A Question to the Know-Nothings

One more thought on the Know-Nothing proposal to bar Catholics, by law, from hearing certain court cases. How, precisely, will a Catholic be identified for the purposes of this law?

At confirmation, will nominees be required to document their religious affiliation? And suppose a nominee refuses, citing some silly grounds like the 1st Amendment, or the Article VI ban on religious tests. Will the Congress then take it upon themselves to declare that the nominee belongs to a certain religion? Or will they just subpeona the nominee’s church, demanding to know if he or she is a member in good standing?

Or maybe, to be fair, we can just require all judges – heck, all Federal employees – to register their religion with the government.
