We are all interested in lives of the saints – those extraordinary men and women who show the rest of us what it really means (and costs) to follow Christ all the way. I thought of them as I read and wrote about the newly canonised St John Henry Newman. This scholarly Englishman, whose collected writings fill many shelves, is very different from the American pacifist and champion of the poor, Dorothy Day, but they would have recognised each other in their devotion to the truth (they were both converts) and their determination not to compromise over the teachings of Christ.
