5. READ: COLOSSIANS 2:1-19
b. What is Christ the head over?
Answer: Christ is the head over every power and authority, (verse 10).
The KJV translates "every power and authority" as "all principality and power." "Principality" is from the Greek word arche, which, in this verse, has the sense of "dominion" or "rule." It always signifies "primacy," whether in time or in rank. (Primacy: a being first in time, rank, etc., supremacy.)
The word "power" in the KJV is from the Greek word exousia, which properly means "authority"--in distinction from dynamis, which means "power."
The correct combination here is that "Christ is the head over every rule and authority." Every other rule and authority comes after Christ, whether angles, aeons (also "eon," an extremely long, indefinite period of time), kings, etc. He Who is the Head over every power/rule and authority has the RIGHT to command of His disciples that they proclaim Him to all, and that all obey everything He has commanded. We need to understand the full power and authority which calls us to the hope that is in us, and that NOTHING can overcome this power and authority:
Matthew 28:18-20: "Then Jesus came to them and said, 'ALL authority in heaven and on earth has been given to Me. THEREFORE go and make disciples of all nations, baptizing them in the Name of the Father and of the Son and of the Holy Spirit, and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.'"
John 16:33: [Jesus said,] "I have told you these things, so that in Me you may have peace. In this world you will have trouble. But take heart! I have overcome the world."
Ephesians 1:18-23: "I pray also that the eyes of your heart may be enlightened in order that you may know the hope to which He [God] has called you, the riches of His glorious inheritance in the saints, and His incomparably great power for us who believe. That power is like the working of His mighty strength, which He exerted in Christ when He raised Him from the dead and seated Him at His right hand in the heavenly realms, far above all rule and authority, power and dominion, and every title that can be given, not only in the present age but also in the one to come. And God placed all things under His feet and appointed Him to be head over everything for the church, which is His body, the fullness of Him Who fills everything in every way."
Colossians 2:15: "And having disarmed the powers and authorities, He [Jesus] made a public spectacle of them, triumphing over them by the cross."
Revelation 17:14: "They will make war against the Lamb, but the Lamb will overcome them because He is Lord of lords and King of kings--and with Him will be His called, chosen and faithful followers."
