Help refresh my memory! Is it the US Constitution, or The Bill of Rights, which prohibits religious tests for those holding public office? From Notary Publics to the US President. I see Mitt Romny's Mormonism is alarming some. Personally, I'd be more alarmed with another Roman Catholic. JFK was OK, and promised to not use the Presidency for that church's gain. However, looking around, I see that of 9 Supreme Court Justices, 5 are Roman Catholics. I see that in April, the Chaplain of the US House of Representatives resigned after 11 years of service. He was a Roman Catholic priest. In short order, the Roman Catholic speaker of the House, Ohio's Boehner, got another Roman Catholic priest the job. That is a church well connected, politically. Anyway, where is that prohibition against religious tests for public office?
