Carrie Underwood is being characterized as unchristian for her recent endorsement of equal marriage rights for gay and lesbian couples.

The 29-year-old Underwood has gone on to stardom after winning American Idol in 2005. Her debut album, Some Hearts, included the hit single Jesus, Take the Wheel.

In an op-ed, World Net Daily founder Joseph Farah suggested the country music star heed her own advice and let “Jesus take the wheel.”

Farah, an opponent of gay rights, knocked Underwood for saying that “God wanted us to love others” and “It's not up to me to judge anybody” in offering her support for gay nuptials.

“You can't be a follower of Jesus and condone what He Himself describes as sin,” Farah wrote. “Neither can you truly love others by purposely not confronting their sin – and allowing them to be comfortable with their sin.”

“She says, 'It's not up to me to judge anybody.' This has become something of a mantra in the apostate church. But it is a misunderstanding of what Jesus meant when He said, 'Judge not, that ye be not judged.' The context of that sermon makes it clear that Jesus meant to do unto others as you would have them do unto you. Others are not to be judged unfairly. He didn't mean we aren't supposed to confront people with their sin so they could be brought to repentance, because He Himself commanded us to do just that.”

“God did warn us not to profane His holy name.”

“I don't think that just means misusing His name as a curse word. I think we do that when we represent ourselves as followers of God but betray His Word.”

“That's blasphemy – and there's just too much of it coming from people claiming to be Christians.”
