Felix and Adauctus
Christian martyrs
Feast: 30 August (1962 Missal, commemoration) · not on the current Roman calendar
Who they were
Felix and Adauctus were martyred at Rome in 303 under Diocletian and Maximian. Their Acts tell that Felix, a Roman priest, was led to execution after refusing to sacrifice, and on the way an unknown man declared himself a Christian and died with him; the Christians called him Adauctus, 'the one added'. The Acts are considered a legendary expansion of an inscription by Pope Damasus, but their veneration is very old.
The miracles
There was never a formal cause: they have been honoured as martyrs since the fourth century; they are commemorated in the Sacramentary of Gregory the Great. Their church stood over their graves in the cemetery of Commodilla near St Paul's.
Why that counted as sanctity
A priest died for Christ, and a stranger, moved by his witness, joined him - so that his name was lost and he is known only as 'the one added'.
