In theory. The issue is we've seen exactly what happens in a Congress v. constitution showdown once the Congresspersons put their collective feet down. Congress eventually redefines the law in a way that favours them. Plain language won't stop them if they get serious; they aren't supposed to be regulating the US economy the way they do either and a lot of stuff the military-industrial complex does looks like it should be unconstitutional (like the spying and the secret courts).

On the one hand there is a clear and comforting consensus in the US that they aren't going to force religious mores on anyone. So I don't see how the Congress could or would try. But if we ever end up in a situation where the US Congress decides it wants to go straight Catholic I really don't see how it would fail. They've got far too much power and they'll eventually rotate in a compliant judiciary and then redefine what words mean so they can do it.

It is a bit difficult when dealing with such an out-there scenario, but if Congress decides the US military should do something wild then eventually the military is going to do it. The realistic protection is that by virtue of good system design there isn't a plausible scenario where Congress would want to impose Catholicism on the US population by force.
