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.
For many denominations of Christianity, the writings of the Ante-Nicene Fathers, Nicene Fathers and Post-Nicene Fathers are included in Sacred Tradition. As such, in traditional dogmatic theology, authors considered Church Fathers are treated as authoritative for the establishment of doctrine. The academic field of patristics, the study of the Church Fathers, has extended the scope of the term, and there is no definitive list. Some, such as Origen and Tertullian, made major contributions to the development of later Christian theology, but certain elements of their teaching were later condemned.
Apostolic Fathers
The Apostolic Fathers were Christian theologians 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 popular in Early Christianity, were ultimately not included in the canon of the New Testament once it reached its final form. Many of the writings derive from the same time period and geographical location as other works of early Christian literature that did come to be part of the New Testament, and some of the writings found among the Apostolic Fathers' seem to have been just as highly regarded as some of the writings that became the New Testament. The first three, Clement, Ignatius, and Polycarp, are considered the chief ones.
Clement of Rome
Clement of Rome (also known as Pope Clement I) was a late 1st-century bishop of Rome who, according to Tertullian, was ordained by Saint Peter. According to Irenaeus, Clement was the fourth bishop of Rome after Anacletus. Eusebius described him as the "co-laborer" of Paul and identified him with the Clement mentioned in Philippians 4:3.
The First Epistle of Clement (c. 96) is the earliest extant epistle from a Church Father. In the epistle, Clement calls on the Christians of Corinth to maintain harmony and order. Copied and widely read in the Early Church, First Clement had been considered by some as part of the New Testament canon, e.g., listed as canonical in Canon 85 of the Canons of the Apostles, among other early canons of the New Testament, showing that it had canonical rank in at least some regions of early Christendom. As late as the 14th century Ibn Khaldun mentions it as part of the New Testament.
Ignatius of Antioch
Ignatius of Antioch (also known as Theophorus) (c. 35 – c. 110) was the third bishop of Antioch, and was said to be a student of the Apostle John. En route to his martyrdom in Rome, Ignatius wrote a series of letters which have been preserved. Important topics addressed in these letters include ecclesiology, the sacraments, the role of bishops, and the incarnation of Christ. He is the second after Clement to mention Paul's epistles.
Polycarp of Smyrna
Polycarp of Smyrna (c. 69 – c. 155) was a Christian bishop of Smyrna (now İzmir in Turkey). It is recorded that he had been a disciple of "John". The options/possibilities for this John are John, the son of Zebedee, traditionally viewed as the author of the Gospel of John, or John the Presbyter. Traditional advocates follow Eusebius of Caesarea in insisting that the apostolic connection of Polycarp was with John the Evangelist and that he was the author of the Gospel of John, and thus the Apostle John.
Polycarp tried and failed to persuade Pope Anicetus to have the West celebrate Passover on the 14th of Nisan, as in the Eastern calendar. Around AD 155, the Smyrnans of his town demanded Polycarp's execution as a Christian, and he died a martyr. The story of his martyrdom describes how the fire built around him would not burn him, and that when he was stabbed to death, so much blood issued from his body that it quenched the flames around him.
Papias of Hierapolis
Very little is known of Papias apart from what can be inferred from his own writings. He is described as "an ancient man who was a hearer of John and a companion of Polycarp" by Polycarp's disciple Irenaeus (c. 180). Eusebius adds that Papias was Bishop of Hierapolis around the time of Ignatius. In this office, Papias was presumably succeeded by Abercius of Hierapolis. The name Papias was very common in the region, suggesting that he was probably a native of the area. The work of Papias is dated by most modern scholars to about AD 95–120.
Despite indications that the work of Papias was still extant in the Late Middle Ages, the full text is now lost; however, extracts appear in a number of other writings, some of which cite a book number.
Greek Fathers
Those who wrote in Greek are called the Greek (Church) Fathers. In addition to the Apostolic Fathers, famous Greek Fathers include: Justin Martyr, Irenaeus of Lyons, Clement of Alexandria, Origen of Alexandria, Athanasius of Alexandria, the Cappadocian Fathers (Basil of Caesarea, Gregory Nazianzus, Gregory of Nyssa), Peter of Sebaste, Diodorus of Tarsus, Theodore of Mopsuestia, John Chrysostom, Cyril of Alexandria, Maximus the Confessor, and John of Damascus.
In the Catholic Church tradition, Athanasius of Alexandria (c. 296 or 298 – 373), Basil of Caesarea (c. 330 – 379), Gregory of Nazianzus (329 – c. 390), and John Chrysostom (347–407) are four Greek Church Fathers who are called the "Great Church Fathers", and in the Eastern Orthodox Church, three of these (Basil of Caesarea, Gregory of Nazianzus and John Chrysostom) are honored as the "Three Holy Hierarchs".
