Who they were
Apollinaris was Bishop of Hierapolis in Phrygia in the second century, a Christian apologist famous for his treatises against the heresies of his day.
In 177 he addressed an eloquent Apology for the Christians to Marcus Aurelius, recalling the prayers of the 'Thundering Legion' that won the emperor victory. None of his writings survives.
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 bishop who defended the Christians before the emperor.
