Who they were
In Persia, the holy martyrs John, a bishop, and James, a priest, who under King Shapur II were thrown into prison and after a year ended their glorious struggle, pierced by the sword.
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
The Roman Martyrology remembers him on 23 October as a bishop in Persia who was imprisoned under King Shapur II and put to the sword after a year.
