That's all well and good, of course, for theological discussions. But when it comes to concrete, "particular" matters of politics, that just doesn't cut it. The Church speaks to us in broad, general terms. It tells us things like: "It is not true that some races of men are naturally inferior to others: for all men have been created in the image and likeness of God." Again, it will tell us things like: "There is, among men, a natural right to migrate."
I could go on, but I think you will understand my meaning.
What does these mean in the particular circumstances? That's a tricky issue which requires political prudence (which, let us note, is a virtue). In the concrete instances here and now, how do we bring 1. the right of a nation-state to safeguard the well-being of its own citizens with 2. the general natural right to migrate...how do we bring these to bear, I ask, with respect to this country, with respect to these migrants, etc?
