Spiritual understanding of the Christ, God's divine idea, which is invincible and thus invulnerable to all the evils of mortality, enables us to challenge scientifically and to destroy the errors of material sense. Christian Science explains that it is material sense, not man, which appears to experience the false claims of sin, sickness, and death. The recognition of the illusory nature of material sense, or mind in matter with its accompanying sin and suffering, helps us to free ourselves from the enslaving beliefs of mortal mind. The powerlessness of erroneous belief is clearly perceived by thought which knows the omnipotence and omnipresence of immortal Mind, God.
Christian Science heals sin and disease on the basis of the allness of God and His ever-present manifestation, the Christ, Truth, which reveals man's perfect spiritual individuality. Science teaches that individual man is the individualized reflection of Mind, God. In "Science and Health with Key to the Scriptures" Mary Baker Eddy writes (p. 317), "The understanding of his spiritual individuality makes man more real, more formidable in truth, and enables him to conquer sin, disease, and death."
Spiritual man, the real man of God's creating, who is perfect, sinless, and wholly free from fear and disease, is most apparent to the human thought which is becoming spiritualized through Christian Science. This Science corrects the mortal picture which portrays humanity as vainly attempting to resist evil but eventually succumbing to its relentless demands. It relies on Scriptural authority. It claims that man, as a son of God, is spiritual, and that he includes limitless capabilities and ability by reflection. In Paul's epistle to the Romans we read (8:35-39):"Who shall separate us from the love of Christ? shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? . . . Nay, in all these things we are more than conquerors through him that loved us. For I am persuaded, that neither death, nor life, nor angels, nor principalities, nor powers, nor things present, nor things to come, nor height, nor depth, nor any other creature, shall be able to separate us from the love of God, which is in Christ Jesus our Lord."
