People of God is a brand new series of inspiring biographies for the general reader. Each volume offers a compelling and honest narrative of the life of an important twentieth or twenty-first century Catholic. Some living and some now deceased, each of these women and men have known challenges and weaknesses familiar to most of us, but responded to them in ways that call us to our own forms of heroism. Each offers a credible and concrete witness of faith, hope, and love to people of our own day. The canonization of Pope John XXIII and the fiftieth anniversary of Vatican II call for a fresh look at this remarkable man. Now highly regarded Vatican II historian Massimo Faggioli offers a rich and insightful portrait. His sources include the complete edition of the private diaries of the future John XXIII, published recently in ten volumes, much of which is unavailable in English. Faggioli's use of this treasure of personal notes of the future pope means this biography offers a more complete and nuanced understanding of Angelo Roncalli than is available anywhere else in English at this time. The result is both unforgettable and inspiring.
