The Ante-Nicene Fathers: The Writings of the Fathers Down to A.D. 325 (abbreviated ANF)[1] is a collection of books in 10 volumes (one volume is indexes) containing English translations of the majority of Early Christian writings.[2] The period covers the beginning of Christianity until the promulgation of the Nicene Creed at the First Council of Nicaea.
The Ante-Nicene Fathers: Translations of the Writings of the Fathers Down to A.D. 325 (ANF) and A Select Library of Nicene and Post-Nicene Fathers of the Christian Church (NPNF) are well over a century old, but they continue to be reprinted by publishers and cited by writers in the field.
