Commentaries:
The philosophy of Gnosticism taught that everything physical was evil and that people could attain a higher spiritual understanding through effort. It was the type of philosophy that its adherents thought could be used to enhance or improve anyone's religion. In Paul's letter to the Colossians, we read of this same philosophy having an influence on the church there. It was characterized by strict legalism, a "taste not, touch not" attitude, neglect of the body, worship of angels, and a false humility (Colossians 2:18-23).

Does Paul Condemn Observing God's Holy Days?
Many of the people who had come into the Colossian church had brought their pagan philosophies with them, and they soon began to have an adverse influence on the entire congregation at Colossae. Paul corrects the people in the church who were doing this in Colossians 2:20-23.
Apparently, some of the people had begun thinking that self-imposed asceticism could somehow contribute to their salvation, and had begun turning away from trusting in Christ. They had more faith in their unchristian works. Paul warned them about this in Colossians 2:8: "Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ."
