How did Mary Baker Eddy’s teachings describe the relationship between God, Spirit, and matter?

Mary Baker Eddy’s teachings define the relationship between God, Spirit, and matter by asserting that Spirit is the sole reality of existence, while matter is an illusion or a false sense of reality.12

In her view, God is omnipotent and infinite, and life, will, and mind originate from Spirit rather than from matter. Eddy argued that the traditional belief that God created matter is a fallacy, as it would imply that God is responsible for suffering and evil. Instead, she taught that what humans perceive as the material world is a subjective state evolved from mortal thought, which serves to obscure the true spiritual reality.12

Consequently, Christian Science emphasizes the "allness of Soul, Spirit, and the nothingness of matter". Redemption is understood as a process of overcoming the limitations of the mortal state by gaining "the mind of Christ," which involves looking beyond material appearances to recognize humanity's true spiritual status. Through this spiritual understanding, sin, disease, and death are revealed to be unreal, as they are predicated on the false belief that life is rooted in matter.21
