Actor Brad Pitt, an outspoken supporter of gay marriage, says he grew up in a Christian family which believes gay men and lesbian could not reach heaven.

The 48-year-old Pitt made his comments in an interview with People magazine to promote Killing Them Softly, his upcoming crime-thriller film.

“I come from a Christian family, and [gay marriage] goes against Christian beliefs, as far as what's going to get you into heaven or not,” he said. “My argument is, that you may be as you believe, and it may be true in the end – I don't think so – but let your god make that call, and in the meantime we live in a country where everyone should be treated equally, so let's treat everyone equally.”

The actor's positions are a sharp contrast to those of his mother, Jane Pitt.

Jane Pitt criticized President Barack Obama's support for marriage equality in announcing her support for his GOP rival, Mitt Romney.

“I think any Christian should spend much time in prayer before refusing to vote for a family man with high morals, business experience, who is against abortion, and shares Christian conviction concerning homosexuality just because he is a Mormon,” she wrote, referring to Romney.

“Any Christian who does not vote or writes in a name is casting a vote for Romney's opponent, Barack Hussein Obama – a man who sat in Jeremiah Wright's church for years, did not hold a public ceremony to mark the National Day of Prayer, and is a liberal who supports the killing of unborn babies and same-sex marriage.”
