As National Migration Week winds down — when the universal church recognizes the hundreds of thousands of people fleeing, violence, war and poverty — Fr. Corey Brost, CSV, offers one more video that reflects on the Catholic response: advocacy.

Fr. Brost is a member of the Chicago-based Priests for Justice for Immigrants, which filmed a series of videos giving individual perspectives and testimonials. In this last video, Fr. Brost urges Catholics to advocate for asylum seekers, DACA recipients and undocumented workers trying to feed their families, and he points to St. Oscar Romero, Dorothy Day, Cesar Chavez and Joanna Williams, director of the Latino Border Initiative at the Mexican and Arizona border, as modern day examples.

“As Catholics, we need to not only serve migrants,” he says, “but advocate for them in our broken immigration system.”
