The Rise of Marcion and the Fall of the Faithful uncovers one of the most damaging moments in early Christian history. Marcion of Sinope stepped into the second century convinced he had discovered a "better gospel," one free from the God of Israel, the Hebrew Scriptures, and the covenant story that shaped the apostles. His teachings spread fast and loud, pulling entire communities away from the faith once delivered to the saints. Many modern Christians know little about him, yet his fingerprints remain everywhere in today's doctrine, church culture, and attitudes toward the Old Testament.

This book walks you through the life, influence, and long shadow of Marcion. You see how his ideas challenged the early believers, how leaders like Irenaeus and Tertullian answered him, and why the conflict still matters today. You learn how Marcion reshaped the conversation about Scripture, canon, grace, law, and the identity of the God of the Bible. You also see how his errors re-emerged through later movements, from Gnosticism to modern forms of antinomianism, replacement theology, and the common belief that the "Old Testament God" is somehow different from the Father revealed by Yeshua.

The book doesn't stay in the past. It shows how Marcion's thinking operates in sermons, seminaries, and social media debates right now. You discover why the early church fought him with such urgency and what his rise teaches you about staying rooted in the full story of Scripture. You watch how the faithful defended the continuity of Genesis through Revelation, and how their stand protects your understanding of the gospel today.

If you want a clear look at the first major heresy to confront the church, if you want to understand how early believers guarded the faith, and if you want to see why loving the God of Israel matters for every follower of Messiah, this book gives you the trail, the evidence, and the clarity you need.
