This book brings together theologians and pastors from two Christian traditions in Ireland - Catholicism and Presbyterianism - to explore the legacy of two significant figures, John Calvin and Ignatius Loyola. The papers in this collection from a conference held at St. Patrick's College, Maynooth, put into relief the important values they held in common - a profound faith in Christ, a dedication to the people in their community of the Church, and their missions as they understood them.
