fourth of July, it’s easy to forget that the Land of the Free wasn’t always so free for Catholics. In this morning’s New York Times, however, historian Kenneth C. Davis sets the record straight:

Often, the disdain for the foreign was inflamed by religion. Boston’s Puritans hanged several Friends after a Bay Colony ban on Quakerism. In Virginia, the Anglicans arrested Baptists.

But the greatest scorn was generally reserved for Catholics — usually meaning Irish, French, Spanish and Italians. Generations of white American Protestants resented newly arriving “Papists,” and even in colonial Maryland, a supposed haven for them, Roman Catholics were nonetheless forbidden to vote and hold public office.

Once independent, the new nation began to carve its views on immigrants into law. In considering New York’s Constitution, for instance, John Jay — later to become the first chief justice of the Supreme Court — suggested erecting “a wall of brass around the country for the exclusion of Catholics.”

We’ve come a long way. Haven’t we?
