Ancient Heretics: Marcion

Marcion, born in Pontus (modern day Turkey) about 85 AD, was one of the more significant of the gnostic heretics. The impact of his teachings and movement are largely unknown today. However, many of his doctrines survive in modern heretical movements.


We are posting a number of e-letters Make Sure Ministries has received from David Henke, founder of Watchman Fellowship, Inc., an apologetics ministry, on a variety of subjects. They will post on Tuesdays into the foreseeable future. As always, we appreciate your comments. Please consider clicking on the link following this blog to learn more about Watchman Fellowship and what they have to offer. E-letters have been slightly edited for clarity.


Gnosticism holds that the material world is evil but the spiritual realm is holy. This led to heretical views that Jesus was not genuinely a flesh and blood man but a manifestation. You will find Gnosticism in modern cults such as Christian Science, among others.

Marcion saw himself as a reformer. According to him, the bad influence corrupting the Church and the Gospel were derived from the Jews and the Old Testament. The Encyclopedia of Religion, p. 468, says that Marcion spent much of his life in “… the attempt to purify Christianity from all contact with Judaism. His real cleavage with orthodoxy lay in his denial of unity to the First Principle [monotheism – editor]. There were two gods, a just [God] depicted in the Jewish scriptures (the demiurge or creator) and a good God revealed by Christ. The one demanded ‘an eye for an eye and a tooth for a tooth,’ the other ‘To him that smiteth on the one cheek offer also the other.’ Many skeptics today hold that Jesus is acceptable as a representation of God but the Old Testament Yahweh was a monster because He was ‘bloodthirsty.'”

This seemed a logical contradiction to Marcion, which led to his rejection of the entire Old Testament canon. Among the New Testament books, he accepted ten of Paul’s letters but edited by Marcion to exclude any Jewish elements, and a similarly revised Luke. This, Marcion presented as the acceptable content of a New Testament canon. Until then the Church empire wide received and regarded the writings of the Apostles as God-given. A formal canon had not been approved. Christians everywhere heard the Voice of their Shepherd, Jesus, and received it. “My sheep hear my voice and I know them and they follow me” (John 10:27-28). Thus, the books that later were recognized as the canon were in common use by the Church and were recognized as authoritative.

Because the Church had not yet officially recognized, or ‘canonized,’ them as the complete revelation of the New Testament gospel, Marcion had an opening for offering his views as an alternative to the common Church view. In 144 AD, he presented his views to the church in Rome. The leaders in Rome were aghast at Marcion’s heresy and excommunicated him. He returned to Pontus and continued to propagate his gnostic doctrines. Gnosticism was as prevalent in the first and second centuries as evolution is today and impacted the Church many times.

The absence of controversy in the area of doctrine can lead to an imprecise understanding of it. When controversy, or heresy, rears its head, the understanding of what the Bible teaches must be defined first before the error can be properly refuted. Most of our creeds come from such controversy. The creeds are simply precise expressions of what the Bible teaches on given topics. C.S. Lewis, in his book Mere Christianity, refers to this as the “shock of controversy” that led to the crystallization of the Trinitarian formula we know today.

Like other gnostics, Marcion affirmed the deity of Christ. However, because of their gnostic belief that matter is inherently unholy they could not accept that Christ was incarnate, having a genuinely material body. His body was a manifestation, but not real substance. Marcion affirmed this tenet as well. But, Marcion, in effect, equated Christ with the Father Whom He was revealing. This is the modalist concept of God wherein one Person is at one time the Father, another He is the Son, and at another time is the Holy Spirit. One Person, One God. This teaching is refuted by John in chapter one of his gospel and also in the benedictions, baptismal formulas and the baptism of Jesus. The Marcionites, interestingly, practiced baptism for the dead, as did the Montanists.

There are mysteries and paradoxes in Scripture that give rise to differing views on how they are resolved. Martin Luther thought the Epistle of James should not have been in the canon because it seems to support works for salvation. Some of the early Church Fathers differed on what books should be considered as divine revelation because they perceived conflicts in them with other accepted revelation. Tertullian thought the Book of Enoch should be in the canon but finally accepted that God did not move the Church to accept it. As time went on these differences were resolved. The tension arising out of these perceived conflicts have led to numerous heresies, sects, denominations, theological schools of thought, etc.

The multitude of differences among us is in stark contrast to the rock-solid unity of Scripture and its universal acceptance. This reality is a commentary on the readers of Scripture, not on the Scripture itself. Our knowledge and perspective are limited. Humility is therefore in order.
