Bind yourselves to your brethren. Those bound together in love bear everything with ease…. If now you want to make the bond double, your brother must also be bound together with you. He wants us to be bound together with one another, not only to be at peace, not only to be friends, but to be all one, a single soul. Beautiful is this bond. With this bond we bind ourselves together both to one another and to God. This is not a chain that bruises. It does not cramp the hands. It leaves them free, gives them ample room and greater courage.
St. John Chrysostom
Homily on Ephesians 9.4.1-3
