Faith that Transforms: Essays in Honor of Gregory Baum edited by Mary Jo Leddy and Mary Ann Hinsdale, is a festschrift—a collection of academic essays written by colleagues, students, and peers to honor the Canadian theologian, priest, and social activist Gregory Baum. The book highlights Baum’s significant contributions to theology, particularly his shift towards a critical theology that bridges faith with social justice and liberation, and serves as an appreciation of his sunny generosity and his ability to combine profound theological critique with a hopeful, charitable outlook.
