The Philosophical Element of Augustine’s Doctrine.
There are two elements in Augustine’s doctrine of sin: the one metaphysical or philosophical, the other moral or religious. The one a speculation of the understanding, the other derived from his religious experience and the teaching of the Holy Spirit. The one has passed away, leaving little more trace on the history of doctrine than other speculations, whether Aristotelian or Platonic. The other remains, and has given form to Christian doctrine from that day to this. This is not to be wondered at. Nothing is more uncertain and unsatisfactory than the speculations of the understanding or philosophical theories. Whereas nothing is more certain and universal than the moral consciousness of men and the truths which it reveals. And as the Scriptures, being the work of God, do and must conform their teachings to what God teaches in the constitution of our nature, doctrines founded on the twofold teaching of the Spirit, in his word and in the hearts of his people, remain unchanged from generation to generation, while the speculations of philosophy or of philosophical theologians pass away as the leaves of the forest. No man now concerns himself about the philosophy of Origen, or of the new Platonists, or of Augustine, while the language of David in the fifty-first Psalm is used to express the experience and convictions of all the people of God in all ages and in all parts of the world.
The metaphysical element in Augustine’s doctrine of sin arose from his controversy with the Manicheans. Manes taught that in was a substance. This Augustine denied. With him it was a maxim that “Omne esse bonum est.” But if esse (being) is good, and if evil is the opposite of good, then evil must be the opposite of being, or nothing, i.e., the negation or privation of being. Thus he was led to adopt the language of the new Platonists and of Origen, who, by a different process, were brought to define evil as the negation of being, as Plotinus calls it, στέρησις τοῦ ὄντος; and Origen says, πᾶσα ἡ κακία οὐδέν ἐστιν, and evil itself he says is ἐστερῆσθαι τοῦ ὄντος. In thus making being good and the negation of being evil, Augustine seems to have made the same mistake which other philosophers have so often made, — of confounding physical and moral good. When God at the beginning declared all things, material and immaterial, which He had made, to be very good, He simply declared them to be suited to the ends for which they were severally made. He did not intend to teach us that moral goodness could be predicated of matter or of an irrational animal. In other cases the word good means agreeable, or adapted to give pleasure. In others again, it means morally right. To infer from time fact that everything which God made is good, or that every esse is bonum, that therefore moral evil being the negation of good must be the negation of being, is as illogical as to argue that because honey is good (in the sense of being agreeable to the taste) therefore worm-wood is bad, in the sense of being sinful. Although Augustine held the language of those philosophers who, both before and since, destroy the very nature of sin in making it mere limitation of being, yet he was very far from holding the same system. (1.) They made sin necessary, as arising from the very nature of a creature. He made it voluntary. (2.) They made it purely physical. He made it moral. With him it includes pollution and guilt. With them it included neither. (3.) With Augustine this negation was not merely passive, it was not the simple want of being, it was such privation as tended to destruction. (4.) Evil with Augustine, therefore, as was more fully and clearly taught by his followers, was not mere privation, nor simply defect. That a stone cannot see, involves the negation of the power of vision. But it is not a defect, because the power of vision does not belong to stones. Blindness is a defect in an animal, but not sin. The absence of love to God in a rational creature is sin, because it is the absence of something which belongs to such a creature, and which he ought to have. In the true Augustinian sense, therefore, sin is negation only as it is the privation of moral good, — the privatio boni, or as it was afterwards generally expressed, a want of conformity to the law or standard of good.
Augustine’s Reasons for making Sin a Negation.
In thus making sin negation, Augustine had principally two ends in view. (1.) To show that sin is not necessary. If it were something existing of itself, or something created by the power of God, it was beyond the power of man. He was its victim, not its author. (2.) He desired to show that it was not due to the divine efficiency. According to his theory of God’s relation to the world, not only all that is, every substance, is created and upheld by l rod, but all activity or power, all energy by which positive effects are produced, is the energy of God. If sin, therefore, was anything in itself, anything more than a defect, or a want of conformity to a rule, God must be its author. He, therefore, took such a view of the psychological nature of sin, that it did not require an efficient, but as he often said only a deficient cause. If a man, to use the old Augustinian illustration, strike the cords of an untuned harp, he is the cause of the sound but not of the discord. So God is the cause of the sinner’s activity but not of the discordance between his acts and the laws of eternal truth and right.1
