Col 2:8-10: "Captive"
Do (not): “Captive” (v. 8)
True Christian philosophy “take[s] captive every thought to make it obedient to Christ” (2 Cor. 10:5). Philosophy is the love of wisdom, but if one loves wisdom that is not Christ (the Sum of all wisdom, Col. 2:3), he loves an empty idol.
What is clear is that the description is pejorative: the “philosophy” is the product of mere human speculation and does not put its adherents in touch with divine truth
Christ is the one in whom God exclusively is to be found, the one through whom the world was created and through whom it is redeemed, and the one who has decisively defeated all the hostile powers. Any teaching that in any way detracts from Christ’s exclusive role is by definition both wrong and ineffective
The teachers themselves are probably not denying that Christ was central to God’s saving purposes. They seem rather to be arguing that certain practices must be added on in order to achieve true spiritual fulfillment. But, for Paul, in this case, addition means subtraction: one cannot “add” to Christ without, in effect, subtracting from his exclusive place in creation and in salvation history.
