“In “Head over all things”, “head” is not being used in any metaphor so we look at the context and possible meanings of “kephale” (like authority, source, origin) to determine its meaning.”

In my estimation Paul is seeking to show an endless power in the passage. Authority is a weak power. Rather when we consider that Jesus is the source of everything to the Body, we then see the greatness of what Jesus did. After all, if Christ had not died on the cross we would not have salvation and would not be part of His Body. In this way ‘head over all things’ shows His preeminence, shows Christ as origin of all, shows Christ as the one through whom all things are provided, and the one who has everything we need.

Generally speaking (not directing this at anyone) IMO this human lust for seeing authority every where and being an authority is just trying vainly to provide a kind of selfish strength we can control rather than relying wholeheartedly upon God for everything we need to do the things of God and the works of God.

There is an ‘authority’ in Scriptures for believers. It is a spiritual ability or strength to do and be Christlike and help others do and be Christlike. We see this authority in leaders and those who regularly manifest a gifting of the Holy Spirit as a ministering service to the Body of Christ…. such as the five fold ministries. I really don’t think it is beneficial for us to seek for any other kind of authority, especially anything similar to the kinds of authorities the world needs to operate in because of sin.
