A Primer on the Church Fathers by Joe Gallegos

"Remove not the ancient landmark which your fathers have set"(Prov. 22:28 RSV)

Protestant Evangelical Christians often gain a keener understanding of Holy Writ either by a private reading of Scripture or by listening to or reading various interpretations of Scripture through various ministrations of the church such as a Bible study or a Sunday sermon. Many of the interpretations are harmonious with the historic tenants of the Holy Catholic Apostolic Church and some contradictory. Nevertheless, this is the primary vehicle through which many Evangelicals learn Christian doctrines and morals. Therefore, why not take advantage of a Bible study or a sermon by listening to the written words of a disciple of an Apostle or their immediate descendants rather than from someone who is 20 centuries removed from the Apostles? This is the case when one delves in the writings and faith of the early Church Fathers.

Who are these guys(and gals) called The Church Fathers?

The Church Fathers is a titled bestowed on men (and some women such as Egeria of Spain fl AD 448) in the ancient Church that are united by four trademarks: (1) a rigid orthodoxy in doctrine, (2) an exemplary holy life, (3) approval in the Church, and (4) antiquity. Today, some ecclesiastical writers are bestowed this title who have partially fulfilled these marks( e.g. Tertullian, Origen and Eusebius of Caesarea). These writers are included due to their invaluable service to the Church. The majority of the Church Fathers were bishops, a few held a lower clerical rank such as St. Jerome, and fewer yet, were laymen such as Clement of Alexandria and perhaps Tertullian of Carthage. In the Catholic Church the period of antiquity ends with St. John Damascene (d AD 749) in the East and with St. Gregory the Great(d AD 604) or St. Isidore of Seville (d AD 636) in the West, hence the patristic age spans 7 centuries.

St. Epiphanius provides us with this classic understanding of Church Father, he writes:

"Now of these which is wiser? This deceived man (Aerius) who has just now obtained notoriety, and who is still living; or they who were witnesses before us, who held before us the tradition in(or for) the church, and who themselves had received it from their fathers, whose fathers again had learnt it from their forefathers, even as the church, having received the true faith from its fathers, retains it, together with the traditions, even unto this day."
Epiphanius,Panarion, 75(A.D. 374-377),in FOC,I:433-434

The Fathers' writings

The writings of the Church Fathers took various forms. Their writings included sermons on various matters of faith (e.g. St. Augustine's sermons), treatises on various theological subjects (e.g. Cyprian's Unity of the Catholic Church), biographies (e.g. St. Possidius' Life of Augustine), autobiographies (e.g. St. Augustine's Confessions), hagiographies (e.g. St. Athanasius' Life of St. Antony), letters (e.g. St. Ambrose's 91 epistles), histories (e.g. Eusebius' Ecclesiastical History), exegetical works (e.g. Origen's & St. John Chrysostom's commentaries), patristic studies (e.g. St. Jerome's Lives of illustrious men), and apologies (e.g. St. Justin Martyr's' Apologies). Some ancient writings have no ascribed author such as the Didache or the Epistle to Diognetus. Some writings have an ascribed pseudo-author such as the Athanasian Creed or the New Testament apocryphal works. Some writings we have only in fragments(Muratorian fragment) and many writings are not extant(the majority of Origen's efforts) but are known through the writings of others.

Classifying the Fathers

There are a couple of ways of classifying the writings of the Church Fathers. The most popular way is to divide the writings into various periods of time. The other approach is to divide the Fathers by geography and culture, that is, East versus West. This first method usually divides the Fathers into three basic time periods: 1) the Ante-Nicene period (post Apostolic times until AD 325), 2) the Post-Nicene Fathers (AD 325 - AD 451), and 3) the later Fathers (AD 451 until the close of the Patristic age AD 749). Another popular way of dividing the Fathers into time periods is: 1) the period of Origins which include the Apostolic Fathers and the Apologists (post Apostolic times until AD 300), 2) the Classical or Golden Period (AD 300 to the death of Cyril of Alexandria d. AD 444), and 3)the Last period sometimes called the decadent period (AD 444 - to the close of the Patristic Age AD 749). There are some small variations to these time periods in various patrologies and studies. The second method is to divide the Fathers into two groups, the Western/Latin and the Eastern/Greek. However, not all the Fathers can be classified as either representing the West or the East such as the Coptic, Syriac, Arabic and Iberian Fathers. There are seven(7) centuries of patristic heritage involving diverse languages, cultures, and geography. This alone assured the Catholic Church a diversity of patristic thought on a myriad of theological subjects. The Fathers taken as a whole touched on every conceivable tenant of faith, taken individually, no one Father wrote on every doctrine. Time and circumstance provided the impetus for the various subjects and efforts treated by the Church Fathers. St. Irenaeus and Tertullian wrote extensively on the rule of faith against the criticisms of the numerous Gnostic heresies, St. Athanasius debated and routed the Arians on the deity of Jesus Christ, Cyprian wrote on the episcopacy in many of his treatises, St. Basil delved into the deity of the Holy Spirit in his conflicts with Eunomious, St. Jerome translated the Bible into Latin at the request of Pope Damasus, the Cappadocians (St. Basil, Gregory of Nyssa, & Gregory of Nazianzen) wrote and expounded on the mystery of the Holy Trinity, and St. Augustine expounded on grace, free-will, sin, and ecclesiology in his controversies with the Manicheans, Donatists, and Pelagians. No Church Father wrote on every Catholic doctrine. The Fathers taken as a whole provide us with an unswerving consensus and testimony of the Catholic faith.


In addition to the language, cultural, and geographic differences, there were numerous theological conflicts which shaped theology throughout the patristic age. Some conflicts came outside the Church such as Judaism, Gnosticism and Manichaeism. However, most of the conflicts came from within the Church. Some internal conflicts dealt with heretical teachings such as Arianism, Monophystism, Nestorianism, and Pelagianism. All these heresies were combated by the Church Fathers in the form of apologies, treatises, debates, and letters. The definitive reply to many of these early heresies came within the acts and canons of the Ecumenical Councils or through the proclamations of various Apostolic Sees, primarily the See of Rome. Some internal conflicts involved only the orthodox, such as the dating of Easter or episode concerning the lapse Christians and heretical baptism.

Consensus and Development of Doctrine

Amongst this diversity of patristic thought the Fathers were united on a number of doctrines without much controversy or discussion. Some of these doctrines include: 1) the existence of One God, 2) sotierology and sacraments, 3) ecclesiastical authority, 4) the existence of heaven and hell, 5)the existence of an invisible world consisting of angels and demons, 6) regenerative water baptism, and 7) the real presence in the Eucharist. However, many of the doctrines of today such as the Holy Trinity were a result of many years of reflection, dialogue and debate. In fact, prior to formal definition many of the Fathers would seem to have downplayed various aspects of the Trinity or even contradicted the defined doctrine. Prior to definition, doctrinal confusion is expected as the Fathers are grappling with the mysteries of the faith in an attempt to puzzle out the doctrines of the Church. The process between doctrinal chaos to doctrinal clarity is called the development of doctrine. By the end of the patristic age a broad and deep witness was arrived at on most of the cardinal doctrines of the Catholic faith. These include the Blessed Trinity, the nature of Christ, the canon of Scriptures, justification and grace, infallibility of the Church, and doctrines concerning Theotokos, just to name a few.
