Fr. Jim Gardner, SA and his presence at an ecumenical prayer service for the intention of Christian unity were recently covered in an article on Crux. In it, he gives several thoughts and teachings on the cause for Christian unity, and the history of Interdenominational relations is addressed as well.
“Gardiner gave a quick overview of the many church documents on ecumenism and interfaith relations, including the Second Vatican Council’s Decree on Ecumenism (“Unitatis Redintegratio”), which said that ecumenism should be everyone’s concern and that genuine ecumenism involves a continual personal and institutional renewal.”
