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).
Thanks for that info! Here in Oklahoma the Mormon Church in my area is doing an outreach into the illegal community which I thought was odd.
Most of the Catholics here that I know do not support the illegals, but then they go to the new Church across town not the older church that has a Mass in Spanish.
