Pastor John Lowe II admitted a grave sin in an address to his church on Sunday, saying he committed adultery and asking for their forgiveness. But then things took a sudden and dramatic turn: A woman stepped forward to say Lowe had sex with her when she was only 16.

Lowe's initial remarks at New Life Christian Church and World Outreach in Warsaw, Ind., had seemed to satisfy the congregation. He received a standing ovation after he confessed, calling for privacy and healing and saying he was stepping down.

But as Lowe set the microphone down, a woman and her husband approached the stage and picked the mic back up.

'You are not the victim here,' woman tells pastor

The woman told her own story, of a teenager whom the pastor repeatedly sexually victimized, and of a sexual relationship that extended into her 20s.

"I lived in a prison of lies and shame" for 27 years, she said.

"I was just 16 when you took my virginity on your office floor," the woman told Lowe, who stood at the front of the pews.

"You are not the victim here," she said, saying he had not admitted the full truth of what he had done.

She added: "You did things to my teenage body that had never and should have never been done."

For years, the woman said, she had wanted to speak about the issue, but people were either too afraid or wanted to cover up the incident.

"This church has been built on lies, but no more," the woman said. "The lies need to stop." 

Lowe had depicted his actions as an isolated incident, and one that he repented 20 years ago. "It was nearly 20 years ago. It continued far too long," he said.

But the woman and her husband cast it in a different light.

"My wife — it's not just adultery," her husband told the congregation. "It's another level when it's a teenager. And I will not let this man talk about my wife like that. It happened for nine years. When she was 15, 16, the sexual grooming started. It lasted until she met me and we started dating. This is the truth."

She recently decided to come forward, the woman said, after her brother asked her about something he had seen as a teenager that long bothered him: the sight of "his pastor in bed with his younger sister, a T-shirt and underwear on."
