Augustine of Hippo

Augustine of Hippo (/ɔːˈɡʌstɪn/ aw-GUST-in, US also /ˈɔːɡəstiːn/ AW-gə-steen; Latin: Aurelius Augustinus Hipponensis; 13 November 354 – 28 August 430) was a theologian and philosopher, the bishop of Hippo Regius from Thagaste in Numidia Cirtensis, (present-day Souk Ahras, Algeria). His writings deeply influenced the development of Western philosophy and Western Christianity, and he is viewed as one of the most important Church Fathers of the Latin Church in the Patristic Period. His many important works include The City of God, On Christian Doctrine, and Confessions.

According to his contemporary, Jerome of Stridon, Augustine "established anew the ancient Faith". In his youth he was drawn to the Manichaean faith, and later to the Hellenistic philosophy of Neoplatonism. After his conversion to Christianity and baptism in 386, Augustine developed his own approach to philosophy and theology, accommodating a variety of methods and perspectives. Believing the grace of Christ was indispensable to human freedom, he helped formulate the doctrine of original sin and made significant contributions to the development of just war theory. When the Western Roman Empire began to disintegrate, Augustine imagined the Church as a spiritual City of God, distinct from the material Earthly City. The segment of the Church that adhered to the concept of the Trinity as defined by the Council of Nicaea and the Council of Constantinople closely identified with Augustine's On the Trinity.

Augustine is recognized as a saint in the Catholic Church, the Eastern Orthodox Church, the Lutheran churches, and the Anglican Communion. He is also a preeminent Catholic Doctor of the Church and the patron of the Augustinians. His memorial is celebrated on 28 August, the day of his death. Augustine is the patron saint of brewers, printers, theologians, and a number of cities and dioceses. His thoughts profoundly influenced the medieval worldview. Many Protestants, especially Calvinists and Lutherans, consider him one of the theological fathers of the Protestant Reformation due to his teachings on salvation and divine grace. Protestant Reformers generally, and Martin Luther in particular, held Augustine in preeminence among early Church Fathers. From 1505 to 1521, Luther was a member of the Order of the Augustinian Eremites.

In the East, his teachings are more disputed. The most controversial doctrine associated with him, the filioque, was rejected by the Eastern Orthodox Church. Other disputed teachings include his views on original sin, the doctrine of grace, and predestination. Though considered to be mistaken on some points, he is still considered a saint and has influenced some Eastern Church Fathers, most notably Gregory Palamas. In the Greek and Russian Orthodox Churches, his feast day is celebrated on 15 June. Among modern Eastern Orthodox theologians, his views were notably attacked by John Romanides, but others have shown significant approbation, chiefly Georges Florovsky.

Augustine of Hippo, also known as Saint Augustine or Saint Austin, is known by various cognomens throughout the many denominations of the Christian world, including Blessed Augustine and the Doctor of Grace (Latin: Doctor gratiae).

Augustine was born in 354 in the municipium of Thagaste (now Souk Ahras, Algeria) in the Roman province of Numidia. His mother, Monica or Monnica, was a devout Christian; his father Patricius was a pagan who converted to Christianity on his deathbed. He had a brother named Navigius and a sister whose name is lost but is conventionally remembered as Perpetua.

Scholars generally agree that Augustine and his family were Berbers, an ethnic group indigenous to North Africa, but were heavily Romanized, speaking only Latin at home as a matter of pride and dignity. In his writings, Augustine mentions in passing his identity as a Roman African. For example, he refers to Apuleius as "the most notorious of us Africans," to Ponticianus as "a country man of ours, insofar as being African," and to Faustus of Mileve as "an African Gentleman".

Augustine's family name, Aurelius, suggests his father's ancestors were freedmen of the gens Aurelia given full Roman citizenship by the Edict of Caracalla in 212. Augustine's family had been Roman, from a legal standpoint, for at least a century when he was born. It is assumed that his mother, Monica, was of Berber origin, on the basis of her name, but as his family were honestiores, an upper class of citizens known as honorable men, Augustine's first language was likely Latin.
