Ephesians 1:23

“which is His body, the fulness of Him that filleth all in all”

“Which is”: The church just mentioned is the body of Christ. “His body”: The church and the body of Christ are the same relationship. Since one is said to be baptized into "one" body (1 Corinthians 12:13), this means that baptism stands between one and being. member of Christ's church (Acts 2:38; Acts 2:41; Acts 2:47). There is only "one" body (Ephesians 4:4). This "one" body is not composed of differing denominations, but faithful individual Christians (1 Corinthians 12:27). Only those baptized for remission of sins are in this one body. In addition, the "one body" is composed only of those Christians who are in subjection to Christ. There is only one Church that God recognizes as belonging to Christ. (Matthew 16:18). Churches that do not teach that baptism stands between the believer and salvation (Acts 22:16; 1 Peter 3:21), are not Christ's church. Churches that do not follow the teachings of Christ, are not Christ's church (2 John 1:9).

“The fullness”:. number of interpretations for this statement exist, but in the end, this statement should not be that hard to understand. The phrase "fulness of Him", refers back to the last mentioned object, the church or body of Christ. Hence the church is filled completely and totally by Christ. Some view this as saying that “He imparts to it, as His body, all its life, its strength, its grace, its gifts” (Erdman p. 47). Paul had already noted that all spiritual blessings are in Christ (Ephesians 1:3), and being in Christ and being in the body of Christ are the same thing. Thus, every blessing, and all that God can mean to us is only found in the church. Jesus is the fullness of God (Colossians 2:9), which means that everything that makes God, “God”, is found in Jesus. In like manner, the church is the fullness of Christ, everything that Christ can mean to. human being is found in the church.
