We may be talking about different church fathers, also know as Apostolic Fathers. Their writings never became part of the Canon: The Apostolic Fathers, also known as the Ante-Nicene Fathers, were core Christian theologians among the Church Fathers who lived in the 1st and 2nd centuries AD who are believed to have personally known some of the Twelve Apostles or to have been significantly influenced by them.[1] Their writings, though widely circulated in early Christianity, were not included in the canon of the New Testament.Netch when looking upon the early church fathers as Roman Catholics that would come under the Ante Nicene fathers period.
They wrote material like
- The First Epistle of Clement
- The Second Epistle of Clement
- Martyrium Ignatii
- Epistle of Polycarp
- Martyrdom of Polycarp
- Fragments of the writings of Papias of Hierapolis, which have survived as quotations in later writers
- One short fragment of the Apology of Quadratus of Athens
- The Didache
- The Epistle of Barnabas
- The Epistle to Diognetus[note 1]
- The Shepherd of Hermas
Not sure if the RCC actually started with Christ as claimed by them, but it is no doubt their not Christian based due to the multitude of antichristian doctrines.
