The Ante-Nicene Church





Who Gregory Thaumaturgus was
A pagan law student of Pontus, Gregory stopped at Caesarea en route to law school at Berytus, met Origen, and stayed five years. His farewell Panegyric to Origen is antiquity’s warmest portrait of a teacher and the fullest record of any ancient curriculum — logic, physics, ethics, then the Scriptures. Sent home a bishop around 240, he found (the famous tale runs) seventeen Christians in Neocaesarea and left seventeen pagans at his death. His short Declaration of Faith is a proto-Nicene creed of startling precision; his Canonical Epistle, written after Gothic raiders swept Pontus, is early canon law with a pastor’s face. Basil’s grandmother Macrina the Elder learned the faith from his tradition — making him godfather to the Cappadocians.
Also listed in bishops beyond the great sees and roman emperors.
