This explains the proposition which frequently appears, in the Commentary on Romans and elsewhere, that man is at the same time righteous and a sinner, that the righteous man has the left foot still in sin and the right in grace.[528] In the Commentary he attacks self-complacency in the performance of good works with the cry: “Good works are not something that can please because they are good or meritorious, but because they have been chosen by God from eternity as pleasing to Himself,” words which presuppose that only the imputation matters. “Therefore,” he continues, “works do not render us good, but our goodness, or rather the goodness of God, makes us good and our works good; for in themselves they would not be good, and they are or are not good in so far as God accounts them, or does not account them good (‘_quantum ille reputat vel non reputat_’). Our own accounting or not accounting does not matter in the least. Whoever keeps this before him is always filled with fear, and waits with apprehension to see how God’s sentence will fall out. This puts an end to all that puffing up of self and quarrelling, so beloved of the proud ‘_iustitiarii_,’ who are so sure of their good works.” “Even the very definition of virtue which Aristotle gives,” he concludes, “is all wrong, as though, forsooth, virtue made us perfect and its work rendered us worthy of praise. The truth is simply that it makes us praiseworthy in our own eyes and commends our works to us; but this is abominable in God’s sight, while the contrary is pleasing to Him.”[529] As a matter of fact, Scholasticism, basing its teaching on Aristotle, considered virtue and vice as something real and objective, as qualities of the soul which adhere to it inwardly and “inform” it, i.e. impart to it a spiritual form and become part of it in the same way as material things have their special qualities, for instance, their natural colour without which they do not exist. These, as a matter of fact, were merely learned ways of expressing the fundamental truth naturally perceived by all, viz. that evil deeds and vices render a man evil, and good deeds and virtues render him good; no sane mind could conceive of a theory of imputation by which good is made evil or evil good. Luther was naturally obliged by his new theology of imputation to declare war on the older theological view of the existence of virtue and vice in the soul.[530] It was in so doing that, in his excitement, he uttered the curses above referred to (p. 209). It was no mere question of words, but of the very foundation of his new theology, a fact which makes his excitement comprehensible. As a matter of fact, by his application of the theory of imputation he was heading for a “transformation of all values” and drifting towards the admission of a “future life of good and evil” long before modern philosophy had confidently opened up a similar perspective. 6.
