Summary and Keywords

In the debate on Luther’s Reformatory Discovery two elements come together: the systematic question of how to determine the essential content of reformatory theology, that is, the core of Reformation itself, and the historical question of the point in his life at which Luther reached this insight. The debate arose first in the late 19th century, when the essence of Protestantism was brought into question and scholars tried to find an answer in the writings of Luther himself.

This historical and methodological conjunction leads to different results concerning both the religious content of the discovery and the date when Luther discovered it. Two main answers have been given. The first supposes that it is the logical structure of self-annihilation and divine affirmation that is specifically reformatory. Luther came to this insight during his first lecture on Psalms, about 1514. This means that he certainly knew what his new theology contained when the indulgences controversy broke out. The second theory underscores that Luther had to establish a kind of outward kerygmatic reality in order to make the inner conflict and contradiction of sentiments acceptable. He reached this position only in 1518, that is, after the beginning of the controversy over indulgences in 1517. Therefore, the final development of Luther’s reformatory insight took place in the confrontation with the ecclesiastical powers of his day.

For many years the debate focused upon a late text by Luther, namely, the preface of the first volume of his Latin works in 1545. It has to be admitted that Luther offered there his own recollection of the beginning of his new theology. But he did so quite briefly, concentrating only on the notion of iustitia passiva. This is a proper term for the content of the reformatory insight, but Luther did not fully explain the spiritual and practical context. Therefore, one must imagine that the Reformatory Discovery came about through a longer process of theological reflection, including its biblical, conceptual, spiritual, and ecclesial consequences. It is significant that the conflict with the Roman Church came up exactly when Luther stressed the externality of God’s Word for establishing the inner status of humankind before God. The church can only be the medium, not the subject, of salvation. And the correspondence to God’s Word means quite simply faith, that is, the acceptance of being accepted by God.

One must reckon here with a process that began with Luther’s first lectures in 1513 and came to an end by 1520. Luther’s “On the Freedom of a Christian” of 1520 clearly shows his reformatory discovery fully established.
