Colossians 2:8 Does Not Condemn Philosophy
Some Christians view reason as the enemy of faith. For this reason (pun intended), they reject philosophy. This philosophy (pun intended, again) is known as Christian anti-intellectualism. As you can hopefully already see, it is self-refuting. Nonetheless, some point to Colossians 2:8 to try and defend this odd philosophy. Only by ripping this verse out of context could you get an interpretation that would defend a self-refuting position.
