A former mafia enforcer turned christian pastor who impregnated and married a teenage girl with the approval of his wife thinks it's wrong his marriage is not recognised by the state, but homosexual marriages are.

Thom Miller, 60, married his 19-year-old girlfriend Reba Kerfootruba with the full support of his 44-year-old wife Belinda Miller who all live together in a small home in Ohio.

Each wife spends three nights with Miller on rotation in their Mansfield house. They are currently building a bigger home.

The pastor from Mansfield in Ohio - who was reportedly in prison for seven years and released in 1991 after stabbing a man in a bar fight - met his first wife eight years ago and they discussed polygamy but didn't try it until finally agreeing on Reba Kerfootruba.

“I don’t preach about polygamy but I feel it is a very Christian lifestyle,” Thom told Barcroft TV.

“I have no problem with homosexuals but I think it’s wrong that their marriage is now recognised by the state, but my second marriage is not."

Reverend Miller says he is the only person in their relationship allowed to have more than one partner and both wives claim to be happy.

Miller's wife Belinda made the suggestion to bring another woman into the family and claims her husband's adultery benefits both the of them.
