Paul has been outlining the new standards which God expects of his new society, the church, especially in terms of its unity and purity. These two qualities are indispensable to a life which is both worthy of the calling and fitting to the status of the people of God. He moves on now to the new relationships in which God’s new people inevitably find themselves, and in so doing he concentrates in the rest of his letter on two further dimensions of Christian living. The first concerns the practical, down-to-earth relationships of the home.
