Basil of Caesarea
Early Christian writings rejecting abortion are the "Didache", the "Epistle of Barnabas", the "Apocalypse of Peter", and the works of early writers such as Tertullian, Athenagoras of Athens, Clement of Alexandria and Basil of Caesarea. The earliest Church legislation did not make a distinction between "formed" and "unformed" fetuses, as was done in the Greek Septuagint version of ; this position can be found in the writing of early Church Fathers such as Basil of Caesarea and early Church council canons (Elvira, Ancyra).
