Mendicant order in the context of "Order of Saint Augustine"

The Discalced Carmelites, formally the Order of the Discalced Brothers of the Blessed Virgin Mary of Mount Carmel (Latin: Ordo Fratrum Carmelitarum Discalceatorum Beatae Mariae Virginis de Monte Carmelo) or the Order of Discalced Carmelites (Latin: Ordo Carmelitarum Discalceatorum; abbrev.: OCD; sometimes called in earlier times Latin: Ordo Carmelitarum Excalceatorum), is a mendicant order in the Roman Catholic Church with roots in the eremitic tradition of the Desert Fathers. The order was established in the 16th century, pursuant to the reform of the Carmelites of the Ancient Observance, by two Spanish saints, Teresa of Ávila and John of the Cross. Discalced is derived from Latin, meaning "without shoes".

The third order, which is affiliated to the Discalced Carmelites, is the Secular Order of Discalced Carmelites.

The Order of Preachers (Latin: Ordo Prædicatorum, abbreviated OP), commonly known as the Dominican Order, is a Catholic mendicant order of pontifical right that was founded in France by the Castilian priest Dominic de Guzmán. It was approved by Pope Honorius III via the papal bull Religiosam vitam on 22 December 1216. Members of the order, who are referred to as Dominicans, generally display the letters OP after their names, standing for Ordinis Praedicatorum, meaning 'of the Order of Preachers'. Membership in the order includes friars, nuns, active sisters, and lay or secular Dominicans (formerly known as tertiaries). More recently, there have been a growing number of associates of the religious sisters who are unrelated to the tertiaries.

Founded to preach the gospel and to oppose heresy, the teaching activity of the order and its scholastic organisation placed it at the forefront of the intellectual life of the Middle Ages. The order is famed for its intellectual tradition and for having produced many leading theologians and philosophers. In 2018, there were 5,747 Dominican friars, including 4,299 priests. The order is headed by the master of the order who, as of 2022, is Gerard Timoner III. The Blessed Virgin Mary, Mary Magdalene, Augustine of Hippo and Francis of Assisi are the Principal Patrons of the order.

The Royal, Celestial and Military Order of Our Lady of Mercy and the Redemption of the Captives (Latin: Ordo Beatae Mariae de Mercede Redemptionis Captivorum, abbreviated O. de M.), also known as the Mercedarians, is a Catholic mendicant order established in 1218 by Peter Nolasco in the city of Barcelona, at that time the capital of the Principality of Catalonia, part of the Crown of Aragon, for the redemption of Christian captives. Its members are most commonly known as Mercedarian friars or nuns. One of the distinguishing marks of the Order of the Blessed Virgin Mary of Mercy is that, since its foundation, its members are required to take a fourth vow: to die, if necessary, for another who is in danger of losing their faith. The Order exists today in 17 countries.

A priory is a monastery of men or women under religious vows that is headed by a prior or prioress. They are found in the Catholic Church, Lutheran Churches, and Anglican Communion. Priories may be monastic houses of monks or nuns (such as the Benedictines, the Cistercians, or the Charterhouses). Houses of canons & canonesses regular also use this term, the alternative being canonry. Mendicant houses, of friars, nuns, or tertiary sisters (such as the Friars Preachers, Augustinian Hermits, and Carmelites) also exclusively use this term.

In pre-Reformation England, if an abbey church was raised to cathedral status, the abbey became a cathedral priory. The bishop, in effect, took the place of the abbot, and the monastery itself was headed by a prior.

The Order of Discalced Augustinians (Latin: Ordo Augustiniensium Discalceatorum; abbreviation: OAD) is a mendicant order that branched off from the Order of Saint Augustine as a reform movement.

The Trinitarians, formally known as the Order of the Most Holy Trinity and of the Captives (Latin: Ordo Sanctissimae Trinitatis et Captivorum; abbreviated OSsT), is a mendicant order of the Catholic Church for men founded in Cerfroid, outside Paris, in the late 12th century. From the very outset, a special dedication to the mystery of the Holy Trinity has been a constitutive element of the order's life.

Papal documents refer to the founder only as "Brother John", but tradition identifies him as John of Matha, whose feast day is celebrated on 17 December. The founding-intention for the order was the ransom of Christians held captive by Muslims, a consequence of crusading and of piracy along the Mediterranean coast of Europe.

The Servite Order, officially known as the Order of Servants of Mary (Latin: Ordo Servorum Beatae Mariae Virginis; abbreviation: OSM), is one of the five original mendicant orders in the Roman Catholic Church. It includes several branches of friars (priests and brothers), contemplative nuns, a congregation of religious sisters, and lay groups. The order's objectives are the sanctification of its members, the preaching of the Gospel, and the propagation of devotion to the Mother of God, with special reference to her sorrows. The Servites friars lead a community life in the tradition of the mendicant orders.
