World's Greatest Secret How the Greatest Teaching of Jesus was Preserved by John M. Haffert

Discover the profound truth Jesus taught that shaped early Christianity—now revealed through ancient catacomb evidence and apostolic tradition. In *The World's Greatest Secret*, John M. Haffert explores the "hard saying" that challenged even Christ's closest followers, yet became the cornerstone of the earliest Christian liturgy and the Real Presence in the Eucharist. This essential Catholic book addresses the theological mystery that divided believers then and divides them now. When Jesus first proclaimed this teaching, crowds abandoned Him—yet Peter remained faithful: "To whom shall we go, Lord? You alone have the words of eternal life." Haffert masterfully bridges ancient Christian history, scriptural truth, and modern faith crisis, proving why understanding this secret is vital for authentic Christian unity and renewal. Endorsed by St. Padre Pio and prophesied to reach its greatest impact after the author's death, this 2019 revised edition arrives at a critical moment when many Catholics question the Real Presence itself. Perfect for serious students of faith, parish study groups, and anyone seeking to deepen their understanding of Catholic doctrine and the Eucharistic mystery. 194 pages | 5.5 x 8.5 inches | World Apostolate of Fatima USA/Blue Army Press
