Former Republican presidential hopeful Mitt Romney lashed out at the decision to have a controversial evangelical leader give a blessing at the opening of the U.S. Embassy in Jerusalem Monday, calling him a “religious bigot.”

The Senate candidate from Utah criticized the inclusion of the Rev. Robert Jeffress — the pastor of First Baptist Church in Dallas who is also an an adviser to President Donald Trump. The president recognized Jerusalem as Israel's capital last year.

“Robert Jeffress says, ‘You can’t be saved by being a Jew,’ and ‘Mormonism is a heresy from the pit of hell,’” Romney wrote in a tweet Sunday night. “He’s said the same about Islam. Such a religious bigot should not be giving the prayer that opens the United States Embassy in Jerusalem.”

Romney is Mormon.

Jeffress denied he was a bigot, but added that he believed Mormonism was “wrong,” and said the Southern Baptist Convention had designated it a “cult.”

“Mormonism has never been considered a part of historic Christianity. People may disagree with that view, but it’s not a view unique to me,” he said in an interview with NBC News.

Along with many other evangelical so-called Christian Zionists, Jeffress is a strong supporter of Israel and the decision to move the U.S. Embassy to Jerusalem — a move condemned by Palestinians and many foreign governments.

Jeffress bases his beliefs and his general opposition to a two-state solution to the conflict between Israel and the Palestinians on his strict interpretation of the Bible.

“The Bible says this land belongs to the Jewish people — period,” he told NBC News in a separate interview in February. "God has pronounced judgment after judgment in the Old Testament to those who would ‘divide the land,’ end quote, and hand it over to non-Jews.”