Justin Martyr
Justin Martyr was an early Christian apologist, and is regarded as the foremost interpreter of the theory of the Logos in the 2nd century. He was martyred, alongside some of his students, and is considered a saint by the Catholic Church, Oriental Orthodox Churches, the Eastern Orthodox Church, and Anglicanism.
Irenaeus of Lyons
Irenaeus was bishop of Lugdunum in Gaul, which is now Lyon(s), France. His writings were formative in the early development of Christian theology, and he is recognized as a saint by both the Eastern Orthodox Church and the Catholic Church. He was a notable early Christian apologist. He was also a disciple of Polycarp.
In his best-known book, Against Heresies (c. 180), he enumerated heresies and attacked them. Irenaeus wrote that the only way for Christians to retain unity was to humbly accept one doctrinal authority—episcopal councils. Irenaeus proposed that the Gospels of Matthew, Mark, Luke and John all be accepted as canonical.
Clement of Alexandria
Clement of Alexandria (c. 150–215) was the first member of the church of Alexandria whose writings have survived, and was one of its most distinguished teachers. He saw wisdom in Greek philosophy and sought to harmonize it with Christian doctrine. Clement opposed Gnosticism, and yet used some of its terminology; for instance, he valued gnosis that with communion for all people could be held by common Christians. He developed a Christian Platonism and has been described by scholars as "the founder of what was to become the great tradition of Christian philosophical theology." Due to his teaching on salvation and divine judgement in passages such as Paedagogus 1.8 and Stromata 7.2, Clement is often regarded as one of the first Christian universalists. Like Origen, he arose from the Catechetical School of Alexandria and was well-versed in pagan and biblical literature.
Origen of Alexandria
Origen, or Origen Adamantius (c. 185 – c. 254) was a scholar and theologian. According to tradition, he was an Egyptian who taught in Alexandria, reviving the Catechetical School where Clement had taught. The patriarch of Alexandria at first supported Origen but later expelled him for being ordained without the patriarch's permission. He relocated to Caesarea Maritima and died there after being tortured during a persecution. He later became a controversial figure and some of his writings were condemned as heretical.
Using his knowledge of Hebrew, he produced a corrected Septuagint. He wrote commentaries on all the books of the Bible. In Peri Archon (First Principles), he articulated a systematic philosophical exposition of Christian doctrine. He at times employed an allegorical hermeneutic in his interpretation of the Old Testament, and was partly influenced by Stoic, Neo-Pythagorean, and Platonist thought. Like Plotinus, he has been thought to believe that the soul passes through successive stages before incarnation as a human and after death, eventually reaching God. However, more recent scholarship has concluded that Origen actually denied the preexistence of disembodied souls, and simply taught the preexistence of individuals' logoi in the mind of God. Yet Origen did suggest, based on 1 Corinthians 15:22–28, that all creatures, possibly including even the fallen angels, will eventually be restored and reunited to God when evil is finally eradicated. For Origen, God was the First Principle, and Christ, the Logos through whom salvation is accomplished. Origen's various writings were interpreted by some to imply a hierarchical structure in the Trinity, the temporality of matter, "the fabulous preexistence of souls", and "the monstrous restoration which follows from it." These alleged "Origenist errors" were declared anathema by a council in 553, three centuries after Origen had died in the peace of the church.
Athanasius of Alexandria
Athanasius of Alexandria (c. 293 – 373) was a theologian, Pope of Alexandria, and a noted Egyptian leader of the 4th century. He is remembered for his role in the conflict with Arianism and for his affirmation of the Trinity. At the First Council of Nicaea (325), Athanasius argued against the Arian doctrine that Christ is of a distinct substance from the Father.
Cappadocian Fathers
The Cappadocian Fathers are Basil the Great (330–379), who was bishop of Caesarea; Basil's younger brother Gregory of Nyssa (c. 332 – 395), who was bishop of Nyssa; and a close friend, Gregory of Nazianzus (329–389), who became Patriarch of Constantinople. The Cappadocians promoted early Christian theology and are highly respected in both Western and Eastern churches as saints. They were a 4th-century monastic family, led by Macrina the Younger (324–379) to provide a central place for her brothers to study and meditate, and also to provide a peaceful shelter for their mother. Abbess Macrina fostered the education and development of her three brothers Basil the Great, Gregory of Nyssa and Peter of Sebaste (c. 340 – 391) who became bishop of Sebaste.
