It is highly probable that the bewildered soul of the young Augustinian greedily lent an ear to such ideas, and laboured to make them meet his own needs. The doubts as to predestination which tormented him were certainly not thereby diminished, but rather increased. How could the idea of an arbitrary God have been of any use to him? In all likelihood the apprehensiveness and obscurity which colours his idea of God, in the Commentary on Romans, was due to notions imbibed by him in his school. Luther was later on to express this conception in his teaching regarding the “_Deus absconditus_,” on whom, as the source of all predestination (even to hell), we may not look, and whom we may only timidly adore. Already in the Commentary referred to he teaches the absolute predestination to hell of those who are to be damned, a doctrine which no Occamist had yet ventured to put forward. Among the other points of contact between Luther’s teaching and Occamism, or Nominalism, we may mention, as a striking example, his denial of Transubstantiation, which he expressly associates with one of the theses of the Occamist d’Ailly. Here his especial hatred of the school of St. Thomas comes out very glaringly. Luther himself confesses later how the Occamist school had led him to this denial.[400] When studying scholastic theology he had read in d’Ailly that the mystery of Christ’s presence in the Sacrament of the Altar would be much more comprehensible could we but assume that He was present _with_ the bread, i.e. without any change of substance, but that this was impossible owing to the unassailable contrary teaching of the Church on Transubstantiation. The same idea is found in Occam, but of this Luther was unaware. Luther criticises d’Ailly’s appeal to the Church, and then proceeds: “I found out later on what sort of Church it is which sets up such a doctrine; it is the Thomistic, the Aristotelian. My discovery made me bolder, and therefore I decided for Consubstantiation. The opinions of the Thomists, even though approved by Pope or Council, remain opinions and do not become articles of faith, though an angel from heaven should say the contrary; what is asserted apart from Scripture and without manifest revelation, cannot be believed.”[401] Yet in point of fact the term “_Transsubstantiatio_” had been first used in a definition by the Œcumenical Lateran Council of 1215 to express the ancient teaching of the Church regarding the change of substance. According to what Luther here says, St. Thomas of Aquin (whose birth occurred some ten years later) was responsible for the introduction of the word and what it stood for, in other words for the doctrine itself. A little later Luther solemnly reaffirmed that “Transubstantiation is purely Thomistic” (1522).[402] “The Decretals settled the word, but there is no doubt that it was introduced into the Church by those coarse blockheads the Thomists” (1541).[403] Hence either he did not know of
