Father Louis Bouyer, C.O., is one of my favorite theologians, so I am happy that Ignatius Press has republished his little classic, The Word, Church and Sacraments in Protestantism and Catholicism. A former Lutheran pastor, Fr. Bouyer (b. 1913) entered the Catholic Church in 1939 and was ordained to the priesthood in 1944. He taught at the Institut Catholique in Paris, lectured at Notre Dame and Loyola University, and wrote numerous books. He was a theological expert at the Second Vatican Council.
Here's a description of The Word, Church and Sacraments in Protestantism and Catholicism, published in French in 1960:
The Word, Church and Sacraments in Protestantism and Catholicism is a theological classic. It seeks to foster unity and deeper understanding among Christians by comparing the Catholic and Protestant views of Scripture, Church authority, and the Sacraments. Bouyer, one of the greatest theologians of the 20th century and a convert from Protestantism, contributed significantly to the movement out of which came the Second Vatican Council's efforts to promote Christian unity. In The Word, Church and Sacraments, he shows how Catholic teaching is often misunderstood by Catholics and Protestants alike, and how this teaching is fundamentally compatible with key positive elements of Reformation thought. He also examines the main points of disagreement between Catholicism and Protestantism, and demonstrates how Catholicism, properly understood, maintains the theological balance necessary to uphold some of the main truths on which Catholics and Protestants agree.
