With the advice and guidance of Jim Adams of The Center for Progressive Christianity in the US, Gretta Vosper founded the Canadian Centre for Progressive Christianity and has served as its Chair since its inception. Gretta’s recent book With or Without God became a national bestseller within a week of publication and has stirred controversy across the church. She has been the subject of articles in the Globe and Mail, MacLean’s Magazine, the National Post, Calgary Herald, Vancouver Sun, the Toronto Star, and The United Church Observer. Bishop John Shelby Spong, who wrote the forward for her book, introduced Gretta to his readership as a guest columnist, calling her “one of the most exciting voices in 21st century Christianity.” She ministers with the congregation of West Hill United Church in east Toronto.
