Case in point: In his first pastoral visit last July, the pope journeyed to Lampedusa, a tiny island off the coast of Sicily through which more than 200,000 migrants and refugees have entered Europe since 1999. Lamenting “global indifference” to the plight of migrants and refugees, Francis threw a wreath into the Mediterranean in remembrance of those who had lost their lives there.

Such acts send a powerful signal, says Kevin Appleby, head of migration policy for the USCCB. This, in turn, inspires like-minded advocates to “lead the charge” on the issue, as when a contingent of U.S. bishops traveled to Nogales on April 1 to celebrate Mass across the U.S.-Mexican border, conduct their own wreath-laying ceremony, and, while they were at it, call on Congress to quit dorking around and do something about our nation’s dysfunctional immigration system.

Five days later came Jeb Bush’s “act of love” moment, which Carr found “stunning,” and Appleby found encouraging. “When someone like Jeb Bush comes out and makes a comment that humanizes immigrants, I think it is in part inspired by the Holy Father,” says Appleby, who has been working on this issue with the USCCB for about 15 years. “In some ways, the Holy Father is providing some cover. Not intentionally. But for those who are sympathetic to his message, he provides cover to be more courageous and to speak about the issue from the human side.”
