Sen. Marco Rubio fired back at CNN host Chris Cuomo after he mocked Rubio’s faith, referring to him as “Mr. Bible Boy” and joking that “he’s got a Bible quote for every moment. He just never speaks truth to power or acts on any of it.”

“The verses I tweet are usually the ones chosen by the Catholic Church for that days mass,” Rubio fired back on Twitter. “But the fact he thinks words written thousands of years ago are relevant to current events proves the Bible isn’t just a book, it’s the word of God.”
