One of the most theologically fascinating and entertaining books I’ve read in a long time is Yves Congar’s My Journal of the Council.
Most Catholics under age 50 might be unaware of the massive contribution made by Congar, a Dominican priest and one of the most important Catholic theologians of the 20th century.
After a tumultuous intellectual career, Congar found himself, at age 58, a peritus or theological expert at the Second Vatican Council. By most accounts, he proved the most influential theologian at that epic gathering, contributing to the documents on the Church, on ecumenism, on revelation, and on the Church’s relation to the modern world.
