The very earliest Church Fathers, of the first two generations after The Twelve Apostles of Christ, are usually called the Apostolic Fathers.
Famous Apostolic Fathers include
- Ignatius of Antioch
- Polycarp of Smyrna
- Clement of Rome
In addition, the Didache (a brief early Christian treatise (c. 70–160 CE), containing instructions for Christian communities) and The Shepherd of Hermas (a Christian work of the second century, considered a valuable book by many Christians, and occasionally considered canonical scripture by some of the early Church fathers) are usually placed among the writings of the Apostolic Fathers although their authors are unknown.
