The fundamentals
No body is complete without a head. There is an old saying, “Anything with no head is dead, and anything with more than one head is a freak.” The Bible plainly teaches that there is structure to all relationships. The ultimate head in all relationships whether social or governmental is God. He is the one who places all heads of government in office (Romans 13:1) and He is the one who is to be the head of the family (Ephesians 5:22-26). Ultimately man must give account to God for all of his activities.
Even though Jesus and God are equal, the Scripture teaches that Christ submits to the authority of the Father. Various passages give account of Christ’s submission to the Father. One of the references is 1 Corinthians 11:3
3 But I would have you know, that the head of every man is Christ; and the head of the woman is the man; and the head of Christ is God.
The head of the church is the Lord Jesus Christ. In Ephesians Paul says, Ephesians 4:15-16 15 But speaking the truth in love, may grow up into him in all things, which is the head, even Christ: 16 From whom the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love. Although we are to do everything we can in the church, it is the power of Christ that makes everything everlasting work.
