I did address your point, which was you ignored in immediate context of Col. 2:16,17.
Deal with that before you back up to verse 8. Or deal with them both together.
But to be complete, the greek word for philosophy does not preclude the view of the Jewish traditions and the Mosaic ceremonial law. If those traditions were keeping people in bondage, especially they were being used to oppress gentiles, then they constitute a "philosophy" or vain tradition of men.
I don't normally quote lexicons, but this may be helpful to you:
filosofiva - love of wisdomThe entire tenor of the passage is Jewish, not pagan, e.g., the comparison of circumcision to baptism, the phrase handwriting of requirements (Mosaic code), Let no one cheat you of your reward (which is exactly what the Judaizers were doing to the gentiles).
used either of zeal for or skill in any art or science, any branch of knowledge. Used once in the NT of the theology, or rather theosophy, of certain Jewish Christian ascetics, which busied itself with refined and speculative enquiries into the nature and classes of angels, into the ritual of the Mosaic law and the regulations of Jewish tradition respecting practical life (Strong's Number 5385; The KJV New Testament Greek Lexicon)
So the context does confirm the reading that Paul was very much concerned about gentile belivers being overcome by Jewish traditions, the traditions of men (Just like today, it was very hard even for Jews to tell where the law stopped and the traditions started, nevermind the gentiles, who often got unknowingly caught up in the illusionary piousness of lawkeeping)
It is death to place oneself "under the law".
How about taking a shot at post 25? I'm still confused about what you believe this is saying.
