About this book

What if the sharpest challenge to a sacred text survives only in the words of its opponents?

In Antitheses of Marcion, a Christian teacher places passages from the Jewish scriptures beside the words and acts of Jesus. Marcion of Sinope argues that their contrasts point to two different gods: a just Creator and a loving Father revealed by Christ. His claim challenges the place of Jewish scripture in Christian life.

The complete work no longer survives. This account follows what scholars reconstruct from quotations preserved by Marcion’s opponents, especially Tertullian in Against Marcion. It traces the contrasts, the shorter collection of scriptures, and the communities shaped by his teaching. Throughout, the evidence asks for care: the voices preserving his words also seek to refute them.

What you’ll discover

  • A lost book’s traces Explore how hostile witnesses preserve fragments of a work their churches reject.
  • Two visions of divinity Follow Marcion’s argument that the Creator’s justice differs from the Father’s goodness.
  • Scripture set beside scripture See how opposing passages become the building blocks of Marcion’s religious challenge.
  • A shorter sacred collection Examine the place of a shortened Gospel and Paul’s letters in Marcion’s teaching.
  • Churches draw their boundaries Discover why this dispute presses other church leaders to clarify which writings they accept.

Is it for you?

This is for readers curious about how the Christian Bible took shape, and about the sharpest challenge its early shapers faced. It suits students of church history. It may suit you less if you want a complete text to read directly, because none survives.

Antitheses of Marcion by Marcion, the cover

From the 15-minute summary · Key idea 1 of 6

A lost book known through its enemies

The Antitheses was Marcion's main written work, and it served as a kind of founding charter for the churches that followed him. It never passed into the safe keeping of later copyists, since the larger churches did not preserve the writings of a teacher they had rejected. What remains are quotations, paraphrases and arguments recorded by opponents. Tertullian, writing in Latin in the early third century, is the fullest source. Irenaeus, Epiphanius and the author of a dialogue called Adamantius add more.
