“Luther's return from the cloister to the world was the worst blow the world had suffered since the days of early Christianity.”

“The otherworldliness of the Christian life ought, Luther concluded, to be manifested in the very midst of the world, in the Christian community and in its daily life. Hence the Christian's task is to live out that life in terms of his secular calling. That is the way to die unto the world. The value of the secular calling for the Christian is that it provides an opporunity of living the Christian life with the support of God's grace, and of engaging more vigorously in the assault on the world and everything that it stands for. Luther did not return to the world because he had arrived at a more positive attitude towards it. Nor had he abandoned the eschatological expectation of early Christianity. He intended his action to expres a radical criticism and protest against the secularization of Chrisitanity which had taken place within monasticism. By recalling the Christians into the world he called them paradoxically out of it all the more. That was what Luther experienced in his own person. His call to men to return to the world was essentially a call to enter the visible Church of the incarnate Lord.”

“Jesus Christ lived in the midst of his enemies. At the end all his disciples deserted him. On the Cross he was utterly alone, surrounded by evildoers and mockers. For this cause he had come, to bring peace to the enemies of God. So the Christian, too, belongs not in the seclusion of a cloistered life but in the thick of foes. There is his commission, his work. 'The kingdom is to be in the midst of your enemies. And he who will not suffer this does not want to be of the Kingdom of Christ; he wants to be among friends, to sit among roses and lilies, not with the bad people but the devout people. O you blasphemers and betrayers of Christ! If Christ had done what you are doing who would ever have been spared' (Luther).”

“Luther had said that grace alone can save; his followers took up his doctrine and repeated it word for word. But they left out its invariable corollary, the obligation to discipleship...The justification of the sinner in the world degenerated into the justification of sin and the world. Costly grace was turned into cheap grace without discipleship.”

“If we want to be Christians, we must have some share in Christ’s large-heartedness by acting with responsibility and in freedom when the hour of danger comes, and by showing a real sympathy that springs, not from fear , but from the liberating and redeeming love of Christ for all who suffer. Mere waiting and looking on is not Christian behavior. The Christian is called to sympathy and action, not in the first place by his own sufferings, but by the sufferings of his brethren, for whose sake Christ suffered.”

“Let the Christian remain in the world, not because of the good gifts of creation, nor because of his responsibility for the course of the world, but for the sake of the Church. Let him remain in the world to engage in frontal assault on it, and let him live the life of his secular calling in order to show himself as a stranger in the world all the more. But that is only possible if we are visible members of the Church. The antithesis between the world and the Church must be borne out in the world. That was the purpose of the incarnation. That is why Christ died among his enemies. That is the reason and the only reason why the slave must remain a slave and the Christian remain subject to the powers that be.”

“Justification is the means whereby we appropriate the saving act of God in the past, and sanctification the promise of God's activity in the present and future...Justification is primarily concerned with the relation between man and the law of God, sanctification with the Christian's separation from the world until the second coming of Christ...Justification is the new creation of the new man, and sanctification is his preservation until the day of Jesus Christ.”
