(I am trying to type this on a tablet and the CM site is playing up, so forgive any typos and layout problems).
The TFP recently made a post which seems to contradict the Vatican response.
The Australian Church quotes a whole heap of documents to support it's claim. Notably, the oldest source is one from Pope Pius 12 in 1952, followed by Pope John 23 in 1963. It is interesting, though, that they have not quoted the Church fathers. However, they posit that
'The Catholic Church teaches the demands of human dignity always come before the national interest'.
TFP says 'Secondly, Saint Thomas teaches that immigration must have in mind the common good; it cannot destroy or overwhelm a nation'www.tfp.org.
I must admit I am inclined to take on what the Bishops teach rather than the TFP, but I think I will be shot down for looking as if I am a Cafeteria Catholic. Should we just go by what the Vatican teaches, and the International interperetations thereof, or should we simply take a liberal vs conservative viewpoint?
