Colossians 2:9 For in him the whole fullness of deity dwells bodily, and you have been filled in him, who is the head of all rule and authority. In him also you were circumcised with a circumcision made without hands, by putting off the body of the flesh, by the circumcision of Christ, having been buried with him in baptism, in which you were also raised with him through faith in the powerful working of God, who raised him from the dead. And you, who were dead in your trespasses and the uncircumcision of your flesh, God made alive together with him, having forgiven us all our trespasses, by canceling the record of debt that stood against us with its legal demands. This he set aside, nailing it to the cross. He disarmed the rulers and authorities and put them to open shame, by triumphing over them in him.
The philosophy that threatened the Colossian Christians was a strange eclectic mix of early Gnosticism, Greek philosophy, local mystery religions, and Jewish mysticism. The philosophy threatening the Colossian Christians was so dangerous because it was not obviously sinful and licentious. It was high-sounding and seemed highly intelligent. Philosophy: “It had originally a good meaning, the love of wisdom, but is used by Paul in the sense of vain speculation. The Colossian heresy promoted itself as traditional. It could trace some or many of its ideas back to traditions among the Jews or the Greek philosophers or both. Paul here warned that the tradition of men has no equal authority to the word of God. Common to both Jews and pagans was the basic idea of cause and effect and in a sense, it rules nature and the minds of men. We live under the idea that we get what we deserve; when we are good, we deserve to receive good; when we are bad, we deserve to receive bad. Paul warned the Colossians to not subject themselves to this grace-eliminating kind of thinking and to consider themselves dead to it.
