In Ephesians, the principle of Christ’s headship is carried to its largest results. The centre of the Church becomes the centre of the universe. God’s plan of the ages is disclosed, ranging through eternity and embracing every form of being, and "gathering into one all things in the Christ."

(Ephesians 4:1-7)  As a prisoner for the Lord, then, I urge you to live a life worthy of the calling you have received. Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace.

There is one body and one Spirit, just as you were called to one hope when you were called; one Lord, one faith, one baptism; one God and Father of all, who is over all and through all and in all. But to each one of us grace has been given as Christ apportioned it.
