Peter Damian
eleventh-century Benedictine monk
Feast: 21 February (current Roman calendar, optional memorial) · 23 February (1962 Missal, III class)
Who they were
Peter was born at Ravenna in 1007, the youngest of seven; his mother at first refused to feed him, until a neighbour shamed her. Orphaned, he was ill-treated by one brother until his eldest brother Damian, an archpriest near Ravenna, took him in and educated him; in gratitude Peter added his name to his own.
He became a monk of Fonte Avellana and a tireless reformer of the Church, working for the freedom of the Church from lay control in the struggle that ended, after his death, with the emperor kneeling as a penitent before the Pope at Canossa in 1077. Returning from a peace mission to Ravenna, he died at the Benedictine monastery of Santa Maria fuori Porta in Faenza.
The miracles
There was never a formal cause: the people acclaimed him a saint at his funeral. Pope Leo XII declared him a Doctor of the Church in 1828.
Why that counted as sanctity
Peter Damian, rescued from a loveless childhood, gave himself to God as a monk and spent his strength calling the Church, from clergy to emperor, back to holiness and freedom.
