Vice President Joe Biden, speaking at the National Hispanic Prayer Breakfast Thursday, slammed Republican lawmakers opposed to the push for comprehensive immigration reform, calling the White House’s blueprint the “Christian thing to do.”

As lawmakers move closer to a compromise on border security, the free-talking Biden had some fiery words for Republicans who have accused the White House of executive overreach on immigration.

“Many of these same [GOP] representatives talk about their Christianity and their fidelity to the Bible, but they forget Matthew Chapter 25, Verse 34, where scripture teaches us: ‘I was hungry and you gave me food; I was thirsty — you gave me drink. I was a stranger, and you welcomed me,’” Biden said pointing to a Republican amendment that would have blocked President Obama’s decision to halt the deportation of so-called DREAMers.

Biden later added, “It’s the right thing to do; it’s the Christian thing to do. But it’s also an incredibly practical thing to do.”

The vice president did not specifically address an amendment being offered by Sens. John Hoeven, R-N.D., and Bob Corker, R-Tenn., which would double the number of border agents to 40,000 and call for nearly 700 miles of fencing on the U.S.-Mexico border. But generally, he recognized the GOP concerns about border security.

“Every country has a right to defend its borders and control its borders,” Biden said. “That is essential. You make no apologies for that. But it’s time we passed firm but fair reforms to bring 11 million undocumented immigrants out of the shadows.”
