Hosius of Corduba
Spanish bishop (256–359)
Feast: 27 August (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Hosius, a confessor in the persecution, became Bishop of Córdoba about 295. The foremost Western champion of orthodoxy against Arius, he was adviser to Constantine and presided at the Council of Nicaea.
In old age he refused to condemn St Athanasius and wrote a brave protest to Emperor Constantius against imperial meddling in Church affairs. At Sirmium, under pressure, he signed an Arian formula; a later account says he recanted on his deathbed. He died about 358.
The miracles
The Catholic Encyclopedia does not describe how he came to be honoured as a saint.
Why that counted as sanctity
A great defender of the Nicene faith.
