The Doctrine of One Body

As we began last time, doctrine is the basis of unity and Ephesians 4:4-6 list seven spiritual realities that unite all true believers. Contained in these seven principles is the very essence of Christianity, that is, its foundational truths. Each of these in-turn has two emphases: its meaning and its application. The first basis is one body.

First, the meaning of one body can only be one thing—the Universal Church, the Body of Christ, the Church as an organism, to which Paul has referred several times in this letter.

There are many other references to this in Scripture. In Matthew 16:18, Jesus said He would build His Church” (singular), not “churches” (plural). While before his conversion Paul no doubt persecuted individual churches, he recounts in I Corinthians 15:9 how he persecuted “the church,” that is, the entire Body of Christ. That is why the Lord Jesus asked, “Why persecutest thou Me?” (Acts 9:4), that is, My Body, all believers. Later in Ephesians 5:25, Paul also declares that Christ gave Himself for “the church,” that is, the entire Body. That Body was formed on the Day of Pentecost and includes every true believer. He emphasized the same truth to the Romans: “For as we have many members in one body, and all members have not the same office: So we, being many, are one body in Christ, and every one members one of another” (Rom. 12:4-5).

So there is one body, not many. There is not one church that is for Jews, another for Gentiles, another for men, another for women, another for Caucasians, another for Negroes, and another for Asians. There is one, a single unified Body of Jesus Christ, of which all believers are part. As we studied carefully back in 2:14-18, God has made us all one. Shame on us if we build back any walls that He has broken down.

One word of caution is in order here. A common teaching in today’s pragmatic atmosphere is that only the Universal Church is important. This emphasis tears down and de-emphasizes the Local Church, which is, in fact, actually more important in some ways. The Local Church is the Church as an organization. More precisely, it is the local assembly of believers, organized according to Scriptural guidelines, that carries out all outward ministry. The Local Church is God’s instrument for working in the world today, and each is to carry out all ministry. That is why Paul founded Local Churches. Each is for God’s people to gather for worship, exercise their gifts, and equip them for service. As Paul makes clear later in Ephesians 4:11-16, God has given certain men “for the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ,” and this obviously takes place in the local church, as is also made plain in the book of Acts. Paul likewise wrote to Timothy, the pastor of a Local Church, “But if I tarry long, that thou mayest know how thou oughtest to behave thyself in the house of God, which is the church of the living God, the pillar and ground of the truth” (I Tim. 2:15 with context). So as we will see, the Local Church is the training ground for ministry.

Second, the application of one body is that the Universal Church is a basis of unity and fellowship. One example of those who don’t accept this principle are certain denominations (or some groups who refuse to be even called a denomination) who maintain that their local assembly, along with other local assemblies who agree with them, are “The Church.” In this view, no one else is part of the Church, no matter what they believe. That is, of course, an arrogance that is hard to fathom. Biblically, no earthly denomination or group can be called “The Church.” Every true believer who is in agreement concerning the unique revelation of God through and in Jesus Christ is part of Christ’s Body. Any other attitude destroys unity and any possibility of fellowship.