These scholars set out to demonstrate that Christians could hold their own in conversations with learned Greek-speaking intellectuals. They argued that Christian faith, while it was against many of the ideas of Plato and Aristotle (and other Greek philosophers), was an almost scientific and distinctive movement with the healing of the soul of man and his union with God at its center. They made major contributions to the definition of the Trinity finalized at the First Council of Constantinople in 381 and the final version of the Nicene Creed.
Subsequent to the First Council of Nicea, Arianism did not simply disappear. The semi-Arians taught that the Son is of like substance with the Father (homoiousios), as against the outright Arians who taught that the Son was unlike the Father (heterousian). So the Son was held to be like the Father but not of the same essence as the Father.
The Cappadocians worked to bring these semi-Arians back to the Orthodox cause. In their writings they made extensive use of the formula "three substances (hypostases) in one essence (homoousia)", and thus explicitly acknowledged a distinction between the Father and the Son (a distinction that Nicea had been accused of blurring) but at the same time insisting on their essential unity.
John Chrysostom
John Chrysostom (c. 347 – c. 407), archbishop of Constantinople, is known for his eloquence in preaching and public speaking; his denunciation of abuse of authority by both ecclesiastical and political leaders, recorded sermons and writings making him the most prolific of the eastern fathers, and his ascetic sensibilities. After his death (or according to some sources, during his life) he was given the Greek epithet chrysostomos, meaning "golden mouthed", rendered in English as Chrysostom.
Chrysostom is known within Christianity chiefly as a preacher and theologian, particularly in the Eastern Orthodox Church; he is the patron saint of orators in the Catholic Church. Chrysostom is also noted for eight of his sermons that played a considerable part in the history of Christian antisemitism, diatribes against Judaizers composed while a presbyter in Antioch, which were extensively exploited and misused by the Nazis in their ideological campaign against the Jews. Patristic scholars such as Robert L Wilken point out that applying modern understandings of antisemitism back to Chrysostom is anachronistic due to his use of the Psogos. The Psogos, along with the encomium, were both rhetorical techniques used in the ancient world in a polemical context. With the encomium "one passes over a man's faults in order to praise him, and in a psogos, one passed over his virtues to defame him. Such principles are explicit in the handbooks of the rhetors, but an interesting passage from the church historian Socrates, writing in the mid-fifth century, shows that the rules for invective were simply taken for granted by men and women of the late Roman world."
Chrysostom's sermons along with Basil the Great's have greatly influenced the Christian Church's understanding of economic and distributive justice for the poor, being cited extensively by the Catechism of the Catholic Church as well as Pope Francis in his own sermons critiquing modern-day forms of capitalism.
Theodore of Mopsuestia
Theodore of Mopsuestia (c. 350 – 428) was a Christian theologian, and Bishop of Mopsuestia (as Theodore II) from 392 to 428 AD. He is also known as Theodore of Antioch, from the place of his birth and presbyterate. He is the best known representative of the middle Antioch School of hermeneutics. He is known to be a prolific writer and exegete with strong emphases on the literal, historical and rational interpretation of Christian scriptures. Throughout his lifetime, he was hailed as one of the outstanding, prolific biblical theologians and staunch defender of Christ's humanity. More than a century after his death, he was condemned in person in the Chalcedonian Church at the Second Council of Constantinople. However he continues to be recognised as a Greek Doctor in the Church of the East, which honours him with the title 'Theodore the Interpreter'.
In 394, he attended a synod at Constantinople on a question which concerned the see of Bostra in the patriarchate of Antioch. While there, Theodore had the opportunity to preach before the emperor Theodosius I, who was then starting for his last journey to the West. The sermon made a deep impression, and Theodosius, who had sat at the feet of Ambrose and Gregory Nazianzus, declared that he had never met with such a teacher (John of Antioch, ap. Facund. ii.2). Theodosius II inherited his grandfather's respect for Theodore, and often wrote to him. Another glimpse of Theodore's episcopal life is supplied by a letter of Chrysostom to him from Cucusus (AD 404–407) (Chrys. Ep. 212). The exiled patriarch "can never forget the love of Theodore, so genuine and warm, so sincere and guileless, a love maintained from early years, and manifested but now." Chrysostom (Ep. 204) thanks him profoundly for frequent though ineffectual efforts to obtain his release, and praises their friendship in such glowing terms that Theodore's enemies at the fifth Ecumenical Council made unsuccessful efforts to deny the identity of Chrysostom's correspondent with the bishop of Mopsuestia.
