If you think that's the position of the Catholic Church, it may take a little tap dancing to reconcile it with this sentence in the Catechism:
2241
Political authorities, for the sake of the common good for which they are responsible, may make the exercise of the right to immigrate subject to various juridical conditions, especially with regard to the immigrants' duties toward their country of adoption.
Now....the American bishops....well, they have all sorts of ideas.
I spent several years working at the UN alongside Catholic groups on family issues. I met with Cardinal Martino at the UN Mission. I have hosted the Catholic delegate to UN meetings in my home.
I noticed that they always got very quiet when immigration issues were on the table, and usually took the pro-immigrant position, if they took any position at all. I think I remember being told that the Catholic position was the people should be able to immigrate wherever they want.
Did I misunderstand?
