Early Christianity: From Christ to Constantine traces the astonishing rise of the Christian faith from its roots in first-century Judea to its endurance under the Roman Empire’s fiercest persecutions. Anchored in Scripture and guided by a rigorous historical-grammatical method, this book unfolds the dramatic story of how the gospel was proclaimed, defended, preserved, and lived out by ordinary believers and courageous leaders across three centuries. Far from a dry chronicle, this narrative immerses readers in the world of Jesus and the apostles, follows the spread of the good news throughout the Mediterranean, and examines the challenges that confronted the growing congregations—false teaching, internal conflict, moral pressure, and the deadly hostility of imperial power. Yet through every trial, the early Christians displayed unwavering devotion to Christ, confidence in the authority of the inspired Word, and steadfast hope in the promise of His return. From the ministry of the apostles to the emergence of teachers, apologists, and martyrs, from doctrinal clarity to the preservation of Scripture and the shaping of Christian identity, this volume brings to life the faith, courage, and endurance that marked the church’s first generations. It shows how Jehovah worked through imperfect but faithful men and women to guard the truth, spread the gospel, and establish congregations that would outlast every earthly empire. Both deeply researched and spiritually grounded, Early Christianity: From Christ to Constantine offers a clear and compelling account of how the church was built—not by political power or human ingenuity, but through the risen Christ who continues to keep His promise: “I will build my church.”
