The Protestant scholar last mentioned has dissected the Commentary on the Psalms in detail; particularly did he examine its connection with the philosophical and mystical system sometimes designated as Augustinian Neo-Platonism.[173] It may be left an open question whether his complicated researches have succeeded in proving that in the Commentary—interpreted in the light of some of the older sermons and the marginal glosses in the Zwickau books—Luther’s teaching resolves itself into a “somewhat loose and contradictory mixture of four elements,” namely, Augustinian Neo-Platonism, an Augustinian doctrine on sin and grace, a trace of scholastic theology, and some of the mysticism of St. Bernard.[174] His researches and his comparison of many passages in the Commentary on the Psalms with the works of Augustine, especially with the “_Soliloquia_” and the book “_De vera religione_,” have certainly shown that Luther was indebted for his expressions and to a certain extent for his line of thought, to those works of Augustine with which he was then acquainted. He had probably been attracted by the mystical tendency of these writings, by that reflection of Platonism, which, however, neither in St. Augustine’s nor in Luther’s case, as Hunzinger himself admits, involved any real acceptance of the erroneous ideas of the heathen Neo-Platonism. Luther was weary of the dry Scholasticism he had learned at the schools and greedily absorbed the theology of the Bishop of Hippo, which appealed far more to him, though his previous studies had been insufficient to equip him for its proper understanding. His own words in 1532 express his case fairly accurately. He says: “In the beginning I devoured rather than read Augustine.”[175] In a marginal note on the Sentences of Peter Lombard he speaks, in 1509, of this Doctor as “_numquam satis laudatus_,” like him, he, too, would fain send the “_moderni_” and that “fabulator Aristoteles” about their business.[176]
