Conscience, confession and discretion: a Catholic financial culture

The seal and the secret

The Catholic reform made confession the centre of religious discipline. The Fourth Lateran Council of 1215 had already obliged every Christian to confess at least once a year to his own parish priest and had imposed on the confessor an absolute duty of secrecy. Trent confirmed the sacrament against the Reformers and defined its elements. Borromeo gave it a physical form: he introduced the enclosed confessional with a grille between priest and penitent, a piece of church furniture that spread from Milan throughout the Catholic world.¹ Confession was private, regular and comprehensive. The penitent was to examine his conscience on all his acts, including his contracts, debts, inheritances and dealings with servants and tenants. The confessor was to judge them, impose penance and, where necessary, require restitution. The duty of secrecy that protected this exchange was and is absolute. The Catechism of the Catholic Church states that "the sacramental seal is inviolable; therefore, it is a crime for a confessor in any way to betray a penitent by word or in any other manner or for any reason".² The Code of Canon Law forbids the confessor to betray a penitent in any way and punishes a direct violation of the seal with automatic (latae sententiae) excommunication.³ Beside this absolute secret the Catechism recognizes professional secrets, which bind "political office holders, soldiers, physicians, and lawyers" and other confidants. These are to be kept, save in exceptional cases where keeping the secret is bound to cause very grave harm to the one who confided it, to the one who received it or to a third party, and where that harm can be avoided only by divulging the truth. Even private information prejudicial to another is not to be divulged without a grave and proportionate reason.⁴

The structure of this teaching corresponds closely to the modern law of professional secrecy. The confessor's seal is an absolute privilege. Professional secrets are protected as a rule but yield to an overriding interest in exceptional cases defined by law. Swiss criminal law punishes, on complaint, any person who discloses confidential information confided to him "in his capacity as a member of the clergy, lawyer, defence lawyer, notary, patent attorney, auditor" or physician, among other professions, with a custodial sentence of up to three years or a monetary penalty. Disclosure is not punishable with the consent of the person concerned or with the written authorization of a superior or supervisory authority (Art. 321 SCC).⁵ Swiss criminal procedure grants members of the clergy, lawyers, notaries, doctors and the other listed professions a right to refuse to testify on confidential matters that came to their knowledge in their professional work (Art. 171 para. 1 CrimPC).⁶ The banker's secret is protected by a separate provision of the Banking Act (Art. 47 BankA), which Chapter D.I traces to its introduction in 1934 and Chapter E.II follows to its present limits.⁷ The Catholic clergy thus appear in the same provision of the Criminal Code as the lawyers and notaries who advise the clients of the Lugano financial centre, a reminder that the legal protection of confidences in Swiss law has a religious root alongside its civil and commercial ones.
