Marcionite teaching is often summarized in a single contrast: the Father is good, while the Creator is just. The first statement comes directly from the Evangelion. The second does not. The True Testament reserves goodness for the Father, calls the Law holy and its commandment just and good, but never calls the Creator himself just. The title comes from ancient reports about Cerdo and Marcion. Adolf von Harnack did not invent it, but he defended it and placed it within a Pauline-Lutheran contrast between Law and grace. This distinction matters: a commandment can be just without its giver being identified as the Just God. The True Testament presents the Creator through his rule over the present aeon, his Law, and an administration that kills, condemns, and blinds. Our own writing has sometimes compressed that evidence into the formula “the Creator is just.” That wording now needs to be corrected.
The Formula We Inherited
We have often described Marcionite theology this way:
The Creator is just but limited. The Father is wholly good.
That formula appears throughout modern writing on Marcion. We have also repeated versions of it in our own books, sermons, commentary, courses, and website.
We have written of “the Father’s grace and the Creator’s justice.” We have said that “the Creator’s justice operates on quotas and ledgers.” We have described the Creator as “just but limited.” In Christ Without Bloodline, we referred to “the just creator proclaimed in the law and prophets.”
Those statements did not come out of nowhere. They reflect a genuine ancient tradition about Marcion. But they compress several different claims into one sentence:
- The Evangelion reserves goodness for the Father.
- The Law operates through commandment, judgment, and consequence.
- Ancient opponents report that Cerdo and Marcion distinguished the good God from the righteous or judicial God.
- Harnack defended “righteous” as a serious description of Marcion’s Creator.
- Our own writing sometimes treated that reported description as though it were a statement of the True Testament itself.
The last step is the problem.
What the True Testament Actually Says
The clearest statement is Evangelion 12:2:
“Don’t call me good. Only one is good: the Father.”
The text does not say:
The Father is good, but the Creator is just.
It reserves goodness for the Father. The Creator is excluded from that designation because the Creator is not the Father. But the verse does not supply “just” as the Creator’s corresponding title.
The same distinction appears where Christ answers the Law’s measure with the Father’s character:
“But I say to you who are listening: love your enemies. Do good to those who hate you.”
—Evangelion 3:29
The Law measures injury and prescribes an equivalent response. Christ commands love toward the person who caused the injury. He then identifies the source of this new ethic:
“Be compassionate, just as your Father has shown you compassion.”
—Evangelion 3:36
The contrast is between proportional retribution and the Father’s compassion. It supports describing the Creator’s order as judicial or retributive. It does not give the Creator “Just” as a divine title. Where our text does use the word of a divine act, “For it is just for the Lord to repay affliction to those who afflict you” (2 Thessalonians 1:3 TT), the next verse names the Lord Jesus, so that verse does not give the title to the Creator either.
The Complication in Romans
The True Testament does use the words just and good for the commandment:
“So then, the Law is holy, and the commandment holy and just and good.”
—Romans 7:7 TT, corresponding to Romans 7:12
This verse must stay central to the investigation. It keeps us from replacing one oversimplification with another.
Paul does not say that the Law is simply evil. He calls it holy, and he calls the commandment just and good. Yet he immediately explains that something good became an instrument through which sin worked death:
“Was then that which is good made death to me? May it never be! But sin, that it might appear as sin, worked death in me through the good.”
—Romans 7:8 TT, corresponding to Romans 7:13
Paul can therefore call the commandment just and good without calling the Creator just and good. The grammatical subject is the commandment, not the Creator.
That distinction is essential. A law may contain just commands while remaining unable to rescue the people it governs. Paul says precisely that:
“For what the Law could not do, weak through the flesh, the Father sent his own Son.”
—Romans 8:3
The Law commands, identifies transgression, and produces judgment. It cannot accomplish the Father’s rescue.
The Administration of Death
Second Corinthians describes the Law by its effect:
“The letter kills but the Spirit makes alive.”
—2 Corinthians 3:2 TT, corresponding to 2 Corinthians 3:6
Paul then calls the engraved code a “ministry of death” and a “ministry of condemnation”:
“But if the ministry of death, in letters engraved on stones, came with glory...”
—2 Corinthians 3:3 TT, corresponding to 2 Corinthians 3:7
“For if the ministry of condemnation had glory, much more does the ministry of righteousness overflow in glory.”
—2 Corinthians 3:5 TT, corresponding to 2 Corinthians 3:9
Paul does not deny that the old administration had glory. He says its glory fades. He does not deny that the commandment is just. He says its administration kills and condemns.
This is more exact than saying merely, “The Creator is just.” The True Testament presents an order that can issue just commands and still be unable to give life.
The God of This Aeon
The True Testament gives the ruling power of the present order another description:
“The god of this aeon has blinded the minds of the untrusting, so that the light of the Evangelion of the glory of Christ, who is the image of God, might not shine to them.”
—2 Corinthians 4:1 TT, corresponding to 2 Corinthians 4:4
The True Testament identifies this god of the present aeon with the Creator. His activity in this passage is blinding, not impartial judgment.
