Pastors are leaders, but they are not heads. Leadership is horizontal, but headship is vertical.
I expected such a foolish answer from you because you don't know that "the head" is simply a metaphor of authority and leaders are in positions of authority whether you like or not whether you accept it or not.
I Cor. 12:21
And the eye cannot say unto the hand, I have no need of thee: nor again the head to the feet, I have no need of you.
The above text proves that there were members in the church at Corinth that functioned as "the eye" and "the hand" and "the feet" as well as "THE HEAD." That is a metaphor of a position of AUTHORITY in the body whereas Christ is "the head" OVER the body including the member functioning as the undershepherd.
"he that ruleth" - Rom. 12:8
"Obey them that have the rule
over you" - Heb. 13:17
"OVERseers" - Acts 20:28
"OVERsight" - I Pet. 5:4
Whether you agree, disagree, like, love or hate it the metaphor of "the head" in I Cor. 12:21 describes the member in the church who functions in a position "OVER" the flock or in the position of some kind of "authority" as that is the meaning of the metaphorical use of "the head" as Paul cannot possibly be speaking of a LITERAL head in I Cor. 12:21 any more than he can be speaking of a LITERAL body in I Cor. 12:13-27.
This indisputable fact destroys your whole concept of "the church" as well as your whole doctrine of "soteriology" as this proves the metaphorical body in question is precisely what Paul says it is in verse 27 the church at Corinth with its leadership placed over them by the Holy Spirit (Acts 20:28).
I Cor. 12:21 refers to "the head" as a position of a member IN the body whereas Christ is "the head" OVER the whole body and the whole body has a "head" just as a wife has a "head" on her body and yet the husband is "the head" OVER the whole body of the wife.
Look at I Cor. 11:3. Christ is "the head" over every man but that does not mean the male torso is without a physical head. The man is "the head" over the woman but that does not mean the female torso is without her physical head. The metaphor "the head" simply means "authority" without any physical or spiritual union to the body of the man or woman.
In I Cor. 12:21 we have the use of this metaphor for "authority" assigned to a member IN the body as his function to edify the other members in this metaphorical body of Christ. Yet, the metaphor of "the head" refers to the position of Christ as final authority OVER the whole metaphorical torso including its own metaphorical "head" IN the body. There is simply a resident leader IN this body which as a whole is UNDER the ultimate Leader Jesus Christ.
