Much as I hate to agree with the Left, what's wrong with "Upon my honor, and under penalty of perjury, I so do swear."

It's not so much "agreement with the left" as it is seeking supremacy of law over religion. The law fancies itself to be the ultimate force on earth.

"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof."

If you are a strict Constitutionalist, you must acknowledge that, in the first sentence of the first amendment, the founding fathers did indeed make the law supreme to religion in this country. We have total religious freedom- within the boundaries of civil law.
This is why I'm so concerned that we put strict constructionalists on the SCOTUS- if the Justices fail to follow the constitution, we can be deprived of any of our rights.
