Who they were
Julius, a Roman, was elected pope on 6 February 337. His pontificate is best known for his wise and firm intervention in the Arian controversy, above all his defence of St Athanasius.
He died on 12 April 352 and was honoured as a saint very soon after his death.
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 pope who stood by St Athanasius and the Nicene faith.
