For decades, a little-known Christian sect has dealt with its abusive ministers and spiritual elders mostly in secret, shunning legal action in favor of urging victims to forgive the predators in their midst. Now a grassroots effort by survivors has exposed the depth of the scandal — documenting allegations against more than 900 abusers in 30 countries, with cases continuing to emerge — and thrust the nameless sect into the public eye. The Associated Press interviewed more than a dozen current and former members, workers and experts, and reviewed letters, court documents and other records supporting the allegations.
