The codes and creeds of Scientology were written by L. Ron Hubbard in the 1950s during the formative years of the religion. They set the guidelines for the practice and expansion of Scientology and still serve those ends today.
Included in these creeds are codes for the auditor, the supervisor, the manager and additional codes by which all Scientologists strive to live. Like Scientology, the usefulness of these principles determines their worth. Scientologists follow these precepts in applying Scientology Technology, in dealings with others and in the administration of their groups and the practice of their religion.
