Is marriage a covenant (breakable by treachery) or an indissoluble one-flesh bond?

Type: supporting argument (off-timeline) · Assessment: contested — the advocated claim that marriage is a covenant — a relationship of obligation ratified by oath — and that, like other covenants, it can be broken by the treachery of a party (adultery, or the “violence” of a treacherous divorce), so a grievous breach genuinely dissolves the bond and frees the wronged party, as against the ontological “one flesh” model on which the union is a metaphysical reality that can only be violated, never broken while both live. The covenant model of marriage is well-grounded and rightly displaces a crude fusion-caricature; but that being a covenant entails dissolubility does not follow — covenant is a genus with both breakable and unbreakable members, and the indissolubilist tradition itself calls marriage a covenant · the definitional foundation under the indissoluble-bond and remarriage-or-separation disputes

The claim

…an elected, as opposed to natural, relationship of obligation under oath.

— Gordon P. Hugenberger’s working definition of covenant, Marriage as a Covenant (Brill, 1994), p. 11. The claim underneath the whole dissolution dispute is a definitional one: what is a marriage? On the covenant model it is not a metaphysical fusion of two persons into one indivisible substance but a relationship of mutual obligation, entered by consent and ratified by oath — and a covenant, unlike a fused substance, is the kind of thing that can be kept or betrayed. If marriage is a covenant, then (the argument runs) covenant-treachery — adultery, desertion, the “violence” of unjust divorce — is a real breaking of the bond that releases the party sinned against, exactly as the breach of any covenant discharges the faithful party from its obligations. Against this stands the model that reads “the two shall be one flesh” as an ontological joining God performs (“what God hath joined together”), so that a valid marriage is a real and permanent union no human treachery can sever — it can be sinned against, but not dissolved, while both spouses live.

Who advances it

The covenant model is the common property of the traditions that permit remarriage of the innocent party, though they reach it by different routes. Its fullest modern scholarly statement is Gordon P. Hugenberger’s Marriage as a Covenant (1994), built from Malachi 2:14 (“the wife of thy covenant”): a marriage becomes a covenant through a ratifying oath — the sine qua non of any covenant — sworn in the verba solemnia and sealed by the oath-sign of sexual union, not by a bride-price transaction. The Reformed tradition draws the dissolution consequence directly: John Murray’s Divorce (1953) argues that when a husband puts away his wife for fornication “this putting away has the effect of dissolving the bond of marriage,” so that the parties “are no longer man and wife” and the innocent may remarry — the position already fixed confessionally in the Westminster Confession (ch. 24), which grants that adultery and wilful desertion break the covenant and free the innocent to marry “as if the offending party were dead.” The rabbinics scholar David Instone-Brewer supplies the ancient-Near-Eastern frame: Old-Testament marriage was formalized by a ketubah-style marriage contract stipulating the obligations of food, clothing, and conjugal love (Exodus 21:10–11), whose neglect freed the wronged spouse — a covenant with stipulations whose breach carried consequences. The rival ontological model is Augustine’s marriage sacramentum and the Roman Catholic bond (weighed on the indissoluble-bond page): a valid, consummated marriage “can be dissolved by no human power and by no cause, except death.”¹

The case for

Scripture’s own vocabulary for marriage is covenantal, not metaphysical. When the Bible names what a marriage is, it reaches for covenant language, not the language of substance or fusion. Malachi calls the wife “thy companion, and the wife of thy covenant [bərît]” (Malachi 2:14), with the Lord standing as “witness” — the posture of a party to an oath, not a spectator of a metaphysical event. Proverbs calls the adulteress one who “forsaketh the guide of her youth, and forgetteth the covenant of her God” (Proverbs 2:17). And the prophets build the entire figure of God’s marriage to Israel on the covenant frame — “I sware unto thee, and entered into a covenant with thee… and thou becamest mine” (Ezekiel 16:8), the whole enacted in Hosea’s marriage to Gomer. That God can be a faithful covenant husband to a treacherous wife — and can, in the figure, put her away and take her back — presupposes exactly the covenant category the model claims: a bond of sworn obligation that one party can betray.²

A covenant is the kind of thing treachery can break. Where a metaphysical fusion, once real, is simply a fact about the world that persists until death undoes it, a covenant is a relationship of obligation, and obligations can be repudiated. Malachi’s indictment turns on precisely this: the men are charged with dealing treacherously (bagad) against the wife of their covenant (Malachi 2:14–16) — the language of covenant-breaking — and on the third-person reading of v. 16 the “man who hates and divorces… covers his garment with violence,” a censure of the treacherous divorce as covenant-violence, not a metaphysical impossibility. If adultery and treacherous desertion are breaches of covenant, then on the ordinary logic of covenants they discharge the faithful party: this is the exegetical hinge on which the Reformers, Murray, and the Westminster divines rest the innocent party’s freedom — the offender, by the breach, “is considered as one dead,” and the bond he swore and broke no longer binds the one he betrayed.³

