How do you tell the difference between a creation-order command and a covenant-context instruction?

The diagnostic question is short. It does the work that interpretive grids cannot:

Does the text itself ground this command in Genesis 1-3 — or does it name a different basis?

If the text invokes creation order, the command is Category I (creation-order, transcovenantal). If the text names a different basis — biology of the sign, sanctuary purity, judicial procedure, patrilineal name-preservation, household-head institution, missional pressure — the command is Category II (covenant-context), and its scope moves with its basis.

The empirical floor: 0 of 10 Torah anchor passages cite creation order.

A canon-scale survey of the Torah passages most often cited as patriarchal anchors yields a striking result. Across the ten anchor passages, zero invoke Genesis 1-3 as the rationale. The basis the text actually gives in each case:

Zero of ten cite Genesis 1-3. Each one names its own basis: biology, institution, judicial procedure, patrilineal preservation, protective principle. The Torah's own taxonomy is honest about why a command goes the way it does. Modern readers often bypass that taxonomy and import a creation-order frame the text never invokes.

The few passages that DO invoke creation order — and what they hold.

A small set of NT passages explicitly ground a sex-related instruction in Genesis 1-2. The gar clause of 1 Timothy 2:13-14 is the clearest example:

Ἀδὰμ γὰρ πρῶτος ἐπλάσθη, εἶτα Εὕα. καὶ Ἀδὰμ οὐκ ἠπατήθη, ἡ δὲ γυνὴ ἐξαπατηθεῖσα ἐν παραβάσει γέγονεν. — 1 Timothy 2:13-14

The conjunction γάρ (gar, "for") is the standard Pauline grounding-particle. The verb ἐπλάσθη (eplasthē, V-API-3S, "was formed/moulded") is from πλάσσω (plassō, G4111) — and it is the same verb the LXX uses at Genesis 2:7 (καὶ ἔπλασεν ὁ θεὸς τὸν ἄνθρωπον). Paul is verbally echoing LXX Gen 2:7. Pattern-comparison between 1 Tim 2:13-14 and Gen 2:7-3:13 yields ~56 percent coverage. This is gar-grounded creation-order argumentation in the strict sense.

Two other clear creation-order grounds in the NT:

• Marriage and one-flesh union — Jesus quotes Genesis 2:24 as creation-design: οὐκ ἀνέγνωτε ὅτι ὁ ποιήσας ἀπ' ἀρχῆς ἄρσεν καὶ θῆλυ ἐποίησεν αὐτούς (Mat 19:4). Paul amplifies in Eph 5:31-32, citing LXX Gen 2:24 verbatim and naming the union μυστήριον. The marriage-pattern is grounded in Gen 1-2.
• Husband's agapaō love-command — Eph 5:25-32 grounds the husband's love in (i) Gen 2:24 cited in vv. 31-32 and (ii) the Christ-church μυστήριον. The form is paredōken heauton hyper autēs — Christ's cross-shape (~67% pattern overlap with Eph 5:2).

What this looks like in the synthesis: image, dominion, one-flesh, agapaō-as-Christ-cross, and the gar-grounded posture-of-learning at 1 Tim 2:11-13 are the principal Category I items. Each holds across covenants; each is grounded in Genesis 1-2 by the text itself or by an NT writer who explicitly cites that grounding.

Where the basis is biology or institution, the command moves with the basis.

Three illustrations:

(i) Circumcision is Category II — biology of the sign. Gen 17:11 grounds the command in the biology of the male (בְּשַׂר עָרְלָה). The NT does not abolish the substance; it universalises it. Romans 2:29 — περιτομὴ καρδίας ("circumcision of the heart") — and Colossians 2:11 — περιετμήθητε περιτομῇ ἀχειροποιήτῳ ("you were circumcised with a circumcision not made by hands") — apply the substance to all believers, both sexes. The biology of the sign was the basis; once Christ comes, the sign is fulfilled and the substance is inherited by all in him.

(ii) The Levitical priesthood is Category II — sacrificial-functional. Kohen (H3548) is grammatically masculine in 711 occurrences; the priesthood in Lev 8 and Lev 21:6 is institutional and sacrificial. Hebrews 7 declares Christ the priest who fulfils the office. 1 Peter 2:9 — ὑμεῖς δὲ γένος ἐκλεκτόν, βασίλειον ἱεράτευμα ("but you are a chosen race, a royal priesthood") — applies the substance to all believers, both sexes. The institutional shape gave way to its eschatological fulfilment.

(iii) The 1 Corinthians 14 sigaō is Category II — situational disorder. Sigaō (G4601) is paired with two other sigaō triggers in the same chapter (vv. 28, 30 — the tongues-speaker without an interpreter is to σιγάτω; the prophet whose word is being judged is to σιγάτω). The whole chapter is calibrated to εὐσχημόνως καὶ κατὰ τάξιν (v. 40, "decently and in order"). The basis is congregational order, not creation. The same letter (1 Cor 11:5) assumes women are praying and prophesying.

The pattern: when the basis is biology, the command stays under biology; when the basis is institution, it transitions in Christ; when the basis is missional or congregational order, it adapts to the mission.

Three failure modes the diagnostic prevents.

1. Importing creation-order frames the text never invokes. Levirate and yibbum (Deu 25:5-10) are sometimes read as patriarchal grounding for male precedence. The text grounds the command in name-preservation, not creation. The diagnostic catches this.

2. Flattening Category I and Category II together. Treating the husband's agapaō (Cat I, grounded in Gen 2:24 and Christ-church mystērion) and the husband's circumcision obligation (Cat II, grounded in Gen 17:11 biology) as the same kind of command. They are different categories with different stated bases.

3. Treating Category III as Category I. Reading the head-covering register (1 Cor 11:13's prepon) as a transcovenantal command rather than a culturally-engaged convention. The diagnostic — "what does the text say is the basis?" — catches the conflation.

The diagnostic is not a license to dispense with hard texts. It is the discipline of letting the text say what it says is the basis, and then letting the scope of the command move with the basis the text names.
