The description of man as incorporeal, which Christian Science declares him to be, may not appeal to the worldly-minded, but it is a word that challenges the thinker. The fact is that both God and man are incorporeal—without physical bodies—and when the sinful and the suffering grasp this truth, they find relief from their troubles.
Great numbers of Christians admit readily that God is incorporeal Spirit, invisible to the senses, but they still believe that man is flesh. And they believe this regardless of the Biblical revelation that man is the likeness of Spirit. That one's identity can be distinct and individual and yet have no connection with matter is a fundamental point in the theology of Christian Science. And one does not need to die, as the world believes, in order to be conscious of his incorporeal self. Little by little he can prove that the flesh is an illusion, which must eventually be dispelled by the truth that man's substance is Spirit. In the Science of being there is no corporeality. Man, God's likeness, moves freely in the realm of Spirit, unhampered by flesh, never chained to it.
By his resurrection, Jesus demonstrated the power of Spirit to protect and restore health to the physical body. He even showed that death does not destroy the material sense of body. But by his ascension, Jesus proved that there is a spiritual body, a real body, which is the embodiment of Life and characterized by Life's immortal qualities.
