Ignatius turned the road to execution into seven letters the church never forgot. As he was being taken to Rome under Trajan, he wrote to churches about Christ's real flesh, the Eucharist, martyrdom, unity, and the bishop as the visible centre of a local church. He is the first writer to use 'Catholic' as a description of the universal church. If later Christians argue about bishops, sacraments, unity, or martyrdom, Ignatius is already in the room.
