**Background:** Religious pluralism in healthcare generates moral disagreements—between clinicians and patients about treatment, among practitioners about procedures they object to on religious grounds, and over prioritising scarce resources. Kirchhoffer rejects both absolute respect for religious belief (which could permit harms like virgin sacrifice) and no recognition of religious belief (which dismisses it as irrational). He argues that neither autonomy nor justice alone can adjudicate such conflicts, and proposes a presumption in favour of religious belief grounded in respect for conscience and human dignity.
**Methods:** This is a theoretical, normative ethical analysis. Kirchhoffer builds his argument by integrating Louis Janssens' personalist anthropology (the 'human person adequately and integrally considered'), a tripartite Roman Catholic conception of conscience, and a multidimensional model of human dignity. He then applies the resulting framework to three hypothetical healthcare cases to illustrate its practical implications.
**Key Results:** Kirchhoffer defines the human person as a meaning-making, embodied subject in relationship to all that is, with eight features: subjectivity, corporeality, being-in-the-world, relationship to others, relationship to institutions, relationship to time/history, openness to transcendent values, and fundamental equality and originality. Conscience has three parts: (1) antecedent conscience—the capacity to identify values and disvalues; (2) moral science—reasoning about competing values; (3) judgement—the binding decision about the good end and right means. Conscience is 'a human person's subjective relationship to objective truth'. Human dignity has four dimensions: (1) inherent dignity as a member of the human species; (2) dignity from capacities (reason, free choice, love); (3) subjective sense of self-worth (acquired or lost); (4) social dignity conferred by others through moral behaviour. The desire for dignity motivates persons to seek truth and act morally, because dignity as self-worth is acquired through morally good behaviour judged by conscience.
From this, Kirchhoffer derives three criteria for morally acceptable beliefs and behaviours in a just public order: (1) they must promote or not violate inherent dignity and the conditions for acquiring dignity as self-worth; (2) they must promote or not violate morally acceptable understandings of dignity as self-worth (i.e., those that do not violate criterion 1); (3) a person cannot be asked to act against conscience unless their judgement is objectively mistaken (i.e., objectively violates criteria 1 or 2).
APPLYING THESE CRITERIA
(a) A doctor objecting to abortion on religious grounds should generally be respected, because whether an embryo is a person cannot be objectively settled with certainty, and alternatives exist. (b) Jehovah's Witness parents refusing life-saving blood transfusion for their infant can be overridden because the infant's life is a precondition for acquiring dignity, so the refusal objectively violates criterion 1. (c) A patient insisting on a ventilator during shortage can have treatment withdrawn if others have better prognosis, because insisting on survival at the cost of others' lives is an objectively mistaken conception of dignity.
**Clinical Implications:** Kirchhoffer argues that religious and moral convictions are rational expressions of the universal human desire to realise inherent dignity as acquired self-worth. Dismissing such beliefs in healthcare risks causing 'existential harm' comparable to physical harm. The framework provides a principled way to balance respect for conscience with justice: beliefs can be overridden only when they objectively violate inherent dignity or morally acceptable acquired dignity of others. The presumption does not preclude dialogue about convictions, especially when coercion or harm is suspected.
