Dr. Franklin Graham, the son of evangelist Billy Graham, on Tuesday endorsed a proposed gay marriage ban in North Carolina.

Voters on May 8 will decide the fate of Amendment One, the constitutional amendment which would bar the state from recognizing the relationships of gay and lesbian couples with marriage, civil unions and possibly domestic partnerships.

In his recorded statement released Tuesday by Vote for Marriage North Carolina, Graham calls the upcoming vote “very crucial.”

“On May 8 we have a very crucial vote here in North Carolina and we have an opportunity to vote for the marriage amendment,” the 59-year-old evangelist said “This amendment affects all of us and that's how we define marriage in this state. And I want you to take a stand for God's definition of marriage. And that's between a man and a woman. This is very critical. This is going to affect our state for years to come.”

“So, please vote May 8. Support the marriage amendment,” he added. (The video is embedded in the right panel of this page. Visit our video library for more videos.)
