5 Biographical Summaries of Early Church Fathers


Polycarp of Smyrna

Polycarp lived through the second half of the first century AD and the first half of the second century.  From a statement he is recorded to have made at his martyrdom, it is assumed that Polycarp was baptized as a child and didn’t have a moment in his life where he did not know the Lord.   He had great influence in the early Christian Church, largely because he was a disciple of the Apostle John.  His apostolic connection helped land him the Bishop office of Smyrna, and it also placed him in a very important role of preserving the orthodox teachings of the Apostles, which he did with tenacity.  It is reported that he called Marcion out to his face in Rome, calling him “the first born of Satan.”  He also pulled believers away from Gnosticism.  His willingness to die as a 2nd generation Church Father was another way in which he carried on like the apostles (all except John that is).  Today his writings only have survived through a letter he wrote to the Philippians, which is an important text for the modern church since it is one of the earliest writings we have from Christendom outside of the Biblical texts.

Irenaeus of Lyons

Irenaeus was born in Smyrna in the first half of the second century AD and he lived to see the close of that century.  Having been a student of Polycarp in his youth, becoming the Bishop of Lyons late in his life, he carried on a chain of successive leadership tracing back to the apostles.  In fact, Irenaeus prescribed such connection to apostolic succession for all bishops, stressing that they all taught what the apostles had received from Christ and passed on to followers such as his teacher, Polycarp.  It is on this authority that he spoke against the Gnostics who claimed to have a knowledge from outside of direct revelation from Jesus.  His refutation of the Gnostics, in particular the flavor of Gnosticism that derived from the followers of Valentinus, has been preserved in his work Against Heresies.  It is from this work that the modern Church had the most information about Gnosticism before the discovery of the Dead Sea Scrolls.  His writings also prove helpful to demonstrate the early formation of the New Testament Canon, since Irenaeus’s writings provide the first record of acknowledging a four-fold Gospel in Church writing and he references every text of the New Testament, except 3 John, in Against Heresies.  He may, or may not have died as a martyr.


Jerome, AKA Eusebius Hieronymus, was born in Stridon just prior to the middle of the fourth century AD, dying around 420 AD.  In is lifetime he practiced monasticism as a desert hermit, was ordained a priest, served as a secretary to Pope Damascus, and helped found a monastery in Bethlehem.  Jerome was a prolific translator, translating numerous sermons and commentaries of Church Father Origen, for instance.  His greatest and most long-lasting impact on the Church was his translation of the Vulgate (Latin) Bible.  His translation work, in particular on revisions of the Septuagint (Greek version of the New Testament) led him to the understanding that the only inspired text of the Bible is that of the original text.  In addition to his translations, he added much to the Church’s collection of exegetical commentaries as well as throwing his hat into to the arguments of doctrinal discussion in his day concerning the value of virginity compared to marriage, the ever-virgin state of Mary, the value of asceticism, defending the use of the work of Origen, and writing against Pelagianism (though Jerome was likely a synergist himself).

The Cappadocian Fathers

Arius was an early fourth century priest who taught that Jesus was not eternal.  He taught that Jesus was a created being.  To formulate a catholic response to the teachings of Arius was the main reason Emperor Constantine I called the Council of Nicaea in 325 AD.  This council rejected Arius’ teachings (Arianism) and formulated the Nicene Creed as a proper Trinitarian statement, which adopted the term “of one substance” to refer to describe the oneness in divinity that the Father, Son, and Holy Spirit all shared.  After the council, not every church bishop kept to Nicene Creed and fell back to Arianism.  Soon after the Nicene Creed, Gregory of Nazianzus, Basil of Caesarea, and Basil’s brother, Gregory of Nyssa, were born.  All three were from Cappadocia and they were friends and worked together to advance and cement the formed language of the Trinity that God exists as three persons in one essence.  Their preaching and writing was significant in putting an end to Arianism in the fourth century and was crucial in the Council of Constantinople in 381 that re-affirmed the Nicene Creed.  Together these three men are known as the Cappadocian Fathers.

John Chrysostom

John Chrysostom (347–407 AD) was born John in Syrian Antioch.  He was appointed as the Bishop of Constantinople in 398. Chrysostomos means “golden-mouth” and is added to his given name as a result of his powerful sermons.  His homilies focused on living the crucified life and railed against the excesses and sinful indulgences of his day that were woefully present in the upper-echelon of the secular world and even the Church. Many loved his proclamations, but those on high did not appreciate his pointed applications at them, so he was deposed from this position and then sent into exile where he died.  Around 600 of his homilies survive today.

Islam and the Five Pillars

Christianity speaks of a foundation for our beliefs – Jesus Christ!  
Islam has pillars.  
Pillars, of course, hold up the roof of a building.  The pillars of Islam are then viewed as holding up the Islamic faith.  Following these pillars are essential to all Muslims.  Salvation comes through observing these pillars, yet, there is no guarantee to any Muslim that he or she has followed these well enough, as well as having other good works in their lives, enough to warrant salvation from Allah!
The Five Pillars of Islam
  1. Creed – The creed of Islam is “There is no God but Allah, and Muhammad is his messenger.”  When this single sentence is spoken in faith it makes a person a Muslim.
  2. Prayer – Muslims must pray five times a day facing Mecca.
  3. Charity to the Poor – Muslims must give a percentage of their income to the poor.  Generally, this is 2.5%.
  4. Fasting during Ramadan – Muslims must fast from food and water every day of the ninth month of the Muslim calendar.  This fast is known as Ramadan.   When the sun goes down, they can eat and drink.
  5. Pilgrimage to Mecca – This pilgrimage is called Hajj.  Muslims must travel to Mecca once in their lifetime if they have the financial means to do so.  Once in Mecca, there is is a series of numerous acts that must be performed, but the central task involves worship in the Kabbah.

So… how can a Christian present the Christian faith to a Muslim using these five pillars? 

First, ask questions, even if you already know the answers.  Show that you want to learn from them.  Ask,  “What are the five pillars to you?”

For the Creed, which for them is “There is no God but Allah, and Muhhammad is his messenger,” you can share that Christianity also has creeds.  The Apostles’ Creed and the Nicene Creed.  You could also share that you too believe in only one God.  They’ll likely argue that… and say that you believe in three gods.  But you can then share the Christian faith to them more.

For the daily prayers, you can ask questions about what are the prayers you say?  Why do you have to say them in Arabic?  You can can share that Christians pray too, and that God hears our prayers at all times, not just at certain moments, because he is all powerful and knows all things and wants to listen to what his children have to say.

Charity – you can share that it’s good that they give to the poor.  You can share that Christians give too.

Fasting – you can share that Christians fast too, but that it’s optional for us, and that we can do it anytime we want, and that the purpose for the fasting for us is lead us to pray and to remind us to pray.

Hajj – you can share that to Christians this entire life is a pilgrimage!  This is not our home.  Our home is in heaven with God and we are just strangers passing through this world to our eternal home with God.

They may even ask you more questions about these similarities.  If you have a Bible you can share verses from the Bible with them.  Many Muslims have not read the Bible, yet they believe that the prophets of the Bible, and even Jesus, were prophets for Allah, so their words should be authoritative (although they believe the Bible has been corrupted).
