The first theory in the order of time, apart from the primitive doctrine of the Bible, as to the origin and nature of sin, is the dualistic, or that which assumes the existence of an eternal principle of evil. This doctrine was widely disseminated throughout the East, and in different forms was partially introduced into the Christian church. According to the doctrine of the Parsis this original principle was a personal being; according to the Gnostics, Marcionites, and Manicheans, it was a substance, an eternal ὕλη or matter. Augustine says, “Iste [Manes] duo principia inter se diversa atque adversa, eademque æterna et coæterna, hoc est semper fuisse, composuit: duasque naturas atque substantias, boni scilicet et mali, sequens alios antiquos hæreticos, opinatus est.”1 These two principles are in perpetual conflict. In the actual world they are intermingled. Both enter into the constitution of man. He has a spirit (πνεῦμα) derived from the kingdom of light; and a body with its animal life (σῶμα and ψυχή) derived from the kingdom of darkness. Sin is thus a physical evil; the defilement of the spirit by its union with a material body; and is to be overcome by physical means, i.e., by means adapted to destroy the influence of the body on the soul. Hence the efficacy of abstinence and austerities.2
This theory obviously is: (1.) Inconsistent with Theism, in making something out of God eternal and independent of his will. He ceases to be an infinite Being and an absolute sovereign. He is everywhere limited by a coeternal power which He cannot control. (2.) It destroys the nature of sin as a moral evil, in making it a substance, and in representing it as inseparable from the nature of man as a creature composed of matter and spirit. (3.) It destroys, of course, human responsibility, not only by making moral evil necessary from the very constitution of man, and by referring its origin to a source, eternal and necessarily operative; but by making it a substance, which destroys its nature as This theory is so thoroughly anti-theistic and anti-Christian, that although long prevailing as a heresy in the Church, it never entered into any living connection with Christian doctrine.
Sin regarded as a mere Limitation of Being.
The second anti-Christian theory of the nature of sin is that which makes it a mere negation, or limitation of being. Being, substance, is good. “Omne quod est, in quantum aliqua substantia est, et bonum [est],”3 says Augustine. God as the absolute substance is the supreme good. The absolute evil would be nothing. Therefore the less of being, the less of good; and all negation, or limitation of being is evil, or sin. Spinoza4 says, “Quo magis unusquisque, suum utile quærere, hoc est suum esse conservare conatur et potest, eo magis virtute præditus est; contra quatenus unusquisque suum utile, hoc est suum esse conservare negligit, eatenus est impotens.” In his demonstration of that proposition he makes power and goodness identical, potentia and virtus are the same. Hence the want of virtue, or evil, is weakness, or limitation of being. Still more distinctly, does Professor Baur of Tübingen, present this view of the nature of sin.5 He says, “Evil is what is finite; for the finite is negative; the negation of the infinite. Everything finite is relatively nothing; a negativity which, in the constant distinction of plus and minus of reality, appears in different forms.” Again, “If freedom from sin is the removal of all limitation, so is it clear, that only an endless series of gradations can bring us to the point where sin is reduced to a vanishing minimum. If this minimum should entirely disappear, then the being, thus entirely free from sin, becomes one with God, for God only is absolutely sinless. But if other beings than God are to exist, there must be in them, so far as they are not infinite as God is, for that very reason, a minimum of evil.” The distinction between good and evil, is, therefore, merely quantitative, a distinction between more or less. Being is good, the limitation of being is evil. This idea of sin lies in the nature of the Pantheistic system. If God be the only substance, the only life, the only agent, then He is the sum of all that is, or, rather all that is, is the manifestation of God; the form of his existence. Consequently, if evil exists it is as much a form of the existence of God as good; and can be nothing but imperfect development, or mere limitation of being.
