Nilus the Younger
Italian saint
Feast: 26 September (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Nilus of Rossano, after a life he later repented, was converted through sickness and became a monk, spreading the rule of St Basil in Italy, known for his ascetic life and learning.
He opposed the antipope Philagathos, yet rebuked the pope and emperor for his cruel mutilation. He founded the Greek monastery of Grottaferrata near Frascati and died on 27 December 1005.
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 converted sinner who became a founder of monasteries.
