I think you are right on this one. How can our country survive if we do not care who comes in, what they do, and what they take. That is insane policy. Even the church, every church, takes into consideration who their members are, what those members do, and how they represent their congregations. Otherwise,the supposed congregants can change and subvert the message of the church. It is the same for countries. I am certain most of the leaders in the government of Mexico would claim to be Catholic, but where is the humanity for those who are their illegally or non citizens that commit some petty crime and are thrown in a hell hole jail or prison? Arizona and Alabama are trying to solve a problem.
Who may come to the table is a really big deal in Christianity. The Cardinal certainly can’t plead ignorance of the concept.
