The early years in the order's history featured a great devotion to learning, to study, to prayer, to service of the poor, and to defense of the Pope and the Church – a particular charism of the Order rooted in the fact that it is the only Order in the history of the Church to be founded directly by a Pope. In his work "The Life of the Brothers", the 14th-century Augustinian historian and friar Jordan of Saxony writes:"It is certain that in its modern state the Order is principally founded on spiritual works, those that pertain to the contemplative life. These are as follows: the singing of the divine office; the service of the altar; prayer; psalm singing; devotion to reading or study of sacred scripture; teaching and preaching the word of God; hearing confessions of the faithful; bringing about the salvation of souls by word and example."
