Catholics and Co-ops This film explores the Roman Catholic affinity for the co-operative enterprise as an expression of Catholic Social Teaching. We examine the impact of three important Encyclicals on five remarkable priests and one Congregation of Women Religious as they established worker co-ops, credit unions and housing co-operatives in Canada and Spain. From Rerum Novarum in 1891 to Laudato Si’ in 2015, Catholic Social Teaching has influenced Catholic men and women, lay and religious, to establish democratic co-operative enterprises. And the inspiration comes from their faith. This is their story.
