BROTHERS and SISTERS, I, a prisoner in the Lord, beg you to walk worthily of the calling to which you have been called. Walk with complete lowliness and humility, with patience, bearing with one another in love, eager to maintain the unity of the Spirit in 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 us all, Who is over all, and through all, and in all.
Saint John Chrysostom:
Great has the power of Paul's chain (imprisonment) been shown to be, and more glorious than miracles. It is not in vain then, as it would seem, nor without an object, that he here holds it forward. It is not merely being a prisoner that is honorable, but being so for Christ's sake. Nothing is equal to this.
