"So far as Paul is concerned, guidance for the church is provided by the law of love, not by the 'law of commandments and ordinances' (Ephesians 2:15). In his letters he himself lays down guidelines for his converts and others, often couched in the imperative mood, but these guidelines mostly concern personal relations. . . . Here if anywhere Luther entered into the mind of Paul: 'A Christian man is a most free lord of all, subject to none. A Christian man is a most dutiful servant of all, subject to all.' 'Subject to none' in respect of his liberty; 'subject to all' in respect of his charity. This, for Paul, is the law of Christ because this was the way of Christ. And in this way, for Paul, the divine purpose underlying Moses' law is vindicated and accomplished."
