The new biography of venerable Isidoro Zorzano adds a relatively unknown name to the landscape of exceptionally holy men and women of the Twentieth Century. Like many of his contemporaries, Zorzano left a lasting imprint and solid example of how to uniquely live out the call to holiness in a turbulent modern world. As a young Spanish engineer and good friend of Fr. Josemaría Escrivá, Zorzano became a founding member of Opus Dei in Spain. Despite the fatal diagnosis of Hodgkin’s lymphoma at age thirty-eight, he “was content to keep working and offer everything to God,” never resting despite his quick deterioration. As a witness of silent devotion to the Lord through a life of simplicity, fidelity, and attentiveness, he became a model of attainable sanctity for both his contemporaries and future generations alike.
