Roman province along the coast of the Black Sea in which there were several Jewish communities. Some Jews from the region were in Rome for Pentecost (Acts 2: 9), and Aquila was born there (Acts 18: 2). Christians in Pontus are addressed by 1 Pet. 1: 1, and advice on their treatment was sought by the provincial governor Pliny in letters (110–12 CE) to the emperor Trajan. The 2nd‐cent. heretic Marcion, who wished to detach the Church from the OT, was a shipping magnate in Pontus.
