Marriage prohibitions based on kinship and affinity

Marriage prohibitions based on kinship and affinity are presented as both legal constraints and instruments in the struggle over Henry VIII’s marriage and the authority to decide it. The novel places the question of whether a prior relationship with one sister bars marriage to another inside a larger contest among canon law, royal counsel, Parliament, and claims to spiritual jurisdiction.

The marriage question

As Henry VIII seeks to marry Anne Boleyn, the impediment posed by his earlier relationship with Mary Boleyn becomes a practical obstacle. Mercy asks Thomas Cromwell whether the proposed marriage to Anne is incestuous because Mary had been in the king’s bed. Cromwell answers that the question has been examined by religious scholars: Thomas Cranmer, acting on Cromwell’s recommendation, sent to Venice for learned Jewish opinions on the meaning of ancient texts. Their conclusion, as Cromwell reports it, is that the marriage is not incestuous unless the king had actually been married to Mary.

The exchange makes clear that the ruling is not simply a private theological matter. Mercy asks what the inquiry cost, and Cromwell explains that scholars and priests negotiate separately from the person who brings the money. Her blunt response is that this arrangement does little to strengthen the case. The scene shows the legal and theological question being pursued through counsel, scholarship, and payment, while also revealing how little certainty Cromwell himself claims: he concedes that there is no help for his own position.

Competing jurisdictions

The rule’s force depends on which authority is allowed to interpret it. In conversation with Katherine of Aragon and Mary Tudor, Cromwell argues that the king has not been led into declaring himself head of the English Church; he presents the change as a position grounded in ancient precedent. Katherine counters that those precedents have been invented only recently, and Mary asks whether what has been defined can later be redefined. Cromwell answers that it can, leaving room for negotiation rather than treating the new arrangement as irrevocable.

Katherine’s refusal to accept the proceedings at Dunstable gives the jurisdictional dispute a concrete form. She maintains that her case remains at Rome and rejects Thomas Cranmer’s authority as that of an archbishop she does not recognize. Cromwell urges her to yield for the present and warns that treason law could apply if she were found to be acting against the king; Katherine insists that she will not attend the court and denies that an invasion will occur in her name. The unresolved marriage question thus sits amid a direct conflict over whether the case belongs to the English court, the king’s authority, or the Pope.

Royal power and the law

Cromwell later uses Marsiglio of Padua’s propositions to explain to Henry VIII a theory of secular jurisdiction. In this account, Christ did not make popes or authorize churchmen to govern through lawmaking and taxation; priests remain subjects, while the prince governs matters including who may marry and who is legitimate. The king’s authority, Cromwell says, comes through Parliament, which acts on behalf of the people.

That theory does not settle the conflict so much as clarify its stakes. In the argument reported by Richard Riche, Thomas More distinguishes temporal jurisdiction from spiritual jurisdiction: Parliament could, in his view, make a king, but could not make the king head of the Church, because spiritual jurisdiction lay outside the realm. Cromwell recognizes the political danger in that distinction, since denying Parliament’s capacity to confer religious authority could be treated as denying the king’s title. The marriage prohibitions therefore belong to a wider struggle over who can classify a marriage, define legitimacy, and make a legal decision binding.

Narrative significance

The novel connects the rules of affinity to the machinery of political change rather than presenting them as a self-contained body of doctrine. Scholarly interpretation is sought abroad; court proceedings are contested; royal policy is given legislative form; and opposing claims of spiritual authority remain active even when the king’s government asserts its power. The result is a portrait of legal pluralism in which the same marriage can be approached through different sources of authority, with consequences for the queen, the succession, and the standing of the Church.
