I just heard about this on NPR and I was only casually listening.
But there is a new movie on Netflix called Come Sunday which is about Carlton Pearson and his leaving a Pentecostal church. Here is an article by Ted Resnikoff
“Come Sunday, premiering on Netflix April 13, tells the story of how Bishop Carlton Pearson’s epiphany about God’s love cost him his congregation, affiliation with the Joint College of African-American Pentecostal Bishops, and a lot of money, but it only elliptically explains why he found a home for his faithful, and a place to minister and share his message of inclusion, at a Unitarian Universalist church.”
Hope you get a chance to watch it.
