According to the ancient magical conception of God in the scheme of the universe, evil is the inevitable contrast and complement of good. God permits the existence of the shadow in order that it may intensify the purity of the light. He has created both and they are thus inseparable, the one being necessary to and incomprehensible without the other.
The very idea of goodness loses its meaning if considered apart from that of evil—Gabriel is a foil to Satan and Satan to Gabriel. The dual nature of the spiritual world penetrates into every department of life, material and spiritual. It is typified in light and darkness, cold and heat, truth and error, in brief, the names of any two opposing forces will serve to illustrate the primary law of nature—namely, the continual conflict between the positive or good and the negative or evil.
For a scriptural illustration of this point, the story of Cain and Abel can be used. The moral superiority of his brother is at first irksome to Cain, finally intolerable. He murders Abel, thus bringing on his own head the wrath of God and the self-punishment of the murderer. For in killing Abel, Cain has done himself harm. Cain has not done away with Abel's superiority, but has added to himself a burden of guilt that can end only by much suffering.
Suffering is shown in the Judaeo-Christian scriptures to be one means evil is overcome by good. Cain reappears in the story of the prodigal son, who after deprivation and suffering is restored to his father who forgives him fully and freely.
It is believed that the possibility of sin and error is consistent with and inseparable from life. The great sinner is a more vital being than the colorless character, because having greater capacity for evil he has also greater capacity for good, and in proportion to his faults so will his virtues be when he turns to God. "There is more joy in heaven over one sinner that repenteth than over ninety and nine just persons," because more force of character, more power for good or evil is displayed by the sinner than by the feebly correct. And that power is the most precious thing in life. The apostle Paul specifically rejected this approach to understanding sin and redemption in Romans 6: 1-2.
This dual law of right and wrong, two antagonistic forces, is designated by the term "duad." It is the secret of life and the revelation of that secret means death. This secret is embodied in the myth of the Tree of Knowledge in Genesis. At death the discord will be resolved, but not until then.
From the duad is derived the triad based on the doctrine of the Trinity. Two forces producing equilibrium, the secret of nature, are designated by the duad, and these three—life, good, and evil—constitute one law. By adding the conception of unity to the triad the tetrad is produced, the perfect number of four, the source of all numerical combinations.
According to orthodox theology there are three persons in God, Father, Son and Holy Ghost, and these three form one Deity. In occult speculations, three and one make four, the fourth reality being the unity required to explain the Three. Hence, it is suggested, in many languages (most notably Hebrew), the name of God is symbolized by four letters. Again, two affirmations make two negations either possible or necessary. According to the Kabalists the name of the Evil one consisted of the same four letters spelled backward, signifying that evil is merely the reflection or shadow of good—"The last reflection or imperfect mirage of light in shadow." Everything exists in light or darkness, good or evil, and exists through the tetrad. The triad or trinity, then, is explained by the duad and resolved by the tetrad.
Such occult interpretations of God echo the ancient mysticism such as the Eastern religion of Hinduism, where the pairs of opposites like good and evil are regarded as twin poles of a larger reality, where anthropomorphic concepts of God the creator are considered legal fictions for a divine infinity, beyond time, space, and causality.
