Lore & Background
Orphaned early, he was ill-treated by an elder brother who employed him as a swineherd, but another brother, Damianus, an archpriest, took him to be educated. Adding his brother's name to his own, Peter studied theology and canon law at Ravenna, Faenza, and the University of Parma, becoming a famous teacher by about age 25. After recovery, he lectured to fellow monks and, at the request of Guy of Pomposa and others, lectured at neighboring monasteries. Under his rule, subject-hermitages were founded, and he introduced stricter discipline including flagellation, which became a model for other foundations. He also instituted the daily siesta and oversaw construction of a cloister, purchase of silver chalices and a processional cross, and addition of many books to the library.
Reader's Guide
Peter Damian was a central figure in 11th-century church reform, closely watching the fortunes of the church from his cloister and corresponding with popes and emperors. His insistence that philosophy must remain subservient to religion influenced later thought, and his tract De divina omnipotentia defended divine omnipotence while acknowledging that God cannot lie. His legacy includes his role in shaping monastic discipline, his defense of papal authority, and his recognition as a Doctor of the Church. Pope Benedict XVI described him as 'one of the most significant figures of the 11th century, ... a lover of solitude and at the same time a fearless man of the Church, committed personally to the task of reform.'
