I think the Roman Catholic Bishops have turned a blind eye to this...they have forgotten that any secular government too, has a moral charge of its own, foremost of which is to provide for the safety and well -being of its citizens.
I think this is probably the most valid argument with the Archbishop's statement. There is a difference between the objectives of a government and the objectives of a church. The government does have an obligations to protect its citizens, which I believe is driving the immigration legislation. The Archbishop is focusing on the human dignity of each person and the protection of families without regards to citizenship, which is driving its opposition to this leglislation. There are plenty of economic and security reasons for the governments stand. There are also plenty of biblical reasons to support the Archbishop's point of view. Neither is wrong. This is how the system was designed to work.
