This year marks the 50th anniversary of the publication of a very significant book, We Hold These Truths: Catholic Reflections on the American Proposition, by Father John Courtney Murray, S.J. It is significant not only for what he said but for when he said it. He wrote just before the Second Vatican Council took place. In fact, he was an expert who was called on at that council for his theological expertise, particularly in the area of the relationship between church and state.
