Simplicius, Faustinus and Beatrix
Christian saints and martyrs
Feast: 29 July (1962 Missal, commemoration) · not on the current Roman calendar
Who they were
The brothers Simplicius and Faustinus were martyred at Rome in Diocletian's persecution around 302-303, beaten and beheaded, and their bodies thrown into the Tiber. Their sister Beatrix drew them out and buried them, then lived seven months with a devout woman, Lucina, helping persecuted Christians day and night.
Denounced by a neighbour who coveted her land, she told the judge she would never sacrifice to demons because she was a Christian, and was strangled in prison. Lucina buried her beside her brothers on the road to Porto.
The miracles
There was never a formal cause: they have been honoured as martyrs since the early centuries.
Why that counted as sanctity
A sister buried her martyred brothers, served the persecuted and then shared their death for Christ.
