I remember when it was prudent to refrain from invoking the Bible or testifying how Christian, or what type of Christian, a candidate might be. John F. Kennedy, a Catholic, proclaimed he wouldn’t be beholden to the Vatican were he elected president; he would serve as president according to the Constitution.
It was understood this was how it is. After all, governmental powers and limitations are constructed by the Constitution, not the Bible. Rick Santorum and Newt Gingrich would have you believe government should be run in accordance with biblical principles.
This is opposite what the founding fathers imagined. The “no religious test” clause, Article VI, paragraph 3 of the Constitution, affirms this. Had they intended to promote religion as an arm of government or government as an arm of religion, they would’ve specified it. They didn’t.
To the contrary; they were careful to discourage church-state relationships. Santorum and Gingrich pompously proclaim otherwise.
