The Complete Marcion: A Comprehensive Examination of Marcion Sinope and His Role in Shaping Early Christianity

Around 144 AD, Marcion of Sinope was expelled from the Roman church. His writings were destroyed, his communities condemned as heretical, and his name became a byword for everything the emerging Catholic Church opposed.Yet Marcionite churches survived for centuries across the Roman Empire, from Syria to Persia. Today, scholars remain deeply divided: Did Marcion corrupt the gospel, or did he preserve an earlier, purer version than the one the church eventually canonized?The Complete Marcion brings together, for the first time in a single accessible volume, everything needed to understand this pivotal and misunderstood figure. Drawing on all seven major hostile ancient sources, Justin, Irenaeus, Tertullian, Hippolytus, Epiphanius, Adamantius, and Eusebius, plus the best modern scholarship (Lieu, Klinghardt, Vinzent, BeDuhn, Roth, Harnack), it reconstructs his life, his dualistic theology, his ascetic communities, and the lost scripture at the heart of the controversy: the first Christian canon.That canon had two halves, and this book reconstructs both. A detailed, verse-by-verse reconstruction of Marcion's Gospel is now joined by a complete, continuously readable reconstruction of his Apostolikon, the ten letters of Paul as Marcion's churches read them, with the omissions and altered readings the ancient witnesses attest marked at every seam. Together they put the entire Bible of the man the church called its first heretic into your hands, as closely as the evidence allows.Around that core, the book offers a critical reading of every hostile source and a balanced examination of the explosive priority debate: did Marcion's gospel come before Luke, or after? A closing chapter then follows Marcion's central question, what Christianity has to do with the God, the scriptures, and the people of Israel, out of the second century and into the modern world, where it took on a resonance its author never foresaw.The result lets you engage the evidence directly and decide for yourself: Was Marcion a dangerous heretic... or the man who forced Christianity to assemble its New Testament?Read the sources. Examine the reconstruction. Make up your own mind.About the AuthorBryan Manning is an independent scholar who has spent more than twenty years exploring the intersection of religion, history, and power.
