Not Christian/Not Science.
“Man” is Mary Baker Eddy
She started her first church in Boston, Mass. and taught that sickness is an illusion that can be treated by prayer alone.
This religion has a metaphysical healing focus, and promote that “Belief in sin is punished so long as the belief lasts.”
They also believe in a Father/Mother God.
Christian Science teaches that God—Father-Mother of all—is completely good and wholly spiritual and that all God’s creation, including the true nature of every person, is the flawless spiritual likeness of the Divine. Since God’s creation is good, evils such as disease, death, and sin cannot be a part of fundamental reality. Rather, these evils are the result of living apart from God.
