Over the centuries various devotional offices have been created, similar to the Divine Office, the official liturgy of the hours. These prayers, such as the Little Office of the Blessed Virgin Mary and the Office of the Passion, the latter composed by St. Francis of Assisi, have been used for particular purposes, such as expressing devotion to Mary or to the Passion of Christ.
One of the Franciscan Friars of the Immaculate has composed for the Knights of Lepanto a little devotional office called Knight’s Psalter. It expresses devotion to Our Lady of Victory and the spirit of Marian Chivalry. Here it is in PDF format.
