Mary Cosby has faced relentless scrutiny ever since she joined the Bravo reality show, The Real Housewives of Salt Lake City, thanks to her highly controversial marriage to her step-grandfather and her questionable involvement with the Faith Temple Pentecostal Church. After years of whispers surrounding the reality star’s “cult-like” leadership behaviour in the church, a new TLC docuseries has amplified the accusations, as ex-congregants and family members shared their experiences.
Titled The Cult of the Real Housewife, the 2026 exposé unpacks explosive claims surrounding Mary’s involvement with the church in Salt Lake City, a congregation founded by her grandmother, Dr. Rosemary “Mama” Redmon Cosby, in the 1960s. After her grandmother’s death, Mary took on the role of first lady of the church and has since been accused by former members of running it like a cult and living off the money donated by parishioners.
What are the cult allegations, and where did they come from?
