St. Eusebius of Vercelli (283 - 371)

He was born in Sardinia and brought up in Rome, and later (in around 340) was made the first bishop of Vercelli in Piedmont. He lived in a community with his diocesan priests, the first bishop ever to do so.
  He was a strong supporter of orthodoxy, and in 355 was sent into exile by the Emperor for refusing to sign the condemnation of St. Athanasius that had been passed by the Council of Milan. He was in exile for six years, harshly treated by those who had charge of him. On his release he worked hard for unity, but in vain.
  He co-operated with St. Hilary in fighting Arianism, and eventually died peacefully in Vercelli, where a manuscript of the Gospels in his handwriting is preserved.
