Ephesians 4:2-7 English Standard Version
2 with all humility and gentleness, with patience, bearing with one another in love, 3 eager to maintain the unity of the Spirit in the bond of peace. 4 There is one body and one Spirit—just as you were called to the one hope that belongs to your call— 5 one Lord, one faith, one baptism, 6 one God and Father of all, who is over all and through all and in all. 7 But grace was given to each one of us according to the measure of Christ’s gift.
This instruction is given to the workers of these ministry gifts; the apostles, the prophets, the evangelists, the shepherds and teachers. The oneness found here is the Lord, faith, baptism, God, and the Father of all. In this oneness is not unity. We can distinguish that by the measure of grace that is given to each of the ministry gifts. Each has a role that differs from the other.
Unity of faith is only found in He who is over all, through all and in all. What is common among all the ministry gifts is the goal of those ministries, serving the will of God in the maturing of Christ’s bride. Verse 12 calls this the building up the body of Christ.
We are in fact each one of us part of the body of Christ and at the same time His betrothed. As such we have not attained to our pure white robes of righteousness which are our own. We only have the righteousness of Christ in us to deal with what remains of our humanity. Faith is the active agent of change which ensures that the service ministries can be effective in serving the will of God by the faith that binds us all together.
This is seen because of one faith and yet different graces.
