And even the material use we reject only with respect to those concepts which are drawn solely from revelation. But our old teachers have written better on this than we are able to do. We will therefore let them speak. Thus, for example, Johann Gerhard writes: "The use of philosophy in theology is threefold: an organic use (serving as a tool), a constructive use (serving to prove), and a refutative use (serving to refute). The organic use extends the furthest; for the sake of doctrinal presentation it can be reduced to certain main topics; but in order to understand the matter rightly, we must first set forth the division of the philosophical sciences. They are divided, namely, into instrumental and real philosophy. To instrumental philosophy belong logic and rhetoric (grammar belongs to the science of language); to real philosophy belong, in part, theoretical sciences such as metaphysics, physics, and mathematics, and in part practical ones, such as ethics, politics, and economics. 1. As regards all the parts of philosophy taken together, both the real and the instrumental in general, we say that knowledge of them awakens, sharpens, and prepares the mind of man, and gives him the aptitude to proceed more unhindered and with less effort in every study of the higher disciplines — a preparatory benefit which they render also to the future theologian. 2. As regards the individual parts of real philosophy in particular, we say that knowledge of them is useful to theology in the explanation of certain terms (terminorum). Theology, however, makes use of a twofold kind of terms; some are found according to the letter in Scripture, and these are called biblical; others have been adopted by ecclesiastical writers and teachers, and are found not according to the letter, but according to the sense, in Scripture, and are therefore called ecclesiastical. In each of the two kinds there occur some for whose more precise explanation philosophy contributes something. Thus the words thing, good, true, perfect, finite, infinite, person, existence, essence, actuality, possibility, and so forth, are terms drawn from metaphysics, and hence a knowledge of metaphysics can also contribute something to their explanation. Time, place, heaven, earth, sea, fire, snow, hail, rain, faculties of the soul, and so forth, are terms of physics, and hence the theologian derives their explanation from physics.
