Christian Science is logical. Christian Science is based firmly on the premise that God is All-in-all, that He made everything that exists, and that, therefore, there can be no reality in anything which is not good, perfect, and eternal.
When Mary Baker Eddy, the Discoverer and Founder of Christian Science, more than sixty years ago declared that matter has neither substance nor reality, her statement was startling and incredible to a conventional world which believed matter to be both cause and effect. Yet it is a simple, inevitable deduction from the premise that a perfect, omnipotent God, Spirit, maintains His perfect spiritual creation, even though on every side material sense beholds imperfection and impermanence. Were matter, which seems to grow and dissipate, change and deteriorate, real, God would not be a flawless creator nor an errorless governor of the universe. To be consistent, one has to establish concepts of God and of matter different from those held in mortal belief.
In this age proof that the man and the universe of God's creation are spiritual, not material, has been presented in wonderful healings of the sick and sinful by Mrs. Eddy and her followers. The truth which Christ Jesus declared would make men free has again been made known by one who understood his sayings and knew that the Master meant all that he said.
