§ 189. Gregory Thaumaturgus.
Schaff introduces Gregory Thaumaturgus as one of the most important disciples of Origen in Alexandria (Schaff 2014, loc. 22646). Gregory was converted by Origen, then learned from him for some eight years before serving as bishop in Neo-Caesarea in Pontus between 244 and 270 (Schaff 2014, loc. 22652). He was considered to have seen the conversion of all but about 17 people in his area of service during that time. Gregory’s works and a creed ascribed to him were not known by Eusebius, but by the end of the fourth century he was recognized as a teacher and a miracle worker (Schaff 2014, loc. 22657).
Schaff provides the Greek and a translation of the creed ascribed to Gregory, as it has come down to us (Schaff 2014, loc. 22672). Schaff further provides a partial catalog of miracles ascribed to Gregory by Gregory of Nyssa in the 4th century and defended by Cardinal Newman in the 19th century (Schaff 2014, loc. 22693).
