Eusebius of Vercelli
Catholic bishop and saint
Feast: 2 August (current Roman calendar, optional memorial) · 16 December (1962 Missal, III class)
Who they were
Eusebius was born in Sardinia around 283 and went young to Rome to study, where he was baptised and became friends with the future Pope Liberius; together they met St Athanasius, exiled by the Arians, and through him learned of St Anthony's monastic life. In 342 Pope Julius sent him to the Western emperor Constans about founding a diocese at Vercelli, and the people there chose him as their first bishop; he was consecrated on 15 December 345.
He lived in community with his clergy, joining priestly work to monastic prayer and penance; St Ambrose wrote that he was the first in the West to unite the life of the clergy with the life of monks. For defending the faith of Nicaea he was exiled under the emperor Constantius, writing from exile to urge his people to keep the faith and stay united. Julian allowed the bishops to return, and Eusebius came home in 363, eight years after his exile. He died on 1 August 371.
The miracles
There was never a formal cause: Eusebius has been honoured as a saint since his death.
Why that counted as sanctity
Eusebius built up a Church in the countryside and mountains, formed a community of priests living as monks, and suffered years of exile rather than give up the faith in Christ's divinity.
