The Rev. Robert H. Schuller's granddaughter recently penned a book about women and Christianity titled “God and Boobs, Balancing Faith and Sexuality.”

SANTA ANA, Calif. — Angie Schuller Wyatt has a famous name.

“My grandpa is that preacher guy,” she tells Twitter followers.

So, earlier this year, as she geared to release a new book about women and Christianity, it seemed like a no-brainer that the oldest granddaughter of the Rev. Robert H. Schuller would promote it on the international “Hour of Power” television show at the Crystal Cathedral, the ministry her grandfather built so many years ago.

There were some negotiations, like don’t mention the book title. But the deal was set.

Then, about a month before the scheduled show, she got a brief e-mail from cathedral staff. The interview was off. There was no specific reason given, just a generic not-in-the-best-interest-of-the-cathedral line.

But perhaps the book’s title (“God and Boobs, Balancing Faith and Sexuality”) and its outspoken author were a little too much for a church undergoing sweeping change. Even the picture on the book’s back cover — a woman wearing only a black-laced pink panty — might’ve been a problem.

Schuller Wyatt, 35, is not afraid to rankle the Christian establishment. Nor does she shy away from voicing opinions on her family or the downfall of the once prominent Crystal Cathedral Ministries, which on Sunday left its glass-covered church for a humbler abode following bankruptcy and controversies.

A writer, counselor and pastor, Schuller Wyatt said she has broken away from religious constraints and embraced her sexuality. Her goal is to help other women do the same — have a relationship with God even as they maintain their femininity.

“My mission is to reach women who are on the fringe of the faith,” she said. “I stood at one of the world’s most prominent religious altars and felt as an outcast. So how must women feel who stand at the outskirts of faith?

“I have not been interested in pleasing religious people.”

The childhood memories are fun. PKs — or preacher kids — grew up running around the tunnel-like passageways in the cathedral’s vast basement, which houses the studio and offices where the “Hour of Power” is produced.

Growing up a Schuller was different.

Her grandfather was famous. So was her dad, Robert A. Schuller, the ministry’s heir apparent. Wherever she went with them they were stopped for a blessing, a prayer, an autograph.

“My grandfather and dad were celebrities,” Schuller Wyatt said. “It was an interesting dynamic to grow up having faith and fame and family all so intricately connected. It was fun. And it was exciting to feel proud of my grandfather for doing something so important for the world.”

Still, Schuller Wyatt said she didn’t fit in. A boys’ club, she called it. “Though heir to this masculine dynasty, I’m of another fabric,” she writes in her self-published book. “Not only do I have a different first name, I also have boobs.”

Her father, her aunts and their spouses, and other family members all had paid jobs in the church. Schuller Wyatt did not.

“Rather than get involved in the family tangle, I said ‘I’m going to leave, build my career — and figure out who I am.’”