“One flesh” underdetermines the fusion model. The ontological reading leans wholly on “they twain shall be one flesh” (Genesis 2:24) as naming an indivisible metaphysical union. But “one flesh” is kinship-and-consummation language, not fusion-of-substance language: Paul uses the very phrase of a man’s union with a prostitute — “he which is joined to an harlot is one body? for two, saith he, shall be one flesh” (1 Corinthians 6:16) — a real bodily one-flesh that plainly does not create an indissoluble marriage. So “one flesh” cannot by itself carry the freight of permanent ontological union; the permanence, if it is there, must come from the covenant sworn over the union, which is what the model says marriage fundamentally is. On this reading Jesus’ “what God hath joined together” forbids treacherous sundering (the sin Malachi attacks) without asserting that a betrayed covenant remains metaphysically intact.⁴

Adversarial assessment

What holds. As a model of marriage the covenant reading is strong, and it corrects a real caricature. Scripture’s settled vocabulary for the marriage bond is covenantal (Malachi 2:14; Proverbs 2:17; Ezekiel 16:8), and covenant is a relational, oath-bound category, not a metaphysical-fusion one — so a picture of marriage as two persons melted into one indivisible substance, which no treachery can touch, is not straightforwardly the Bible’s own picture. Covenant-treachery is a genuine biblical category with genuine consequences, and the appeal to it to explain how an innocent party can be released is not an evasion but a recognized reading of the texts. To that extent the covenant model reframes the dissolution dispute honestly, at the definitional level the whole debate presupposes and rarely states.

What is overstated or imprecise. The advocated inference — covenant, therefore dissoluble by breach — does not follow, and four things keep it short of settling the question. (1) Covenant does not entail dissolubility; the category equivocates. Many biblical covenants are precisely permanent and unbreakable: the Noahic covenant is an “everlasting covenant” God will never revoke (Genesis 9:16), and the Davidic covenant stands though its heirs prove faithless — “My covenant will I not break… I will not lie unto David” (Psalm 89:34–35). “It is a covenant” is therefore compatible with “it cannot be broken”; the word supplies a genus, and whether marriage is a breakable or an unbreakable covenant is exactly the disputed point, not something the label decides. (2) The indissolubilist tradition itself calls marriage a covenant — so the dichotomy is partly false. The Catechism of the Catholic Church opens its treatment, “The matrimonial covenant… has been raised by Christ the Lord to the dignity of a sacrament” (§1601), and current canon law defines marriage by the “matrimonial covenant” (foedus, can. 1055) while holding a ratified and consummated one dissoluble by nothing but death (can. 1141). The covenant-vs-ontology contest is thus not “covenant” against “bond,” but a dispute over what kind of covenant marriage is — which throws the weight back onto the exegetical dissolution question, not the definitional label. (3) The proponent’s own case is narrower than the thesis built on it. Hugenberger does not argue that any breach dissolves a marriage at will; his conclusion is that Malachi condemns treacherous, aversion-driven divorce and is consistent with the Mosaic permission of Deuteronomy 24 — a carefully bounded position, not a general dissolubility principle, so resting “covenant breach dissolves the bond” on his covenant work overstates him. (4) “One flesh” still pulls the other way. That Paul can call union with a harlot “one flesh” loosens the fusion reading, but Jesus grounds the prohibition of divorce squarely in the one-flesh creation joining (“they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder” — Matthew 19:6), which the covenant model must still reckon with: covenant-hood does not by itself cancel a divine joining, and the indissolubilist reads that joining as the thing no covenant-breach can undo.⁵

Assessment

Contested. As a model of what marriage is, the covenant reading is well-grounded — arguably the sounder picture: Scripture’s own language for the bond is overwhelmingly covenantal (the “wife of thy covenant,” the “covenant of her God,” God’s covenant-marriage to Israel), and covenant is a relationship of sworn obligation, not a fusion of substance, which rightly corrects the crudest form of the ontological picture. But the advocated claim — that being a covenant entails that treachery dissolves the bond and frees the wronged party — does not hold on the covenant label alone. Covenant is a genus that in Scripture includes both breakable and expressly unbreakable members (the everlasting Noahic and Davidic covenants), so “it is a covenant” settles nothing about dissolubility; and the indissolubilist tradition itself defines marriage as a covenant while denying it can be broken, which turns the supposed covenant-vs-ontology contest into a dispute over what kind of covenant marriage is. The model therefore reframes the dissolution debate at the definitional level — a real service — but it cannot settle it: the weight falls back onto the exegetical question of whether the exception permits remarriage or only separation and the affirmative indissoluble-bond thesis, both themselves contested. The rendering of the covenant text it leans on (Malachi 2:16) is likewise contested, and the proponent’s own conclusion there is the bounded one that Malachi condemns treacherous divorce, not that any breach dissolves. Contested.
