But Luther, while proclaiming the impotence of man, did not fall into the opposite extreme. He says in the eighth thesis, "It follows not that the will is naturally bad, that is to say, that its nature is of the essence of evil, as the Manichees taught."[290] Originally the nature of man was essentially good; but it turned aside from goodness, that is, God, and is inclined to evil. Still its origin remains holy and glorious, and is capable, by the power of God, of regaining its original. The object of Christianity is to restore it. The gospel, it is true, exhibits man in a state of degradation and impotence, but as placed between two glories and two grandeurs,--a past glory, from which he has been precipitated, and a future glory, to which he is called. This is the truth, and man knows it to be the truth; and how little soever he thinks of it, he easily discovers that all which is told him of his actual purity, power, and glory, is only a lie, designed to cradle his pride and rock it asleep. [290] "Nec ideo sequitur quod sit naturaliter mala, id est natura mali, secundum Manichæos." (Ibid.) Nor does it therefore follow that it is naturally evil, _i.e._, of the nature of evil, according to the Manichees. Luther, in his theses, attacked not only the pretended goodness of man's will, but also the pretended light of his understanding in regard to divine things. In fact, scholasticism had exalted reason as well as the will. This theology, in the hands of some of its teachers, was, at bottom, only a species of rationalism. The propositions which we have enumerated indicate this; for they look as if directed against the rationalism of our own day. In the theses, which were the signal of the Reformation, Luther attacked the Church and the popular superstitions which to the gospel had added indulgences, purgatory, and numberless abuses. In those which we have just given he attacked the school and the rationalism which had robbed the gospel of the doctrine of the sovereignty of God, his revelation and his grace. The Reformation attacked rationalism before it attacked superstition. It proclaimed the rights of God before lopping off the excrescences of man. It was positive before it was negative. This has not been sufficiently attended to, and yet, without attending to it, it is impossible duly to appreciate the character of this religious revolution. Be this as it may, the truths which Luther thus expressed with so much energy were quite new. To maintain these theses at Wittemberg had been an easy matter. There his influence was paramount, and it would have been said that he had chosen a field of battle where he knew no combatant could appear. In offering battle in another university he gave them a greater publicity; and it was by publicity that the Reformation was effected. He turned his eyes towards Erfurt, where the theologians had shown themselves so exasperated against him.
