We first heard about Dr. Jerry Mungadze when he appeared on a program with televangelist Joni Lamb of Daystar dedicated to the wonders of ex-gay therapy, where he maintained that he has seen the physical “healing” of gay people’s brains as they transition from “showing the homosexuality” to “show[ing] heterosexuality.”

It later turned out that Mungadze, who is not a scientist but a “scholar” with degrees in biblical studies and counselor education, wasn’t referring to actual brain scans but to crayon drawings of brains. Mungadze claims that based on the colored pencil or crayon a person chooses to color in a picture of a brain, he can tell if they are gay or straight.

He took his “science” to televangelist Benny Hinn’s show This Is Your Day earlier this week, where he also revealed that he can tell if someone is possessed by demons if they choose darker colors on their brain map.

“Everything that I talk about is based on numbers, is based on studies, which is what you do is when you’re a scientist,” he told Hinn, adding that “you can actually see demonization in people’s brains.”

“There’s a certain color that I won’t mention that tells me if someone is demonized,” Mungadze continued, until he ultimately revealed that dark colors such as black, brown and gray are proof of demonic possession.

“I can be in a room with people who are into the occult who are steeped in demonology, I may not know it just by sitting next to them but I let them do that and I can tell what spirit they have,” Mungadze said. “People that come from the occult, people coming from witchcraft usually [choose] blacks and browns and grays.”
