Prioritising our own is not very Christian
The Bible seems to state an exactly opposite attitude. Instead, Deuteronomy 10:19 reads: “God shows love to the foreigners living among you and gives them food and clothing. So you, too, must show love to foreigners, for you yourselves were once foreigners in the land of Egypt.”
I am not a Catholic but perhaps Mr Sheahan is. His outgoing Pope declared in Caritas in Veritate: “Every migrant is a human person who, as such, possesses fundamental, inalienable rights that must be respected by everyone and in every circumstance.” I could go on at length. Immigrants are increasingly subject to this kind of reactionary speech. Emigration is often the only option for people around the world today. Ireland knows this too well.
