Gregory Celli (1225?-1343?) is an example of the contemplative dimension of Augustinian religious life.
Gregory was born around 1225 in Verucchio, Forli, Italy. As a young man, he joined the hermits of Blessed John Good, one of the groups that was incorporated into the Order of Saint Augustine at the time of the Grand Union in 1256.
He spent the greatest part of his life in contemplation, penance and asceticism at the Monte Carnerio hermitage, located near Fonto Colombo, Rieti.
He is said to have lived until 1343, which would mean that he was 118 years old at the time of his death. His remains are preserved in Verucchio.
