What does Colossians 2:20 mean?
Paul begins this verse with a conditional statement, "If with Christ you died to the elemental spirits of the world." There are two possible meanings for this phrase. First, Paul may have had in mind the underlying assumptions used by the false teachers mentioned throughout this chapter. The idea of "elemental spirits" was also mentioned in Colossians 2:8. There, he was speaking of the fundamental theories of a non-Christian, fallen world. A second option is that "elemental spirits" refer to demonic spirits. Paul clearly spoke about spiritual warfare (Ephesians 6:12) and may have had this in mind to wrap up the final verses of the chapter.The context of this statement is the difference between human-centered efforts, versus a Christ-centered reliance on God. For that reason, is seems far more likely that Paul is again referring to worldly thinking and deceptive arguments.
Paul's point in the second half of this verse is clear. If a person really believes that Christ, not the Law, is the focus of their lives, why would they continue to obsess over human rules and regulations? In other words, Paul questioned why the Colossian believers still acted like unbelievers in some areas. Instead of living by faith in their own ability, they were to walk by faith in Christ (Colossians 2:6). The ascetic teachings or rules of false teachers were not binding upon them and offered no advantage.
