Marcion of Sinope (c. 100–165 CE) occupies a contested but significant position in the depth-psychology corpus, appearing primarily as a radical theological systematizer whose dualism illuminates ancient anxieties about divine justice, cosmic evil, and the nature of the creator. Hans Jonas provides the most sustained and analytically precise treatment, situating Marcion within—yet distinct from—the broader Gnostic movement: for Jonas, Marcion's innovation lies in his absolute separation of the 'just' Demiurge from the 'good' alien God, a polarity that sharpens the Pauline antithesis of law and grace into formal theological contradiction. Karen Armstrong contextualizes Marcion as a symptom of widespread dissatisfaction with the inherited Jewish God-concept, noting his appeal to converts who experienced the world as irredeemably cruel. Karen King's historiographical study uses Marcion as a boundary case for defining Gnosticism itself, stressing his literalist hermeneutic and his editorial campaign to purify Pauline Christianity of Judaizing contamination. Thielman approaches Marcion from a canonical-theological angle, treating him as a precursor to Enlightenment reductionism in gospel criticism. The cluster of concerns these authors activate—demiurge, dualism, asceticism, canon, Old Testament repudiation—makes Marcion a recurring diagnostic figure for how the Western religious imagination handles the problem of evil and the split God-image.

Jonas identifies Marcion's central theological move as the formal separation of justice and goodness into two irreconcilable divinities, dissolving the Pauline dialectical tension into stark dualism.

not to complete but to reduce the world of the creator and to make the least possible use of it. 'By way of opposition to the Demiurge, Marcion rejects the use of the things of this world'
Jonas argues that Marcion's ascetic ethics follow directly from his metaphysics: since the world belongs to the just-but-alien Demiurge, moral practice consists in minimizing one's entanglement with creation.

Marcion was also appalled by the Jewish scriptures, which seemed to describe a harsh, cruel God who exterminated whole populations in his passion for justice. He decided that it was this Jewish God, who was 'lustful for war, inconstant in his attitudes and self-contradictory,' who had created the world.
Armstrong frames Marcion's dualism as an emotional and moral reaction to Old Testament violence, positing a second, purely good God revealed by Jesus in radical contrast to the creator.

the demiurge with the Good God. The former is a divinity in his own right, expressing his nature in the visible universe his creation, and he is the anti-thesis to the Good God not as evil but as 'just.'
Jonas carefully distinguishes Marcion's Demiurge from the Gnostic Prince of Darkness: the creator is not evil but merely just, making Marcion's dualism structurally unique within the Gnostic field.

Marcion read the Jewish Scriptures almost exclusively in a literal manner. When he did, it seemed to him that these writings were the work of an inferior creator God.
King distinguishes Marcion from allegorizing contemporaries by emphasizing his literalist hermeneutic, which led him to conclude that the Hebrew scriptures revealed only a lesser deity, not the true God of Jesus.

The worst provocation came from Marcion's pitiless contempt of the creator a
Jonas notes that Marcion's anti-cosmic contempt for the Demiurge was the most extreme provocation faced by both the Church and classical philosophy in their defense of cosmic order.

Marcion claimed that the four gospels reflected the corrupt Judaizing tendencies of those who wrote them. He tried to restore the single, Pauline gospel in all its purity by radically editing Luke's gospel
Thielman situates Marcion's canonical intervention as an attempt to purify Christian scripture of Jewish contamination, making him a proto-critic of gospel plurality and a precursor of later reductionist hermeneutics.

Just as Marcion and Tatian constructed from one or more of the commonly accepted gospels a single narrative that fit their philosophical presuppositions, so the lives of Jesus that arose out of the Enlightenment and modernism often purged the gospel accounts of their miraculous element
Thielman draws a structural parallel between Marcion's editorial reduction of the gospels and Enlightenment-era historical Jesus research, both driven by prior philosophical commitments.

Harnack also believed that John, like Paul, Marcion, and Luther, had rejected Jewish legalism and emphasized freedom.
Thielman reports Harnack's controversial genealogy linking Marcion, Paul, and Luther as a continuous tradition of anti-legalist, freedom-centered Christianity.

Origen, writing in the third century, could answer Marcion's disparagement of the orthodox attachment to four different gospels with the comment that 'there is one who is preached by all'
Thielman documents the patristic response to Marcion's gospel reductionism, showing how Origen's defense of gospel unity was framed precisely against Marcion's single-gospel position.

the relation to the Pauline antithesis of law and grace will come up presently
Jonas briefly signals that the Gnostic repudiation of the Old Testament God's law connects to the broader Pauline antithesis of law and grace, a theme central to Marcion's theology.

The second view was that of the Gnostics. This, we have seen, was in its theology older than Christianity and alien to the Jews
Campbell contextualizes the theological milieu from which Marcionism emerged, contrasting the Jewish apocalyptic view with the alien-God theology that Marcion would radicalize.
