“Luther’s new insights contained already the marrow of his mature theology. The salient ideas were present in the lectures on Psalms and Romans from 1513 to 1516. What came after was but commentary and sharpening to obviate misconstruction. The center about which all the petals clustered was the affirmation of forgiveness sins through the utterly unmerited grace of God made possible by the cross of Christ, which reconciled wrath and mercy, routed the hosts of hell, triumphed over sin and death, and by the resurrection manifested that power which enables man to die to sin and rise to newness of life. This was of course the theology of Paul, heightened, intensified, and clarified. Beyond these cardinal tenets Luther was never to go” (Roland Bainton, Here I Stand, 68).
