This book illustrates the richness of the Catholic priesthood by reference to the lives of ten men who, at different stages in history, committed themselves fully to follow Christ as laborers in His vineyard. These men - St. John Chrysostom, St. John Fisher, St. Oliver Plunkett, the Cure of Ars, Cardinal Newman, Archbishop John Baptist Lamy, St. Pius X, Blessed Cardinal Clement von Galen, St. Josemaria Escriva, Pope John Paul II - although very contrasting in personality and following very different paths, have several elements in common arising from the holiness of their lives. Thus we find in all a deep personal love for Christ, a willingness to sacrifice themselves generously for the salvation of souls, a great loyalty to the Magisterium, and a rich human sensibility.
