A theater buff loved the “The Book of Mormon” so much, she converted to the religion.

Liza Morong, 21, of Boston, said she knew the edgy musical was a spoof on the faith when she saw it on Broadway — but it sparked her curiosity and ultimately changed her life.

“I laughed hysterically the entire show. I thought, wow, these people are crazy. They must be brainwashed,” Morong told the Deseret News of Salt Lake City.

“[But] my life has changed. I am so much happier,” she said.

Morong logged onto the church Web site Mormon.org after seeing the play — written by the creators of “South Park” — in September 2011.

The college theater major claims she simply wanted to learn more about a faith she considered wacky — and maybe even have a laugh.

A missionary from the Web site then contacted her, requesting to chat online, and she agreed.

“I thought, these clowns are in for a treat with me,” Morong said.

But Morong — who grew up Congregationalist — began chatting with the missionary via Facebook. His kindness was disarming, she said. She soon met the missionary, Elder Trevor Boardman, in person to read from the real Book of Mormon.

This time, she wasn’t laughing.

Morong said Boardman, who has muscular dystrophy, helped her feel closer to God.

That’s when she had an epiphany, she said.

“I was riding my bike to class one morning . . . I remember the light was just passing through the branches of the trees,” she said.

“I felt this peace that I have never felt before. I thought to myself, that just came from God.”

Friends at a church group convinced her to undergo a baptism.

In December 2011 — four months after seeing “The Book of Mormon” at the Eugene O’Neill Theatre — Morong stood in waist-high water wearing all-white garb for the ceremony in Mapleton, Utah.

She now considers herself a devout member of the church — and she credits the theater production for sending her down the unusual spiritual path.

“Because of this musical, a beautiful chapter in my life started and continues to grow,” Morong wrote on her blog.

She conceded that not everybody in the church likes the message of the show, which spoofs too-literal religious beliefs as it follows two Mormon missionaries who try to convert Ugandan natives.

“Although several members of the church are offended by this show,” she wrote, “it changed my life.”
