Apostle for Our Time is a compelling portrait of Pope Paul VI, the transformative pontiff who steered the Catholic Church through the turbulence of the 1960s and 1970s. William J. Clancy charts Giovanni Battista Montini's journey from his early diplomatic service in Milan and the Vatican Secretariat of State to his pivotal role in validating the reforms of the Second Vatican Council (Vatican II). Clancy explores Paul VI's efforts to modernize the Church—promoting liturgical renewal, ecumenism, and engagement with global issues—while also highlighting the challenges he faced: internal criticism, geopolitical upheaval, and the lasting tensions over the document Humanae Vitae. Through interviews, archival documents, and clear narrative, Clancy presents Paul VI as a pastor navigating tradition and change. Ideal for readers interested in modern Church history, papal biography, and the legacy of Vatican II, this biography offers both historical insight and human warmth.
