Order of Saint Augustine in the context of "Catholic religious order"

Pope Leo XIV (born Robert Francis Prevost, September 14, 1955) is the head of the Catholic Church and sovereign of Vatican City. He is the first pope to have been born in the United States, the first to hold either U.S. or Peruvian citizenships, the first from the Order of Saint Augustine, and the second (after his immediate predecessor Pope Francis) from the Americas.

Prevost was born in Chicago and raised in the nearby suburb of Dolton, Illinois. He became a friar in the Order of Saint Augustine in 1977 and was ordained as a priest in 1982. He earned a Doctor of Canon Law (JCD) degree in 1987 from the Pontifical University of Saint Thomas Aquinas in Rome. His service includes extensive missionary work in Peru in the 1980s and 1990s—he worked there as a parish pastor, diocesan official, seminary teacher, and administrator. Elected prior general of the Order of Saint Augustine, he was based in Rome from 2001 to 2013, and traveled extensively as part of this work, including to the order's many provinces and missions around the world. He then returned to Peru as Bishop of Chiclayo from 2015 to 2023. In 2023, Pope Francis appointed him prefect of the Dicastery for Bishops in Rome, and president of the Pontifical Commission for Latin America.

Augustinians are members of several religious orders that follow the Rule of Saint Augustine, written about 400 A.D. by Augustine of Hippo. There are two distinct types of Augustinians in Catholic religious orders dating back to the 12th–13th centuries:

• Various congregations of Canons Regular follow the Rule of Saint Augustine, embracing the evangelical counsels and leading a semi-monastic life, while remaining committed to pastoral care appropriate to their primary vocation as priests. They generally form one large community which might serve parishes in the vicinity, and are organized into autonomous congregations.
• Several orders of friars who live a mixed religious life of contemplation and apostolic ministry. The largest and most familiar is the Order of Saint Augustine (O.S.A.), founded in 1244 and originally known as the Hermits of Saint Augustine (O.E.S.A.). They are commonly known as the Austin Friars in England. Two other orders, the Order of Augustinian Recollects (O.A.R.) and the Discalced Augustinians (O.A.D.), were once part of the original Order under a single Prior General. The Recollects, begun in 1588 as a reform movement in Spain to recover the Order's eremitical roots, became autonomous in 1612. At the 100th General Chapter of the Order held in Rome in May 1592, those seeking reform of their way of life came to be called the Discalced (barefoot) and were authorized to seek their goals as an semi-independent branch. They were raised to the status of a separate mendicant Order in 1610.

There are also some Anglican religious orders created in the 19th century that follow Augustine's rule. These are composed only of women in several different communities of Augustinian nuns.

Martin Luther (/ˈluːθər/ LOO-thər; German: [ˈmaʁtiːn ˈlʊtɐ] ; 10 November 1483 – 18 February 1546) was a German priest, theologian, author, hymnwriter, professor, and former Augustinian friar. Luther was the seminal figure of the Protestant Reformation, and his theological beliefs form the basis of Lutheranism. He is widely regarded as one of the most influential figures in Western and Christian history.

Born in Eisleben, Luther was ordained to the priesthood in 1507. He came to reject several teachings and practices of the contemporary Roman Catholic Church, in particular the view on indulgences and papal authority. Luther initiated an international debate on these in works like his Ninety-five Theses, which he authored in 1517. In 1520 Pope Leo X demanded that Luther renounce all of his writings, and when Luther refused to do so, excommunicated him in January 1521. Later that year, Holy Roman Emperor Charles V condemned Luther as an outlaw at the Diet of Worms. When Luther died in 1546, his excommunication by Leo X was still in effect.

Gregor Johann Mendel OSA (/ˈmɛndəl/; German: [ˈmɛndl̩]; Czech: Řehoř Jan Mendel; 20 July 1822 – 6 January 1884) was an Austrian biologist, meteorologist, mathematician, Augustinian friar and abbot of St. Thomas' Abbey in Brno (Brünn), Margraviate of Moravia. Mendel was born in a German-speaking family in the Silesian part of the Austrian Empire (today's Czech Republic) and gained posthumous recognition as the founder of the modern science of genetics. Though farmers had known for millennia that crossbreeding of animals and plants could favor certain desirable traits, Mendel's pea plant experiments conducted between 1856 and 1863 established many of the rules of heredity, now referred to as the laws of Mendelian inheritance.

Mendel worked with seven characteristics of pea plants: plant height, pod shape and color, seed shape and color, and flower position and color. Taking seed color as an example, Mendel showed that when a true-breeding yellow pea and a true-breeding green pea were cross-bred, their offspring always produced yellow seeds. However, in the next generation, the green peas reappeared at a ratio of 1 green to 3 yellow. To explain this phenomenon, Mendel coined the terms "recessive" and "dominant" in reference to certain traits. In the preceding example, the green trait, which seems to have vanished in the first filial generation, is recessive, and the yellow is dominant. He published his work in 1866, demonstrating the actions of invisible "factors"—now called genes—in predictably determining the traits of an organism. The actual genes were only discovered in a long process that ended in 2025 when the last three of the seven Mendel genes were identified in the pea genome.

El Escorial, or the Royal Site of San Lorenzo de El Escorial (Spanish: Monasterio y Sitio de El Escorial en Madrid), or Monasterio de El Escorial (Spanish pronunciation: [el eskoˈɾjal]), is a historical residence of the king of Spain located in the town of San Lorenzo de El Escorial, 2.06 kilometres (1.28 mi) up the valley (4.1 km [2.5 mi] road distance) from the town of El Escorial and about 45 kilometres (28 mi) northwest of the Spanish capital Madrid. Built between 1563 and 1584 by order of King Philip II (who reigned 1556–1598), El Escorial is the largest Renaissance building in the world. It is one of the Spanish royal sites and functions as a monastery, basilica, royal palace, pantheon, library, museum, university, school, and hospital.

El Escorial consists of two architectural complexes of great historical and cultural significance: the royal monastery itself and La Granjilla de La Fresneda, a royal hunting lodge and monastic retreat about five kilometres (3.1 mi) away. These sites have a dual nature: during the 16th and 17th centuries, they were places in which the power of the Spanish monarchy and the ecclesiastical predominance of the Roman Catholic religion in Spain found a common architectural manifestation. El Escorial was both a Spanish royal palace and a monastery. Established with a community of Hieronymite monks, it has become a monastery of the Order of Saint Augustine. It also contained a boarding school, now the Real Colegio de Alfonso XII, still in operation.

Luis de León OESA (Belmonte, Cuenca, 1527 – Madrigal de las Altas Torres, Castile, Spain, 23 August 1591), was a Spanish lyric poet, Augustinian friar, theologian and academic.

While serving as professor of Biblical scholarship at the University of Salamanca, Fray Luis also wrote many immortal works of Spanish Christian poetry and translated both Biblical Hebrew poetry and Latin Christian poetry into the Spanish language. Despite being a devout and believing Roman Catholic priest, Fray Luis was descended from a family of Spanish Jewish Conversos and this, as well as his vocal advocacy for teaching the Hebrew language in Catholic universities and seminaries, drew false accusations from the Dominican Order of the heresies of being both a Marrano and a Judaiser. Fray Luis was accordingly imprisoned for four years by the Spanish Inquisition before he was ruled to be completely innocent of any wrongdoing and released without charge. While the conditions of his imprisonment were never harsh and he was allowed complete access to books, according to legend, Fray Luis started his first post-Inquisition University of Salamanca lecture with the words, "As I was saying the other day..."
