Peter of Sebaste
bishop
Feast: 9 January (not on the universal Roman calendar; kept in the Roman Martyrology or local calendars)
Who they were
Peter, youngest brother of Sts Basil, Gregory of Nyssa and Macrina, was formed in the ascetic life by his sister Macrina and helped her monastic community. Ordained by Basil, he lived as a solitary.
About 380 he became Bishop of Sebaste and stood with his brothers against Arianism. He was at the Council of Constantinople in 381, died in 391, and was venerated as a saint.
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 youngest of a family of saints.
