What holds the Church together when the world pulls it apart? Upon This Rock is a sweeping, honest, and accessible journey through Christian history, revealing the biblical and historical roots of the Catholic Church-and the central role of Peter and his successors in preserving unity across centuries of division. Blending thoughtful apologetics, personal insight, and deep reverence for truth, John Henry guides readers through the early Church, the great heresies, the East-West schism, the rise of Protestant denominations, and the theological confusion of modern times. Along the way, he confronts the myths, misunderstandings, and mistrust that often surround the papacy, showing how Christ's design for His Church includes a visible shepherd to guard the deposit of faith and guide the flock through every storm. Whether you're Catholic, Orthodox, Protestant, or simply curious, Upon This Rock invites you to rediscover the blueprint Christ gave us-not for chaos, but for communion.
