Oprah Winfrey's new television show 'Greenleaf' will show the ''flawed'' side of Christianity.

The 62-year-old star says the programme - which she both acts in and produces - has been concocted to help ''raise consciousness and lift people up''.

She told PEOPLE magazine: ''Do you not think people in the church are flawed? That's why they're going ... I do everything from the point of view of intention, and the intention in all of my work is to raise consciousness and lift people up. I am not gonna do anything that is derogatory toward the church because I am of the church.

''The church is such a powerful institution in the African-American community and, I thought, a bedrock for storytelling and for sinning and for learning how to forgive and to overcome your flaws and faults and all that. So it's just a beautiful platform.''

Meanwhile, Oprah also admitted it was a ''dream'' to have a scripted show on her own network.

Speaking at the Tribeca Film Festival, she added: ''Being able to do this show is a dream come true for me. When I started this network five years ago every word that was written, the narrative for OWN was struggling, struggling, struggling network. Our team got together and had the dream of being able to do this kind of scripted television ...

''What this taught me is that dreams, as big as I can dream and as big the dream that God has held for me, things get even bigger and better.''
