Religious uniformity and coexistence among faiths

Religious uniformity and coexistence among faiths defines one of the novel’s most consequential disputes about how a country should be made. Catalina first understands pluralism as a political model grounded in law and peaceful government, even as her parents’ rule abandons its promises. Her later encounter with a Moorish physician turns that contradiction into a personal reckoning: she retains her Christian faith but can no longer accept that religious difference makes other people enemies or barbarians.

A model of government beyond uniformity

Catalina’s defense of coexistence is connected to an account of government she associates with al-Andalus, the Moorish lands. In conversation with Arthur, Prince of Wales, she argues that effective rule depends on law reaching everyone, rather than each lord acting as the final authority in his own territory. She presents the Moors as having established peace and prosperity without requiring people to change either their religion or their language. In this account, shared law—not shared belief—is what permits a diverse population to live together.

That comparison matters in the Welsh borderlands, where authority is fragmented among landowners and local leaders. Arthur is trying to persuade chieftains to settle disputes, make good wrongs, and cooperate rather than continue feuds. Catalina’s example offers him a political alternative to government by force or personal allegiance: law can bind people who differ from one another. Her principle is not simply a defense of religious tolerance; it is part of a broader argument about how lawful administration might replace local disorder.

She also points to practical institutions that could support such rule. When Arthur considers the problem of dishonest tax collectors, Catalina recalls that Moorish rulers established schools and universities, enabling them to find educated clerks they could trust. She describes public service as something that should depend on training and reliable payment, not private enrichment. In her account, learning and administration help make fair government possible. The ideal of coexistence therefore rests not only on goodwill but on institutions capable of serving a population without demanding that it become religiously uniform.

The promise and its reversal

Catalina’s political example is complicated by what her parents’ government does after victory. The victors promise that Muslims will be safe under Christian rule as Christians had been under theirs, and the promise of convivencia invites Moors, Christians, and Jews to expect lives of security and self-respect. The account makes clear that this promise is not kept: within three months, Jews are expelled and Muslims are threatened with conversion or departure. Religious difference, previously compatible with public order, is recast as an obstacle to making one country and one people.

The policy is presented as purposeful state-building. Its advocates treat one faith as the necessary basis of national unity and subject suspected dissent to the Spanish Inquisition. But Catalina’s story exposes the contradiction between that rationale and the prior pledge. Her parents’ authority had drawn upon the political and cultural inheritance of the society they conquered; it nevertheless turned away from coexistence when uniformity appeared to offer a firmer basis for rule. The change makes conquest’s promises politically fragile: the terms offered to a defeated population can be withdrawn when they conflict with the victors’ preferred account of unity.

A debate about Christian rule

In the Welsh discussions, Catalina does not begin as an uncomplicated advocate for religious freedom. When Arthur asks whether a Christian king must bring his subjects to one faith, she answers that a Christian ruler has a duty to bring them to God. She recognizes that her parents have begun to impose their religion and that Jews have already been driven out, yet she distinguishes their intention at the time of the conquest from the suffering their later policy causes. Her position holds two principles in tension: she believes in Christian responsibility, but she also believes that the original promise was to let people practise their faiths.

Arthur presses the point by observing that her parents are now imposing the very religious conformity their earlier promise seemed to exclude. Their exchange does not settle the question through a simple conversion to one side. Instead, it reveals how readily a language of religious duty can support coercive rule, and how difficult it is for Catalina to reconcile that duty with the coexistence she remembers. Her political ideal, as she expresses it, is a country with one law and many faiths and languages, whose people are trusted to choose among them. The ideal is especially striking because she voices it within a Christian account of kingship rather than as a rejection of her own religion.

Experience changes the meaning of difference

Catalina’s understanding shifts further after a Moorish physician treats her with kindness. She recalls that he saw her in a vulnerable state yet responded with compassion, and that this experience makes it impossible for her to dismiss the Moors as savages. She allows that he may be mistaken in religious matters, but also recognizes his right to reach conclusions for reasons of his own. Difference is no longer an abstraction to be managed from a distance: she has met it in a person whose conduct challenges the categories she inherited.

That reassessment widens into a critique of her mother’s policies. Catalina connects the physician’s presence to the knowledge Spain has driven away: Jewish skills and courage, and Moorish scholarship and gifts. She sees a painful contradiction in a ruler who admired learning while banishing communities associated with it, and who fought for justice while acting unjustly toward them. Her criticism reaches beyond the physician’s individual kindness to the consequences of religious exclusion for medicine, science, and public knowledge.

The change does not mean that Catalina abandons Christian belief. She says that her faith remains firm, but she no longer regards her mother as infallible or assumes that her mother’s judgments and God’s will are identical. She rejects a crusade against the Moors and opposition to people on the basis of their skin or belief. What changes is the boundary she draws between religious conviction and persecution: faith no longer licenses her to treat those who hold another creed as devoid of moral worth.

Political and narrative significance

The novel places the principle of coexistence under pressure from both public policy and intimate experience. At the level of government, the contrast is between law that can hold a diverse population together and a program that makes religious sameness a test of belonging. At the level of Catalina’s development, the contrast is between inherited certainty and judgment revised through encounter. Her early political discussions make pluralism a question of administration and kingship; the physician’s compassion makes it a question of how she sees other people.

That movement also prevents the ideal from becoming a claim that Catalina’s parents consistently practised what they once promised. She can remember the value of the promise while acknowledging its betrayal and the suffering that followed. The resulting position is more critical than nostalgia for a lost order: it asks whether a ruler can establish peace by law without demanding uniform belief, and what a country loses when it expels people and knowledge in the name of religious unity. Catalina’s answer emerges through her changed judgment, not through a renunciation of Christianity: a shared faith cannot be made the price of justice, and religious difference need not prevent people from living under common law.
