PHOENIX -- A Valley landmark is at the center of a custody dispute, pitting a televangelist against a former NFL star.

At stake is a $20 million piece of property at the corner of Tatum and Shea boulevards in Phoenix.

Was the Capstone Cathedral stolen or handed over under orders from God?

Curtis Frisby is the son of the late Rev. Neal Frisby, the man who built the Capstone Cathedral nearly 40 years ago.

"The Lord told him, 'I want you to build your headquarters here,'" Frisby said.

In its heyday, the church had 4,000 members who listened to Neal Frisby preach his prophesies. Some came true, like the election of Ronald Reagan. Others, like the end of the world, did not.

It is undisputed that on his deathbed in 2005, Neal Frisby signed over the church and property to a man he'd just met, former Green Bay Packer Robert Brooks.

With that, the Frisby family was effectively shut out of the church Neal Frisby built.

When asked if he regretted introducing Brooks to his father, Frisby said, "I don't regret it…completely."

Frisby said his father only intended to allow Brooks to use the church for Brooks' own start-up ministry, but as a result of that deathbed meeting, Brooks now has the title to a piece of property worth an estimated $20 million.

"I think Neal Frisby would, as people use the phrase, turn over in his grave if he knew what was going on," said the Rev. Leroy Jenkins, Neal Frisby's former associate.

Jenkins, a famous televangelist, came to Phoenix 10 years ago to take over the Frisby ministry.

Now, he's out, too, and he's angry at Brooks.

"Yes, I think he took advantage. Big time," Jenkins said.

5 Investigates went to the church to ask Brooks for his side of the story.

After some initial apprehension, he agreed to an interview.

"They may call you a con artist," said 5 Investigates reporter Morgan Loew. "Did you con your way into this?"

"You look at the documents. The documents are public record," said Brooks. "Every board member signed off on the documents. Come on, how do you con that?"

Brooks said he had a vision from God that he would lead a congregation at the church, and he contends the dying Neal Frisby had a similar vision.

"It turned out to be a very fortunate situation for myself and our ministry, which, hopefully, will do some great things in the community, which is what I think Neal Frisby himself wanted," Brooks said.

Brooks closed the church after Neal Frisby died.

He says he's renovating it, but Frisby says he's losing patience watching a house of worship his family built sitting idle for almost two years.

"It's not being used for what it's supposed to be used, and I will say this: freely, he received it. Cost him nothing. Just handed to him. And if you can't do nothing back with it, freely received it, freely give it back," Frisby said.

One lawsuit over the ownership of the property was already settled, but Jenkins said he's thinking about filing a new lawsuit challenging Brooks.

In the meantime, Brooks said he hopes to reopen the church's doors within a few months.
