a religion and system of healing founded by Mary Baker Eddy in 1866, emphasizing the belief that a thorough spiritual understanding of God as the all-powerful source of all that is good and true can destroy sin, sickness and the like without material aid. The members of this religion denies the reality of the material world, arguing that sin and illness are illusions to be overcome by the mind. —SHSBC Binder 3 Approved Glossary
