How do we know that Christ is the Head of all principalities and powers?

The New Testament provides clear affirmation of Christ's authority over all realms of power. Ephesians 1:21 specifies that Christ is seated far above all rule, authority, power, and dominion, not only in this age but also in the one to come. This passage emphasizes that no spiritual or earthly power exists outside of His sovereign rule.

Moreover, Colossians 2:10 reinforces this teaching by asserting that believers are complete in Christ, who is the head over every power and authority. This indicates that Christ's headship encompasses not only the Church but also extends to all creation, including angels, principalities, and powers. This assurance fosters confidence in the Church's mission, for it is governed by the victorious Head who has overcome all forces of darkness.
