Polycarp

Polycarp (; Greek: Πολύκαρπος, Polýkarpos; Latin: Polycarpus; AD 69–155) was a Christian bishop of Smyrna. According to the Martyrdom of Polycarp, he died a martyr, bound and burned at the stake, then stabbed when the fire failed to consume his body. Polycarp is regarded as a saint and Church Father in the Eastern Orthodox Church, the Catholic Church, Oriental Orthodox Churches, Lutheranism, and Anglicanism.

Both Irenaeus and Tertullian say that Polycarp had been a disciple of John the Apostle, one of Jesus's disciples. In On Illustrious Men, Jerome similarly writes that Polycarp was a disciple of John the Apostle, who had ordained him as a bishop of Smyrna. Polycarp is regarded as one of three chief Apostolic Fathers, along with Clement of Rome and Ignatius of Antioch.
