The Catholic Church’s stand on illegal immigration has been consistent since about the 4th century AD. It’s one of the things that brought down the Roman Empire (all those wonderful future converts streaming across the frontiers) and it could destroy the US too.
I had no idea how long the Church had that mindset. I know they have run an underground railroad for Illegals for decades. There was an article here not long ago about the Church on Catalina Island offering space for a Mexican Consulate to issue their Matricular IDs from.
