Paul writes against any philosophy of life based only on human ideas and experiences. Paul himself was a gifted philosopher, so he is not condemning philosophy. He is condemning teaching that credits humanity, not Christ, with being the answer to life’s problems. That approach becomes a false religion. There are many man-made approaches to life’s problems that totally disregard God. To resist heresy you must use your mind, keep your eyes on Christ, and study God’s Word.
Don’t let anyone capture you with empty philosophies and high-sounding nonsense that come from human thinking and from the spiritual powers of this world, rather than from Christ. – Colossians 2:8
