Peter Damian

Peter Damian (c. 1007 – 21 or 22 February 1072 or 1073) was an Italian Benedictine monk and cardinal who worked for reform alongside Pope Leo IX. He was named a Doctor of the Church on 27 September 1828, and his feast day is 21 February. Dante placed him in a high circle of Paradiso, considering him an important forerunner of Francis of Assisi.

Early life

Born in Ravenna around 1007, he was the youngest child of a poor but noble family. Orphaned early, he was first taken in by an older brother who mistreated him, fed him poorly, and made him work as a swineherd.

Later, another brother, Damianus, an archpriest in Ravenna, took pity on him and provided for his education. Peter added his brother’s name to his own and studied theology and canon law in Ravenna, Faenza, and finally at the University of Parma. By about age 25, he was a well-known teacher in Parma and Ravenna.

Religious life

Around 1035, he left his secular career and entered the hermitage of Fonte Avellana near Gubbio, avoiding the wealthier Cluniac monasteries. As a novice and monk, his extreme self-mortification harmed his health and caused severe insomnia. After recovering, he began teaching his fellow monks and, at the request of Guy of Pomposa and other abbots, lectured at neighboring monasteries for two or three years.

Around 1042, he wrote a biography of Romuald for the monks of Pietrapertosa. Soon after returning to Fonte Avellana, he was made house manager by the prior, who named him successor. In 1043, he became prior of Fonte Avellana, a role he held until his death in February 1072.

Under his leadership, new hermitages were founded at San Severino, Gamogna, Acerreta, Murciana, San Salvatore, Sitria, and Ocri. A zealous reformer of monastic and clerical life, he introduced stricter discipline, including the practice of flagellation, which made his house famous and a model for others, even Monte Cassino.

Though many outside his circle opposed such extreme penance, his persistent advocacy won acceptance, though he later had to moderate the zeal of his own hermits. He also introduced the daily siesta to offset the fatigue of night prayers. During his priorate, a cloister was built, silver chalices and a processional cross were purchased, and many books were added to the library.

Reformer

Though living in seclusion, Peter Damian closely followed church affairs. Like his friend Hildebrand (later Pope Gregory VII), he pushed for reform in a troubled era. When Pope Benedict IX resigned in 1045, Damian welcomed the change and urged the new pope, Gregory VI, to address church scandals in Italy, specifically naming the corrupt bishops of Pesaro, Città di Castello, and Fano. He also corresponded with Emperor Henry III, attended the coronation of Henry and his wife Agnes by Pope Clement II, and took part in a Lateran synod in early 1047 that issued decrees against simony.

After returning to his hermitage, he wrote many open letters on theological and disciplinary issues. Around 1050, he published Liber Gomorrhianus, addressed to Pope Leo IX, harshly criticizing simony, clerical concubinage, and sodomy. Around 1053, he wrote Liber Gratissimus, arguing for the validity of ordinations by simoniacal clerics—a position that, though contested, helped decide the matter in their favor by the late 12th century. Pope Benedict XVI later called him "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."

Philosophy

Damian insisted that the liberal arts, including philosophy, must remain subordinate to religion. He argued that monks need not study philosophy, since Jesus did not choose philosophers as disciples, and philosophy is not necessary for salvation. The idea that philosophy should serve theology as a servant serves her mistress—later attributed to Thomas Aquinas—originated with him. His apparent hostility to philosophy may reflect his view that logic deals only with argument validity, not the nature of reality, a position similar to that of Al-Ghazali and Wittgenstein.

His tract De divina omnipotentia defends God’s omnipotence as the ability to do anything good—for instance, God cannot lie. Scholar Toivo J. Holopainen calls it an important early medieval document on modalities and divine omnipotence. Damian also recognized that God can act outside time, a view later held by Gregory of Rimini.

During his illness, the pope died, and Frédéric, abbot of Monte Cassino, was elected.