Galatians calls the same aeon evil and says Christ came to deliver people from it:
“Who gave himself for our sins so that he might deliver us from the present evil aeon according to the will of God the Father.”
—Galatians 1:4
The Creator rules the aeon from which the Father rescues. The Creator’s administration blinds, kills, and condemns. The Father reveals, makes alive, and delivers.
“Just” is not enough to sum up that difference.
Where the Title “Just” Came From
The title predates Harnack by more than seventeen centuries.
Irenaeus reports that Cerdo distinguished the God proclaimed by the Law and prophets from the Father revealed by Christ. The former was known and righteous; the latter was unknown and good. Irenaeus then says that Marcion succeeded Cerdo and developed his teaching (Against Heresies 1.27.1–2).
That report gives us the ancient pair:
- known and righteous;
- unknown and good.
Tertullian attributes a similar distinction directly to Marcion. He describes one God as judicial, fierce, and warlike, and the other as mild, peaceful, and simply good (Against Marcion 1.6).
These are hostile reports. They preserve information, but they also arrange Marcion’s theology for refutation. They should not be treated as though they were verses from the Evangelion or Apostolikon. The historical claim is therefore limited but secure: Harnack did not invent the designation. The ancient heresiologists already used it.
What Harnack Did
Harnack did not create the contrast between the righteous Creator and the good Father. He defended one interpretation of it. In New Studies on Marcion, Harnack discusses Walter Bauer’s objection that “righteous” was not praise at all. Bauer argued that Marcion’s “righteous God” repeatedly shades into an evil God. On this reading, “righteous” functions almost sarcastically. It names punitive justice, not moral excellence.
Harnack rejects that interpretation. He argues that Marcion treated the Creator as the God of the Old Testament and did not regard that God as evil at the root. One of his principal arguments is Romans 7:12, which Marcion retained:
“So then, the Law is holy, and the commandment holy and just and good.” (Romans 7:7 TT)
For Harnack, Marcion could not have considered the God of the Law fundamentally evil while preserving that judgment about the Law.
Harnack’s critics immediately recognized the theological structure of his reading. They accused him of substituting the Pauline-Lutheran opposition of Law and grace, faith and works, for Marcion’s more radical division between two gods.
That criticism reaches the issue directly. Harnack did not invent “righteous.” He stabilized it within a Lutheran framework:
- the Law is genuinely righteous but cannot save;
- the Gospel brings grace;
- the Creator judges;
- the good God does not judge.
Harnack himself acknowledged the longstanding comparison between Marcion and Luther and noted that Neander had drawn it before him. The question is therefore not whether Harnack’s Lutheran background caused him to invent the righteous Creator. It did not. The question is whether that background caused him to emphasize the Creator’s genuine righteousness and reduce the sharper hostility preserved in other reports.
There is good reason to think it did.
Where Our Own Wording Went Too Far
Our own writing has sometimes repeated Harnack’s clean contrast without preserving these distinctions.
“The Creator is just but limited” sounds like a direct doctrinal statement from the True Testament. It is not.
“The Father’s grace and the Creator’s justice” can be useful shorthand, but only if “justice” means the Creator’s legal and retributive administration. It cannot be presented as a moral title bestowed on him by Christ or Paul.
“The Creator’s justice operates on quotas and ledgers” interprets the Law’s operation. It does not quote the True Testament.
“The just Creator proclaimed in the Law and prophets” relies on the ancient reports, particularly Irenaeus and Tertullian. It does not come directly from the Evangelion or Apostolikon.
These sentences are not all false, but they are insufficiently labeled. They allow a reported heresiological title, reinforced by Harnack’s interpretation, to pass as the language of our own canon.
Those sources will be updated in the coming weeks.
A More Accurate Formulation
Instead of saying:
The Creator is just, but the Father is good.
We should say:
The True Testament reserves goodness for the Father. It calls the Law holy and its commandment just and good, but it also calls that Law an administration of death and condemnation that cannot rescue. The Creator is the god of the present aeon, whose rule blinds and from whose order the Father delivers through Christ.
That formulation preserves all the evidence.
It does not call the Creator evil merely because his Law cannot save. It does not call him good merely because the commandment is good. It does not transfer the commandment’s righteousness to the character of its giver. It does not turn Harnack’s interpretation into a verse.
Conclusion
The claim that the Creator is just is not a Harnack creation. Its history goes back to the ancient reports about Cerdo and Marcion. The form in which the claim is commonly repeated, however, shows Harnack’s influence. He defended “righteous” as a genuine moral description of Marcion’s Creator and interpreted the two gods through a Pauline-Lutheran contrast between Law and grace.
The True Testament is more precise. It says the Father alone is good. It says the Law is holy and its commandment just and good. It says the letter kills, the old administration condemns, and the Law cannot accomplish the Father’s rescue. It says the god of this aeon blinds, while the Father sends Christ to deliver people from the present evil aeon.
The Creator is therefore not simply “the Just God.” He is the ruler of the present aeon and the administrator of an order that can command what is just but cannot produce life. “Just” may describe a commandment. “Judicial” may describe his administration. Neither word is sufficient to name his character.
Our own language should now reflect that distinction.
