What was his answer?Yes he was,at the time when he was running for president that very question did come up about putting his catholic belief before the constitution.
It was quite a debate at the time and he answered it to the satisfaction of the American public and became elected.
That the constitution comes first and formost.
There's a problem with that too...if you're really a christian. God is always supposed to come 1st in your life, no matter what. It doesn't mean that you have to go around preaching to everyone, but if you're a truthful person you will admit that.
