WELCOME! THE ROMAN MARTYROLOGY The Roman Martyrology (Latin: Martyrologium Romanum ) is the official martyrology of the Catholic Church. Its use is obligatory in matters regarding the Roman Rite liturgy, but dioceses, countries and religious institutes may add duly approved appendices to it. It provides an extensive but not exhaustive list of the saints recognised by the Church. Source: https://en.wikipedia.org/wiki/Roman_Martyrology
