The Oratory in Rome was established in the Trastevere district around 1514-17, where both prelates and laymen would meet in the church of Santi Silvestri e Dorotea frequently to discuss ecclesiastical reform. It was modelled on Genoa but its membership was more exclusive, with 50 (mainly aristocratic) members. Pope Leo X formally approved the rule on 24 March 1514, which meant membership was restricted to 36 laymen and four priests. The rule prescribed a fixed program of prayers, a weekly fast, monthly confession, and Communion four times a year. Members of the Oratory cared for orphans, helped the poor, consoled imprisoned criminals, and attended the sick in hospital. To facilitate their work throughout all classes of society, the names of the members of the oratory and its program were kept secret from others. It was finally disbanded at the Sack of Rome in 1527, but its spirit survived in the hospital for incurables of S. Giacomo in Augusta and in the reform measures championed by its members, such as Gian Matteo Giberti, Bishop of Verona, Gaetano da Thiene and Gian Pietro Carafa, as well as Jacopo Sadoleto, Luigi Lippomano, and Gasparo Contarini.
