Charles Ellicott Commentary Colossians 2:10

"and in him ye are made full, who is the head of all principality and power:" — Colossians 2:10 (ASV)

Ye are complete.—Literally, you have been filled up in His fullness, as in John 1:16. So St. Paul had prayed for the Ephesians that they might be filled with (or rather, up to) all the fullness of God, and grow into the measure of the stature of the fullness of Christ (Ephesians 3:19; Ephesians 4:13). To partake of the divine pleroma is not the special privilege of the initiated; it belongs to all who are united to the Lord Jesus Christ.

Principality and power.—See Colossians 1:16. His headship over all angelic natures is dwelt upon with obvious reference to the worshipping of angels. They are our fellowservants under the same Head. (See Revelation 22:8-9.)
