Some illegal immigrants may CALL themselves Catholic, but look at the Church attendance rates in Mexico -- the lack of religion down there would be on par with Europe if it weren't for widespread heretical superstition south of the border. Most Central American countries are now only about half Catholic by population, if that -- Guatemala in particular has seen a huge surge in the number of Protestants.
The bishops are in this only for the tax money they can suck in.
Catholic charities are helping the Muslim invasion also, I suspect for the money.
The catholic church and other social justice heretics will get their just desserts soon enough. None of us will live to see the end of islam in north america.
Social Justice is not Christianity - is is an ugly stick for the sole purpose of hijacking the great commission. Robbing peter with high taxes to pay for a welfare state is the end result of heretical social justice.
