[Jacquerie]

I already noted that I doubt that phrase gives Congress the authority to deny jurisdiction.

Sorry, the Constitution gives Congress that authority. It is rarely used as our ccritters would rather the unelected courts make difficult decisions.

You know, I would say this:
Congress has the right to protect the free exercise of Religion.

I fall back on the Constitution:

1st Amendment:
Congress shall pass no law to establish a religion, or limit the free exercise thereof

Congress can not pass a law that tells you and me which church or religion to believe in; and Congress can not limit the free exercise of Religion (unless the religion tells you to harm another). Meaning, if Congress said you can not say God then they would be passing a law that limits the free exercise of religion. Saying God or putting religious symbols on Public property does not establish a religion. It takes a law from Congress to do that. But Congress should never pass a law that stops people from expressing themselves. That to me would seem unconstitutional.
