So, then, just as you received King Jesus the Lord, you must continue your journey in him. You must put down healthy roots in him, being built up brick by brick in him, and established strongly in the faith, just as you were taught, with overflowing thankfulness. [Colossians 2:6 (NTE)]
Although many Christian writings refer to Polycarp, only one of his letters remains. Written to the church at Philippi sometime before 150 AD. Polycarp addressed the behavior of a greedy bishop named Valens, explained that true righteousness sprang from true belief, and warned against false teachings. Containing 12 quotes from the Old Testament and 100 quotes or paraphrases from the New, this epistle has been described as a “mosaic of quotations” from the Bible. Using language from what now are known as the books of Matthew, Mark, Luke, Acts, Romans, 1 and 2 Corinthians, Galatians, Ephesians, Philippians, 1 and 2 Thessalonians, 1 and 2 Timothy, Hebrews, 1 Peter, and 1 and 3 John, his letter is testimony both to the existence of these texts by mid-2nd century and that the early church already believed them to be inspired Scripture.
In his letter, Polycarp addressed the heresies of Gnosticism and Marcionism that had found their way into the early church. Probably a greater threat to the early church than persecution, Gnosticism was a combination of religion and philosophy taken from Babylonian beliefs, Zoroastrianism, Hinduism, and assorted cults, along with the philosophies of Greeks like Plato, Aristotle, and Pythagoras. In a nutshell, early Gnostics believed in dual realities — essence/spirit/light (considered good) and material/body/dark (considered evil) — much like the Chinese yin and yang. They also believed in the secret knowledge or gnosis of salvation. Of course, such a philosophy can’t really be put in a nutshell. Polycarp’s student Irenaeus (who later became bishop of Lyons) said this about Gnostics, “Since their teachings and traditions are different, and the newer ones among them claim to be constantly finding something new, and working out what no one ever thought of before, it is hard to describe their views.” According to Gnosticism, since God is a spirit (which is good) and the world is made of matter (which is evil), the world couldn’t have been created by a good God; rather, it was created by a lesser deity named Demiurge. Believing flesh evil, they rejected the incarnation; rather than Christ coming as flesh, Gnostics believed He took possession of the man Jesus’ body at his baptism and departed his body before the crucifixion. Believing salvation came through secret knowledge to a select few contradicted Christianity’s promise of salvation to all by grace through faith.
Marcion (85-160 AD) was an influential Gnostic who tried to create a “new brand” of Christianity (Marcionism). In a nutshell, Marcionism redefined God. Rejecting Old Testament teachings, Marcion claimed the God of the Old Testament was not the same deity as the God of the New, Jesus was the son only of the New Testament God, and the prophecies of the Old Testament predicted a yet-to-come earthly messiah for the Jews. Marcion discarded the entire Old Testament and, believing the Apostles misunderstood Jesus, cut the New Testament down to heavily edited versions of Luke’s gospel and just ten of Paul’s letters.
In his letter, Polycarp warned the Philippians that “whosoever perverts the oracles of the Lord to his own lusts, and says that there is neither a resurrection nor a judgment, he is the first-born of Satan. Wherefore, forsaking the vanity of many, and their false doctrines, let us return to the word which has been handed down to us from the beginning.” May we do the same!
If you believe what you like in the gospels, and reject what you don’t like, it is not the gospel you believe, but yourself. [Augustine]
