WATCH: Leah Remini's New Scientology Doc Accuses Church of Lies, Abuse and Sexual Misconduct

"My whole life I was a very dedicated Scientologist. I didn't want to find out what I'd done was a lie," Remini says in the clip

Leah Remini is not holding back in her new Scientology documentary series.

In the A&E docuseries’ first trailer, which is hosted by the former King of Queens actress and longtime Scientology member, the church is accused of lies, abuse and sexual misconduct.

“My whole life I was a very dedicated Scientologist. I didn’t want to find out what I’d done was a lie,” Remini, who left the church in 2013, says in the Entertainment Tonight trailer. “Something inside of me was saying, ‘Get them out of this thing.’ ”

Remini, her sister and mother were members of the New York and Florida branches before they relocated to Los Angeles and joined the Hollywood Scientology center when the actress was a teen, but they all have since abandoned the church.

“Fight for your family, fight for your daughters, your sons. Let’s get to the abuses, let’s get to the abortions,” Remini, 46, continues in the video. “Wake up.”

In a statement to PEOPLE, the Church of Scientology said, “As we said before, desperate for attention with an acting career stuck in a nearly decade-long tailspin, Leah Remini needs to move on with her life. Instead, she seeks publicity by maliciously spreading lies about the Church using the same handful of bitter zealots who were kicked out years ago for chronic dishonesty and corruption and whose false claims the Church refuted years ago, including through judicial decisions. Please see our full statement at www.scientologynews.org/leah-remini.”

Remini, who is executive producing the eight-part series, also speaks with former Scientology members about their experiences within the church. “I was 14 when I started in Scientology. I had a boss who was 35 years old and we had sex and the organization did not tell my mother, did not tell the police. They’re going to sweep it under the carpet and it’ll all be over with,” a former female church member recounts in the clip.

Since leaving the church three years ago, Remini has been open about her past experiences with the religious organization, including claims she previously made about Scientology officials being controlling and intimidating toward members.

She told PEOPLE in her November 2015 cover interview of leaving the church, “I’ve been given a second chance at life and so has my family” and added “It’s like a rebirth.”

In September, she named her daughter as one of the reasons she left the church. “In my house, it’s family first – but I was spending most of my time at the church,” Remini said. “So, I was saying ‘family first,’ but I wasn’t showing that. I didn’t like the message that sent my daughter.”
