Paul's Challenge to the Colonists

Paul's challenge to the colossians is essentially, why settle for empty philosophy when you have the fulness of god and his authority bodily present in christ? Christ is over all other powers. They should not satisfy themselves with lower principles when they have christ, who is above all. The ulness of deity dwells in him. We have the full reality of god in him, and should not allow any one to pawn off a lesser substitute to us. This doesn't mean that we need baptism in order to be saved on the last day. That's not quite the point that paul is making. Rather, there is something about the social body here that i think is in play.
