"Healing the sick and the sinner with Truth demonstrates what we affirm of Christian Science, and nothing can substitute this demonstration. I recommend that each member of this Church shall strive to demonstrate by his or her practice, that Christian Science heals the sick quickly and wholly, thus proving this Science to be all that we claim for it." We find these words in Article XXX, Section 7, of the Manual of The Mother Church by Mrs. Eddy.
In this By-Law, our Leader emphasizes the importance of healing. In the seal on the cover of all her writings appears Christ Jesus' command (Matt. 10:8, Am. Stand. Ver.), "Heal the sick, raise the dead, cleanse the lepers, cast out demons." Thus she makes it clear that Christian Scientists are expected to prove their ability to heal. Let us ask ourselves whether we are meeting this demand, whether we are cherishing a willingness to prepare ourselves to be Christian Science practitioners if called to this great work.
What is a practitioner? A practitioner is one who heals through love and spiritual understanding. The practitioner has a conviction of the allness of God, Mind, Spirit, and of the health and perfection of man in God's image and likeness. From this point of view he sees the unreality of disease and sin.
