What does it mean that Jesus is the head of the church? This concept of Jesus being over the church is mentioned numerous times in the New Testament, both implicitly and explicitly. In Colossians 1, Paul calls Jesus the head of the body, the beginning, and the first born from the dead, with the end result of him being preeminent in all things (Col 1:18). Jesus is the head, becoming the center of all things concerning God and his church. Paul mentions Christ’s headship in Ephesians 5 as well; and he compares Christ’s headship over the church to a husbands relationship to his wife, telling us that Christ’s headship is one of nourishment and sanctification toward his church; similarly, husbands should care for and nourish their own wives (Eph 5:23-29). But what is Paul trying to convey here?
When Paul speaks of headship, he is talking primarily about representation.
Biblically, what we must understand is that God deals with people by way of representatives. Whatever happens to that representative happens to those under him. This principle goes throughout the entire history of the scriptures.
For instance, when God created Adam, he gave him certain responsibilities. Adam was to cultivate the garden that God had given him, and to be fruitful and multiply (Gen 1:28). To Adam alone was given this responsibility — and Eve was given as a helper to assist him in accomplishing his God-given tasks. Also, God prohibited Adam from certain things. He was not to eat of the tree of the knowledge of good and evil (Gen 2:17). If he were to eat of it, he would surely die. Of course, we find that Adam and his wife did eat of the tree. But it’s interesting just how God punishes Adam and Eve for their disobedience. First, God holds Adam alone responsible, not Eve (Gen 3:9-10). Second, because of Adam’s failure, God punishes all of humanity, not just the pair. Paul later picks up on this concept, and tells us that we are sinful because of one man’s sin (Rom 5:12). What this indicates is that Adam was a God-ordained representative for all humanity. If he would have been obedient, we would have all benefitted. But because he chose to disobey, we all fell into sin.
From Adam and on, the principle of headship as representation can be traced from Old Testament to New. God chose Noah as the head of a new humanity (Gen 6-9), Abraham as the head of a new nation Israel (Gen 12-22), Moses as the head of the Mosaic Economy (Exod 19-20), and David as God’s eternal kingly dynasty (2 Sam 7). What is especially interesting when reading about the institution of the Mosaic Law, we find that the people of Israel waited at the bottom of Mount Sinai as Moses went and spoke before God on their behalf (Exod 19:1-3). And God interacted with the people of Israel through Moses alone. In that sense, Israel went in Moses into God’s presence. Paul picks up on this in 1 Corinthians 10, telling us that Israel was baptized into Moses in the Red Sea (1 Cor 10:2). What an interesting way to articulate the concept!
And when we arrive at the New Testament, we find out that all of these representative heads were merely pointing to the true cosmic representative, Christ. Matthew describes Christ becoming the true Moses who teaches God’s people from the mountain (Mt 5-7). Matthew also presents Christ as the true Israel, God’s true righteous servant (Mt 2:13-4). Paul calls Christ the last Adam, making him the head of a new humanity (1 Cor 15:22). He also calls Christ the true seed of Abraham who blesses the nations through his life and death (Gal 3:16). And, Luke presents Jesus as the true Davidic king whose kingdom will last forever (Lk 1:32-33). In this way, Jesus is the ultimate head who realizes all of God’s redemptive purposes. He realizes Adam’s mission, Israel’s purpose, and David’s kingship. In this way, Jesus is the fountain of all things.
So when we call Christ our head, what we mean is that he represents us before God. This is why Paul can say of himself: “I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me” (Gal 2:20). If we are in Christ, this means that the death that Jesus died to sin, we also died. It means that the life he now has is our life (Col 3:1). It means that his reign is our reign (1 Cor 3:21). If Christ is your head, you are hidden in him, seated at the right hand of God, clothed in his righteousness, dead to sin, and alive to God (Rom 6, Col 3:1-4).
Christ is our representative. This is what headship means. In Christ, what happens to Jesus happens to you! This is why Paul tells us that Christ’s headship means that he is preeminent in all things (Col 1:18). It is what Paul means when he tells us that our chosenness is in Jesus (Eph 1:3-10). We have been chosen in Christ before the ages began. And the result is that Christ is our representative, and all things are be summed up in Him alone (Eph 1:10).
