 Luther was able to develop this new position further in another disputation, this time held in Heidelberg in 1518, where thanks to the controversy unleashed by the Ninety-five Theses, he was invited by Staupitz to present his theological ideas to the triennial assembly of the German Augustinians. In this Heidelberg Disputation, Luther continued his assault on “works righteousness”, and developed further an associated attack on free will, while he also presented a contrast that was to prove fundamental to his thinking, between a “theology of glory” and a “theology of the cross”. He associated the former with his opponents, and himself with the latter, arguing that it is only through despair at our failure to gain salvation for ourselves that we are truly made ready to be given salvation through grace. It now became clear to his audience that Luther (who to mark this change in perspective had just previously started signing himself “Luther” in short for “eleutherios” or the “freed one”, instead of his family’s actual name of “Luder”) was attempting not merely to confront the Church on the issue of indulgences, but also to question what he perceived to be its misguided theological outlook.
