Franklin Graham, a leading evangelical figure, on Sunday reiterated his belief that gay sex is sin.

In an NBC Meet the Press profile, Graham, the son of evangelist Billy Graham, was asked whether he agrees with Pope Francis, who famously told reporters, “If a person is gay and seeks God and has goodwill, who am I to judge them?”

“Would there be a shift for you?” he was asked.

“God would have to shift – and God doesn't,” Graham answered. “God's word is the same yesterday and today and a million years from now, that it's sin. To tell somebody that it's okay, I know the consequences of what will happen one day when they have to stand before God. I want to warn people, and I think the pope is right when he says he is not the judge. He is not the judge. God is the judge.”

Graham added that his 95-year-old father was “very weak.”
