To confirm the doctrinal points of the other kind, philosophical proofs may be employed — not indeed because it were necessary, as though theology could not prove them from its own principle, but for the sake of abundance, so that it may become clear that not only the light of grace, but also the light of nature, can attain them to some degree; nor in the first place, as if the greatest force of proof lay in those philosophical arguments, but in a subordinate one. The refutative or elenctic use consists in the contesting and refuting of doctrinal points, in which one must proceed thus: false and erroneous doctrines are first to be refuted from theology's own principle, namely from Holy Scripture, which is the proper, chief, and effective refutation; after that, philosophical grounds may also be added, in order to show that the false dogma conflicts not only with the light of grace but also with the light of nature — which is a secondary form of proof, less principal, and, without the former, wholly ineffective. To the refutative use belongs also this, that one may weaken the opponents' proofs by means of instances (examples brought forward in refutation) drawn from nature itself. Thus Augustine, when the Arians say that what is begotten cannot be of the same duration as that from which it is begotten, and that therefore the Son cannot be co-eternal with the Father, rightly sets against this the emanation of rays, which is of the same duration as the sun." "Manifold is the use of philosophy in theology, but manifold too, and indeed exceedingly pernicious, is its abuse in the same; of this we will treat in such a way as to show how philosophy, in its organic, constructive, and refutative use, is turned into abuse. In the organic use one abuses philosophy, 1. when one holds that the training of the mind attained through the study of philosophy is a source (principium) of saving faith and has an effective influence on the inward illumination of the Holy Spirit. Thus (the Reformed) Keckermann writes in his System of Theology, Bk. 1, ch. 4, p. 57: "God wills to kindle the light of the Holy Spirit in the understanding of men through those two wholly different disciplines, metaphysics and logic." But that effect — the divine, inward, and spiritual illumination — is nowhere in Scripture ascribed to the means of philosophy, but to the revealed Word alone. Ps. 19:9, 119:105, 2 Peter 1:19. The same Keckermann writes in his Philosophical Preliminaries, Bk. 1, ch. 4, p. 80: "Through philosophy piety, service, reverence, and the invocation of God are awakened in us." But true piety, etc., cannot exist without knowledge of the Mediator, Christ, which philosophy cannot attain through its own researches. John 5:23, 14:6. To this belongs the error of Zwingli, Bullinger, Andradius, and others, who
