Polycarp
Greek bishop of Smyrna and martyr (c. 69 – c. 155 AD), a pivotal transitional figure between the apostolic generation and the next, as tradition — transmitted by his own disciple Irenaeus of Lyon — holds that he personally knew the apostle John and other direct witnesses of Jesus, granting him exceptional spiritual authority at a time when the Church was still seeking to define its doctrine and structure against numerous emerging heresies. He travelled to Rome around 154 to discuss with Bishop Anicetus the controversy over the date of celebrating Easter, one of the earliest documented major debates of ecclesiastical discipline, and, though they reached no agreement, the two maintained communion, setting a precedent of tolerance within diversity that would prove fundamental for the early Church. His only surviving work is the Letter to the Philippians, a brief, practical pastoral letter, of a more moral than speculative tone, exhorting the Christian community at Philippi to fidelity, charity and resistance against heresies — especially Docetism, which denied the physical reality of Christ's body — and extensively quoting the Old and New Testaments, making it a valuable witness to how the biblical canon was taking shape in the early second century. His martyrdom, recounted in one of the earliest and most detailed surviving martyrdom narratives outside the New Testament, the Martyrium Polycarpi, describes him refusing to burn incense to the emperor with the famous reply, 'Eighty-six years I have served him, and he has done me no wrong; how can I blaspheme my King who saved me?', and being burned alive at the stake in an episode tradition embellishes with miraculous elements.
