The Patristic Period is the period in the history of the Christian church from around 100 AD until the 8th century. The period is characterized by divisions within the Church on matters of theology and doctrine, by the definition of the great creeds which are still used in the church, and by the theological writings of the Church Fathers such as Augustine.
The church fathers are generally divided into the Ante-Nicene Fathers, those who lived and wrote before the First Council of Nicaea in 325 AD; and the Nicene and Post-Nicene Fathers, those who lived and wrote after that date. In addition, the fathers are divided into those who wrote Greek and those who wrote in Latin. Examples of the former are Justin Martyr and Cyril of Alexandria. Among the Latin Fathers are Tertullian and Augustine of Hippo.
