That’s the second time I have seen that! Beginning to think I need to be doing some research.
Always keep in mind that as a "eternal" institution chartered by God himself, the RCC likes to see itself as pre-National and pre-State, viewing states as temporary human creations. As an anti-Nationalist American patriot (there is a HUGE difference between nationalism as an ideology and love of one's country), I can respect that position.
I have a feeling that while many in the Church hierarchy intellectually respect the rule of law within nations, they nevertheless have their hearts with the poor (and Catholic/Christian) folks who cross our borders. The same is NOT true when it comes to Muslims pouring into Europe (for good reason).
