When St. Paul elsewhere describes more narrowly the nature of justifying faith (a fact to which both the Fathers and the theologians draw attention), he is quite emphatic in asserting that the sinner is not admitted by God to grace and made partaker of the heavenly promises merely by virtue of a dead faith, but by a real, supernatural faith which works by charity (Gal. v. 6). This in previous ages had been rightly understood to mean not merely an acceptance of the Word of God and the intimate persuasion of the remission of one’s sins, but a faith enlivened by grace with charity. In confirmation of this, other well-known passages of the New Testament were always quoted: “Wilt thou know, O vain man, that faith without works is dead?” “Do you see that by works a man is justified; and not by faith only?” “For even as the body without the spirit is dead: so also faith without works is dead.” “Labour the more that by good works you may make sure your calling and election.”[818] Some important disputations which the youthful University Professor held on theses and “paradoxa” formulated by himself prove how his teaching was taking ever deeper root at Wittenberg and elsewhere. The story of these disputations casts light on his peculiar tactics, viz. to meet every kind of opposition by still more forcibly and defiantly advancing his own propositions. 2. Disputations on man’s powers and against Scholasticism (1516-17) In September, 1516, Luther arranged for a remarkable Disputation to be held at Wittenberg by Bartholomew Bernhardi of Feldkirchen, in Swabia, on the occasion of the latter’s promotion to be Lecturer on the Sentences. From a confidential letter of Luther’s to Johann Lang, Prior at Erfurt, we learn some particulars as to the motive which determined the choice of the theses, which latter are still extant. From this we see that the Disputation was held on account of those who “barked” at Luther’s lectures. “In order to shut the mouths of yelping curs, and at the same time to let the opinion of others be heard,” the theses on man’s absolute inability to do what is good were purposely worded in a most offensive form. This Disputation brought over Amsdorf, hitherto an opponent, to Luther’s side. Amsdorf sent a copy of the theses to Erfurt in order to elicit the opinion of the professors there. But, fearing lest the storm he foresaw might be directed against Luther, he deleted the superscription bearing his name (“_Sub eximio viro Martino Luthero Augustiniano_,” etc.). At the Disputation Luther presided, a fact which is all the more significant when we remember that he was not at that time Dean.
