6 THE WORKS OF ST. AUGUSTIN.
Augustin's method in this work is (1.) The exegetical; (2.) The rational. He first deduces the doctrine of the Trinity from Scripture, by a careful collation and combination of the texts, and then defends it against objections, and illustrates it by the analogies which he finds in nature generally, and in the human mind particularly. The Scripture argument is contained in the first seven books; the rational in the last eight. The first part is, of course, the most valuable of the two. Though the reader may not be able to agree with Augustin in his interpretation of some Scripture passages, particularly some which he cites from the Old Testament, he will certainly be impressed by the depth, acumen, and accuracy with which the Latin father reaches and exhausts the meaning of the acknowledged trinitarian texts. Augustin lived in an age when the Scriptures and the Greek and Roman classics were nearly all that the student had, upon which to expend his intellectual force. There was considerable metaphysics, it is true, but no physics, and little mathematics, There was consequently a more undivided and exclusive attention bestowed upon revealed religion as embodied in the Scriptures, and upon ethics and natural religion as contained in the classics, than has ever been bestowed by any subsequent period in Christendom, One result was that scripture was expounded by scripture; things spiritual by things spiritual. This appears in the exegetical part of this treatise. Augustin reasons out of the Scriptures; not out of metaphysics or physics.
The second, or speculative division of the work, is that which will be most foreign to the thinking of some trinitarians. In it they will find what seems to them to be a philosophy, rather than an interpretation of the word of God. We shall, therefore, in this introductory essay, specify some of the advantages, as it seems to us, of the general method of defending and illustrating the doctrine of the Trinity employed by Augustin and the patristic Trinitarians.
1. Fuller justice is done to Scripture by this method. Revelation denominates the first trinitarian person the Father, the second the Son, the third the Spirit. These terms are literal, not metaphorical; because the relations denoted by them are eternally in the essence. Scripture clearly teaches that the Father is such from eternity. Consequently, '' paternity' (implied in the name Father) can no more be ascribed to the first person of the Godhead in a figurative sense, than eternity can be. For a person that isa father must be so in relation to a son. No son, no father. Consequently, an efernal Father implies an eternalSon. And the same reasoning holds true of the relation of the Father and Son to the Spirit. Theterms Father, Son, and Spirit, in the baptismal formula and the apostolic benediction, must designate primary and eternal distinctions. The rite that initiates into the kingdom of God, certainly would not be administered in three names that denote only assumed and temporal relations of God; nor would blessings for time and eternity be invoked from God under such secondary names.
Hence, these trinal names given to God in the baptismal formula and the apostolic benediction, actually force upon the trinitarian theologian, the ideas of paternity, generation, filiation, spiration, and procession. He cannot reflect upon the implication of these names without forming these ideas, and finding himself necessitated to concede their literal validity and objective reality. He cannot say that the first person is the Father, and then deny that he '' begets." He cannot say that the second person is the Son, and then deny that he is ''begotten.'' He cannot say that the third person is the Spirit, and then deny that he "proceeds" by ''spiration'' (spiritus guia spiratus) from the Father and Son. When therefore Augustin, like the primitive fathers generally, endeavors to illustrate this eternal, necessary, and constitutional energizing and activity (opera ad intra) in the Divine Essence, whereby the Son issues from the Father and the Spirit from Father and Son, by the emanation of sunbeam from sun, light from light, river from fountain, thought from mind, word
