MINNEAPOLIS (WCCO) — There are many questions surrounding Prince’s untimely death, but we do know the singer was having health issues in recent weeks.

Many are wondering if his religion played a role in his choosing to receive treatment.

While the mega-pop star was known for his suggestive performances on stage, he was best known at his church for singing religious songs.

CNN was welcomed into the Jehovah’s Witness Kingdom Hall in St. Louis Park. After the musician was baptized in 2003, the place of worship was Prince’s home church for the past decade.

There, he went by the name Brother Nelson. Nelson is his legal last name.

The elders say he dutifully knocked on doors monthly.

“Oh, he would go door to door,” said James Lundstrom, a Jehovah’s Witness.

Lundstrom recalled a story about Brother Nelson going door to door. A woman asked him if anyone ever mentioned that he looked like Prince.

“He looks at her and says, ‘It’s been said,'” Lindstrom said. “‘Going back to my ministry here.'”

Church members say Prince looked healthy when he attended services last month.

He reportedly suffered from hip problems that required surgery.

Jehovah’s Witnesses are forbidden to receive blood transfusions, but members say that belief had nothing to do with his untimely death.

“Nobody said he couldn’t get surgery. Absolutely not,” Lundstrom said. “We’re not anti-medicine. In fact, we go out of our way to try and find the best medical care we can.”

Charity work is also a big component of the Jehovah’s Witness faith.
