Our country’s determination to protect our southern border comes with tangible costs. We lose the talents, skills and dedicated labor of hundreds of thousands of productive immigrants. We lose their participation in our parishes — 40 percent of all growth in registered parishioners in Catholic parishes between 2005 and 2010 was from Hispanic or Latino/a Catholics, according to the Center for Applied Research in the Apostolate. We lose their attendance in our schools and engagement in our neighborhoods. We lose their diversity, one of the most positive traits of these United States.