Cyril of Alexandria
Cyril of Alexandria (c. 378 – 444) was the Bishop of Alexandria when the city was at its height of influence and power within the Roman Empire. Cyril wrote extensively and was a leading protagonist in the Christological controversies of the late 4th and early 5th centuries. He was a central figure in the First Council of Ephesus in 431, which led to the deposition of Nestorius as Archbishop of Constantinople. Cyril's reputation within the Christian world has resulted in his titles "Pillar of Faith" and "Seal of all the Fathers".
Maximus the Confessor
Maximus the Confessor (also known as Maximus the Theologian and Maximus of Constantinople) (c. 580 – 662) was a Christian monk, theologian, and scholar. In his early life, he was a court secretary to the Byzantine Emperor Heraclius; however, he gave up this life in the political sphere to enter into the monastic life.
After moving to Carthage, Maximus studied several Neo-Platonist writers and became a prominent author. When one of his friends began espousing the Christological position known as Monothelitism, Maximus was drawn into the controversy, in which he supported the Chalcedonian position that Jesus had both a human and a divine will. Maximus is venerated in both Eastern Christianity and Western Christianity. His Christological positions eventually resulted in his torture and exile, soon after which he died; however, his theology was vindicated by the Third Council of Constantinople, and he was venerated as a saint soon after his death. His feast day is celebrated twice during the year: on 21 January and on 13 August. His title of Confessor means that he suffered for the faith, but not to the point of death, and thus is distinguished from a martyr. His Life of the Virgin is thought to be the earliest complete biography of Mary, the mother of Jesus.
John of Damascus
John of Damascus (c. 676 – 749) was a Syrian Christian monk, priest, hymnographer and apologist. Born and raised in Damascus, he died at his monastery, Mar Saba, near Jerusalem.
A polymath whose fields of interest and contribution included law, theology, philosophy, and music, he was given the by-name of Chrysorrhoas (Χρυσορρόας, literally "streaming with gold", i.e. "the golden speaker"). He wrote numerous works expounding the Christian faith, and composed hymns which are still used both liturgically in Eastern Christian practice throughout the world as well as in western Lutheranism at Easter. He was particularly known for his defense of icons.
The Catholic Church regards him as a Doctor of the Church, often referred to as the Doctor of the Assumption because of his writings on the Assumption of Mary.
Latin Fathers
Those fathers who wrote in Latin are called the Latin (Church) Fathers. In the Catholic Church tradition, Ambrose (AD 340–397), Jerome (347–420), Augustine of Hippo (354–430), and Pope Gregory I (540–604) are four Latin Church Fathers who are called the "Great Church Fathers".
Tertullian
Quintus Septimius Florens Tertullianus (c. 155 – c. 222), who was converted to Christianity before 197, was a prolific writer of apologetic, theological, controversial and ascetic works. He was born in Carthage, the son of a Roman centurion.
Tertullian denounced Christian doctrines he considered heretical, such as allowing widows to remarry and permitting Christians to flee from persecution, but later in life adopted Montanism, regarded as heretical by the mainstream Church, which prevented his canonization. He wrote three books in Greek and was the first great writer of Latin Christianity, thus sometimes known as the "Father of the Latin Church". He was evidently a lawyer in Rome. He is said to have introduced the Latin term trinitas with regard to the Divine (Trinity) to the Christian vocabulary (but Theophilus of Antioch had already written of "the Trinity, of God, and His Word, and His Wisdom", which is similar but not identical to the Trinitarian wording), and also probably the formula "three Persons, one Substance" as the Latin "tres Personae, una Substantia" (itself from the Koine Greek "τρεῖς ὑποστάσεις, ὁμοούσιος; treís hypostasis, Homoousios"), and also the terms vetus testamentum (Old Testament) and novum testamentum (New Testament).
In his Apologeticus, he was the first Latin author who qualified Christianity as the vera religio, and systematically relegated the classical Roman imperial religion and other accepted cults to the position of mere "superstitions".
He used the early church's symbol for fish—the Greek word for "fish" being ΙΧΘΥΣ, which is an acronym for Ἰησοῦς Χριστός, Θεοῦ Υἱός, Σωτήρ (Jesus Christ, God's Son, Saviour)—to explain the meaning of baptism, since fish are born in water. He wrote that human beings are like little fish.
Cyprian of Carthage
Cyprian (c. 200 – 258) was bishop of Carthage and an important early Christian writer. He was born in North Africa, probably at the beginning of the 3rd century, perhaps at Carthage, where he received an excellent classical (pagan) education. After converting to Christianity, he became a bishop and eventually died a martyr at Carthage. He emphasized the necessity of the unity of Christians with their bishops, and also the authority of the Roman See, which he claimed was the source of "priestly unity"'.
