Witnesses of Christ to the sacrifice of their lives
Saints Marius, Martha, Audifax, and Abachus are remembered by the Catholic Church as martyrs of the early centuries of Christianity, and their liturgical memorial falls on January 19. The information concerning them is scarce and fragmentary and comes mainly from ancient hagiographical texts, in particular from a Passio dating to Late Antiquity, which was reworked in subsequent centuries with edifying aims.
