How to read this record
Passages side by side
TextThe primary text, as seeded. Nothing here is summarised or paraphrased.
And Jacob begat Joseph the husband of Mary, of whom was born Jesus, who is called Christ.
And Jesus himself began to be about thirty years of age, being (as was supposed) the son of Joseph, which was the son of Heli,
Why they appear to conflict
AnalysisEach side states a proposition attributable to its passages. A claim is not assumed to have exactly two sides.
Matthew
Jacob was the father of Joseph.
Jacob
Matthew 1:16
Luke
Joseph was the son of Heli.
Heli
Luke 3:23
Formal analysis
AnalysisA contradiction requires a proposition and its incompatible counterpart under materially equivalent conditions. Every dimension below must hold for the formal test to succeed.
Proposition A
father_of(Joseph) = JacobProposition B
father_of(Joseph) = Heli| Dimension | Question | Assessment |
|---|---|---|
| Same subject | Do both propositions predicate of the same subject? | Yes |
| Same referent | Do the referring expressions pick out the same individual? | Uncertain |
| Same event | Do both describe the same event token, not merely the same event type? | Not applicable |
| Same time | Do both describe the same time or time-window? | Not applicable |
| Same sense | Are the key terms used in the same sense? | Uncertain |
| Same scope | Are quantifiers, counting criteria and boundaries the same? | Yes |
| Same textual tradition | Are both readings secure in the same textual tradition? | Yes |
Both lists name the same Joseph, so the subject is secure. What is unresolved is whether "son of" carries the same sense in both — biological paternity in each, or legal or adoptive descent in one — and whether Luke’s referent at that point is Joseph at all. Those two questions are what every proposed reconciliation addresses.
Analytical questions
AnalysisWhat a researcher must answer to classify this record. Open questions are recorded, not resolved by preference.
- Does either genealogy signal that it traces a line other than biological paternity?
- Does Luke’s "as was supposed" qualify only the relation of Jesus to Joseph, or extend further down the list?
- Does the Greek of Luke 3:23 permit reading Heli as Mary’s father?
- Are levirate or adoptive relations attested anywhere in either genealogy’s own framing?
Hebrew / Greek relevance
LanguageWhether Luke 3:23 can be read as tracing Mary’s line depends on the Greek syntax of the parenthesis and the article usage; it cannot be settled from the English.

Narrator and speaker analysis

No narrator or speaker analysis has been recorded for these passages yet.
Proposed harmonisations
InterpretationEach proposal records the premises it must supply that the text does not state. Premises are never injected silently.
Luke traces Mary’s line
Luke gives Mary’s genealogy, with Joseph named because genealogies were reckoned through men.
Premises this proposal must supply
- historicalHeli was Mary’s father, not Joseph’s.
- textualLuke intends the list to run through Mary despite naming Joseph.
Editorial Harmonisation Cost Heuristic
4 / 5 — Multiple substantial unstated premises
Luke names Joseph, not Mary, at the head of the list. The reading requires both a suppressed subject and an unstated relation. Multiple substantial unstated premises.
Reviewed by CodexTrace Editorial Board on 2026-09-07. This is an editorial heuristic, not an objective measurement.
Levirate or adoptive relation
One genealogy gives the legal father and the other the biological father, under a levirate or adoptive arrangement.
Premises this proposal must supply
- historicalSuch an arrangement existed in Joseph’s immediate ancestry.
Critical responses
InterpretationArguments that the proposed reconciliations do not succeed, treated structurally the same way as the harmonisations.
No critical response has been recorded for this claim yet.
