Church Organizations Ample. SECTION 15. Members of this Church shall not unite with organizations which impede their progress in Christian Science. God requires our whole heart, and he supplies within the wide channels of The Mother Church dutiful and sufficient occupation for all its members. Joining Another Society. SECTION 16. It shall be the duty of the members of The Mother Church and of its branches to promote peace on earth and good will toward men; but members of The Mother Church shall not hereafter become members of other societies except those specified in the Mother Church Manual, and they shall strive to promote the welfare of all mankind by demonstrating the rules of divine Love. Forbidden Membership. SECTION 17. A member of The First Church of Christ, Scientist, in Boston, Mass., shall not be a member of any church whose Readers are not Christian Scientists and members of The Mother Church. Officious Members. SECTION 18. A member of The Mother Church is not entitled to hold office or read in branch churches of this denomination except by invitation. Legal Titles. SECTION 19. Students of Christian Science must drop the titles of Reverend and Doctor, except those who have received these titles under the _laws_ of the _State_. Illegal Adoption. SECTION 20. No person shall be a member of this Church who claims a spiritually adopted child or a spiritually adopted husband or wife. There must be legal adoption and legal marriage, which can be verified according to the laws of our land. Use of Initials "C.S." SECTION 21. A member of The Mother Church shall not place the initials "C.S." after his name on circulars, cards, or leaflets, which advertise his business or profession, except as a Christian Science practitioner. Practitioners and Patients. SECTION 22. Members of this Church shall hold in sacred confidence all private communications made to them by their patients; also such information as may come to them by reason of their relation of practitioner to patient. A failure to do this shall subject the offender to Church discipline. A member of The Mother Church shall not, under pardonable circumstances, sue his patient for recovery of payment for said member's practice, on penalty of discipline and liability to have his name removed from membership. Also he shall reasonably reduce his price in chronic cases of recovery, and in cases where he has not effected a cure. A Christian Scientist is a humanitarian; he is benevolent, forgiving, long-suffering, and seeks to overcome evil with good. Duty to Patients. SECTION 23. If a member of this Church has a patient whom he does not heal, and whose case he cannot fully diagnose, he may consult with an M. D. on the anatomy involved. And it shall be the privilege of a Christian Scientist to confer with an M. D. on Ontology, or the Science of being.
