"One Federalist called Jefferson the “great arch priest of Jacobinism and infidelity.” The Connecticut Courant suggested he might be a secret Jew or Muslim. It complained that no one seemed to know “whether Mr. Jefferson believes in the heathen mythology or in the alcoran (Quran); whether he is a Jew or a Christian; whether he believes in one God, or in many; or in none at all.”
There was talk at the founding of turning the United States into an officially Protestant nation, and during debates over the Constitution, some in the states raised the specter of a Catholic, “infidel,” or “Turk” (an epithet for “Muslim”) holding office. But the founders wisely decided on a godless Constitution with no religious tests for national office."
