The Church Fathers are men who wrote in the first four centuries of Christianity. Especially in Roman Catholic circles they are called Doctors of the Church.  To this list Rome has added many more that are not necessarily recognized in the East.

Works of fathers have been available in English since the 19th century and fill many volumes. Those who wrote prior to the council of Nicena are commonly called the Ante-Nicene Fathers. Those after the First Council of Nicaea are called Nicene of often the Post-Nicene Fathers. In Protestant circles the Anti-Nicene Fathers are usually considered most important. The very earliest Church Fathers, of the first two generations after the Apostles of Christ, are usually called the Apostolic Fathers. Famous Apostolic Fathers include Clement of Rome, Ignatius of Antioch and Polycarp of Smyrna.  

The Fathers are grouped in various ways by the different Christian churches. The following table shows those men commonly recognized as the Church Fathers by both East and West. Additional groupings include the Desert Fathers and the Cappidocian Fathers.  It is probably helpful to note that the first Council of Nicea was in 381 so this grouping that is commonly called the Church Fathers actually spans the council. We also note that there are 5 of each providing a sort of balance. The Churches of the East and West recognize their common roots as this table demonstrates.I have added a column for the Syriac fathers with the note that the Latin and Greek traditions were protected by the Roman empire and what we in the West call the Byzantine empire. The Syriac church was not so fortunate.

The presence of this on an essentially protestant web site is also meant to show the common roots of all Christianity.
