Augustine of Hippo, also known as Saint Augustine, was a theologian and philosopher of Berber origin and the bishop of Hippo Regius in Numidia, Roman North Africa. His writings 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.
Athanasius I of Alexandria, also called Athanasius the Great, Athanasius the Confessor, or, among Coptic Christians, Athanasius the Apostolic, was a Christian theologian and the 20th patriarch of Alexandria. His intermittent episcopacy spanned 45 years, of which over 17 encompassed five exiles, when he was replaced on the order of four different Roman emperors. Athanasius was a Church Father, the chief defender of Trinitarianism against Arianism, and a noted Egyptian Christian leader of the fourth century.
Eusebius of Caesarea, also known as Eusebius Pamphilus, was a Greek Syro-Palestinian historian of Christianity, exegete, and Christian polemicist. In about AD 314 he became the bishop of Caesarea Maritima in the Roman province of Syria Palaestina. Together with Pamphilus, he was a scholar of the biblical canon and is regarded as one of the most learned Christians during late antiquity. He wrote Demonstrations of the Gospel, Preparations for the Gospel and On Discrepancies between the Gospels, studies of the biblical text. As "Father of Church History", he produced the Ecclesiastical History, On the Life of Pamphilus, the Chronicle and On the Martyrs. He also produced a biographical work on Constantine the Great, the first Christian Roman emperor, who was Augustus between AD 306 and AD 337.
Irenaeus was a Greek bishop noted for his role in guiding and expanding Christian communities in the southern regions of present-day France and, more widely, for the development of Christian theology by combating heterodox or Gnostic interpretations of Scripture as heresy and defining proto-orthodoxy. Originating from Smyrna, he had seen and heard the preaching of Polycarp, who in turn was said to have heard John the Evangelist, and thus was the last-known living connection with the Apostles.
Jerome, also known as Jerome of Stridon, was an early Christian priest, confessor, theologian, translator, and historian; he is commonly known as Saint Jerome.
John Chrysostom was an important Early Church Father who served as archbishop of Constantinople. He is known for his preaching and public speaking, his denunciation of abuse of authority by both ecclesiastical and political leaders, his Divine Liturgy of Saint John Chrysostom, and his ascetic sensibilities. The epithet Χρυσόστομος means "golden-mouthed" in Greek and denotes his celebrated eloquence. Chrysostom was among the most prolific authors in the early Christian Church.
The Ante-Nicene Fathers, subtitled "The Writings of the Fathers Down to A.D. 325" and abbreviated as ANF, is a collection of books in 10 volumes containing English translations of the majority of Early Christian writings. The period covers the beginning of Christianity until the promulgation of the Nicene Creed at the First Council of Nicaea.
Pope Leo I, also known as Leo the Great, was Bishop of Rome from 29 September 440 until his death.
Clement of Rome, also known as Pope Clement I, was the bishop of Rome in the late first century AD. He is listed by Irenaeus and Tertullian as the bishop of Rome, holding office from 88 AD to his death in 99 AD. He is considered to be the first Apostolic Father of the Church, one of the three chief ones together with Polycarp and Ignatius of Antioch.
Basil of Caesarea, also called Saint Basil the Great, was a bishop of Caesarea Mazaca in Cappadocia, Asia Minor. He was an influential theologian who supported the Nicene Creed and opposed the heresies of the early Christian church, fighting against both Arianism and the followers of Apollinaris of Laodicea. His ability to balance his theological convictions with his political connections made Basil a powerful advocate for the Nicene position.
Pelagius was a Romano-British theologian known for promoting a system of doctrines which emphasized human choice in salvation and denied original sin. Pelagius was accused of heresy at the synod of Jerusalem in 415 and his doctrines were harshly criticized by Augustine of Hippo, especially the Pelagian views about mankind's good nature and individual responsibility for choosing asceticism. Pelagius especially stressed the freedom of human will. Very little is known about the personal life and career of Pelagius.
The Epistle of Barnabas is a Greek epistle written between AD 70 and 132. The complete text is preserved in the 4th-century Codex Sinaiticus, where it appears immediately after the New Testament and before the Shepherd of Hermas. For several centuries it was one of the "antilegomena" ("disputed") writings that some Christians looked on as sacred scripture, while others excluded them. Eusebius of Caesarea classified it with excluded texts. It is mentioned in a perhaps third-century list in the sixth-century Codex Claromontanus and in the later Stichometry of Nicephorus appended to the ninth-century Chronography of Nikephoros I of Constantinople. Some early Fathers of the Church ascribed it to the Barnabas who is mentioned in the Acts of the Apostles, but it is now generally attributed to an otherwise unknown early Christian teacher, although some scholars do defend the traditional attribution. It is distinct from the Gospel of Barnabas.
Marcionism was an early Christian dualistic belief system that originated with the teachings of Marcion of Sinope in Rome around the year 144. Marcion was an early Christian theologian, evangelist, and an important figure in early Christianity. He was the son of a bishop of Sinope in Pontus. About the middle of the 2nd century (140–155) he traveled to Rome, where he joined the Syrian Gnostic Cerdo.
The Apostolic Fathers, also known as the Ante-Nicene Fathers, were core Christian theologians among the Church Fathers who lived in the 1st and 2nd centuries AD who are believed to have personally known some of the Twelve Apostles or to have been significantly influenced by them. Their writings, though widely circulated in early Christianity, were not included in the canon of the New Testament. Many of the writings derive from the same time period and geographical location as other works of early Christian literature which came to be part of the New Testament.
The New Testament apocrypha are a number of writings by early Christians that give accounts of Jesus and his teachings, the nature of God, or the teachings of his apostles and of their lives. Some of these writings were cited as scripture by early Christians, but since the fifth century a widespread consensus has emerged limiting the New Testament to the 27 books of the modern canon. Roman Catholic, Eastern Orthodox, and Protestant churches generally do not view the New Testament apocrypha as part of the Bible.
A homiliarium or homiliary is a collection of homilies, or familiar explanations of the Gospels.
The Church Fathers, Early Church Fathers, Christian Fathers, or Fathers of the Church were ancient and influential Christian theologians and writers who established the intellectual and doctrinal foundations of Christianity. The historical period in which they worked became known as the Patristic Era and spans approximately from the late 1st to mid-8th centuries, flourishing in particular during the 4th and 5th centuries, when Christianity was in the process of establishing itself as the state church of the Roman Empire.
The Eastern Orthodox Church is opposed to the Roman Catholic doctrine of papal supremacy. While not denying that primacy does exist for the Bishop of Rome, Eastern Orthodox Christians argue that the tradition of Rome's primacy in the early Church was not equivalent to the current doctrine of supremacy.
Augustinian Calvinism is a term used to emphasize the origin of John Calvin's theology within Augustine of Hippo's theology over a thousand years earlier. By his own admission, John Calvin's theology was deeply influenced by Augustine of Hippo, the fourth-century church father. Twentieth-century Reformed theologian B. B. Warfield said, "The system of doctrine taught by Calvin is just the Augustinianism common to the whole body of the Reformers." Paul Helm, a well-known Reformed theologian, used the term "Augustinian Calvinism" for his view in the article "The Augustinian-Calvinist View" in Divine Foreknowledge: Four Views.
Ancient Christian Writers: the works of the Fathers in translation is a book series with English translations of works by early Christian writers. The translations are made from Latin and Greek.
