Flavian of Constantinople
5th-century Archbishop of Constantinople
Feast: 17 February (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Flavian, a priest of Constantinople known for his holy life, became its bishop against the wishes of the powerful eunuch Chrysaphius, and refused to give him church treasures.
At his council in 448 the monk Eutyches was condemned for heresy. At the Robber Council of Ephesus in 449 Flavian was deposed and so ill-treated that he died three days later in exile at Hypaepa. He was repeatedly vindicated and his body brought back in triumph.
The miracles
There was never a formal cause: he has been honoured as a saint since before the Church's formal processes began.
Why that counted as sanctity
A patriarch who died for the true faith about Christ.
