By Msgr. Charles Pope, EWTN News - Catholic teaching says that we must balance between the duty of a nation to welcome immigrants, and the duty of immigrants to obey a nation’s laws... What’s in a wall? A lot of meaning to be sure, as the raging debate in the U.S. shows. I’ve been asked if there is a Catholic position on the building of a wall along our southern border. There is no Church teaching on such a matter, and I don’t think that there should be.
