The Divine demand is absolute. They are not relative demands, which bring more or less blessedness, but they are the absolute demand: joyfully accept the will of God. And there is only one punishment – not the different degrees between the ecclesiastical satisfactions, between the punishment in purgatory, and its many degrees, and finally Hell. There is nothing like this. There is only one punishment, namely the despair of being separated from God. And consequently there is only one grace, namely, reunion with God. That’s all. And to this, Luther – whom Adolf Harnack, the great historian of the dogma, has called a genius of reduction – to this simplicity, Luther has reduced the Christian religion. This is another religion.
Now Luther believed that this was a restatement of the New Testament, especially of Paul. But although his message has the truth of Paul, it’s by no means the full Paul; it is not everything which Paul is. The situation determined what he took from Paul, namely Paul’s conception of defense against legalism – the doctrine of justification by faith. But he did not take in Paul’s doctrine of the Spirit. Of course he did not deny it; there is a lot of it; but that is not decisive. The decisive thing is that a doctrine of the Spirit, of being “in Christ,” of the New Being, is the weak spot in Luther’s doctrine of justification by faith.
In Paul the situation is different. Paul has three main centers in his thinking, which make it not a circle but a triangle. The one is his eschatological consciousness, the certainty that in Christ eschatology is fulfilled and a New Reality has started. The second is the doctrine of the Spirit, which means for him that the Kingdom of God has appeared, that it is here, and there; that the New Being, in which we are, is given to us in Christ. The third point in Paul is the critical defense against legalism: justification by faith.
