Deuteronomic law requiring a man to marry his deceased brother’s widow

The Deuteronomic law requiring a man to marry his deceased brother’s widow is a scriptural rule at the center of Henry VIII’s challenge to his marriage to Katherine of Aragon. In the novel, its force is inseparable from the political dispute around it: the king seeks a male heir, while the legitimacy of his marriage depends on how scripture, papal dispensation, and competing legal authorities are interpreted.

Scriptural Basis and Disputed Meaning

In a conversation with Thomas Wolsey, Thomas Cromwell identifies Deuteronomy as recommending that a man marry his deceased brother’s wife, and notes that Henry had done so. The passage offers a possible scriptural defense of the marriage, but Henry dislikes the text. Cromwell observes that another biblical rule, in Leviticus, prohibits marrying a brother’s wife and warns that the couple will not have children. The two passages therefore do not deliver a simple, self-evident verdict: their apparent contradiction raises the question of which rule takes precedence.

Wolsey points to an existing resolution of that question. The issue had been considered in Rome by leading prelates, for a substantial fee, when the marriage dispensations were granted and delivered under papal seal. The dispute is thus not only over what the Bible says, but also over whether an authorized ecclesiastical judgment has already settled how its different commands apply. The rule’s political usefulness depends on reopening that settlement.

The Marriage and the Succession Crisis

The law acquires its urgency from Henry’s desire for a son to succeed him. Wolsey frames the king’s predicament against the possibility of a long marriage ending without a male heir, and the conversation turns explicitly to the biblical meaning of “children”: Cromwell points out that Henry has a living daughter, while Wolsey replies that scripture generally uses the term to mean sons. A surviving daughter does not, in the king’s understanding, resolve the succession problem.

Wolsey recalls the couple’s repeated hopes for children and the deaths of male infants, setting those losses beside the survival of Princess Mary. The rule is therefore not an abstract point of interpretation. It is invoked amid the consequences of pregnancy and infant loss, and amid a royal effort to turn the absence of a surviving son into a reason to question the marriage itself.

From Scripture to Royal Proceedings

In May 1527, Wolsey opens a secret court of inquiry at York Place to examine the validity of the marriage. Katherine is neither required to appear nor supposed to know of the proceeding, although its existence becomes known across Europe. Henry is ordered to appear and produce the dispensation that had permitted him to marry his brother’s widow. He does so, confident that the court will find the document defective in some way.

Wolsey is prepared to say that the marriage is open to doubt, but he cannot promise that the legatine court can deliver the outcome Henry wants. Katherine, he expects, will appeal to Rome. The law thus leads from a scriptural tension to a question about the validity of a papal instrument and the authority of the court examining it; the possibility of appeal prevents the initial inquiry from settling the matter.

Jurisdiction and Political Consequences

The later dispute reveals the wider stakes of interpreting the marriage rule. Katherine maintains that her case belongs at Rome and rejects the domestic court convened to decide it. Cromwell, by contrast, urges her to yield for the time being and presents the king’s policy as open to negotiation. Their exchange makes clear that the controversy concerns not only the meaning of Deuteronomy, but also who may give an authoritative judgment on the marriage.

The novel places this controversy within a conflict among scripture, church authority, and royal power. In a later discussion of Marsiglio of Padua’s propositions, Cromwell presents the prince as possessing secular authority over marriage and the distinction between legitimate and illegitimate birth. In Thomas More’s account of a separate dispute, More draws the contrary boundary: Parliament may act in temporal jurisdiction, he argues, but cannot exercise spiritual jurisdiction beyond the realm. Together, these arguments show why the Deuteronomic rule remains politically consequential: deciding how it applies also means deciding which institution has the right to decide.
