The Code of Scientologist by L. Ron Hubbard (1969), selections :

As a Scientologist, I pledge myself to the Code of Scientology for the good of all.

1. To keep Scientologists, the public and the press accurately informed concerning Scientology, the world of mental health and society.

2. To use the best I know of Scientology to the best of my ability to help my family, friends, groups and the world.

[ . . ]

11. To actively decry the suppression of knowledge, wisdom, philosophy or data which would help mankind.

12. To support the freedom of religion.

13. To help Scientology orgs and groups ally themselves with public groups.

14. To teach Scientology at a level it can be understood and used by the recipients.

15. To stress the freedom to use Scientology as a philosophy in all its applications and variations in the humanities.

16. To insist upon standard and unvaried Scientology as an applied activity in ethics, processing and administration in Scientology organizations.

17. To take my share of responsibility for the impact of Scientology upon the world.

[ . . ]

20. To make this world a saner, better place.

Note these being selections is of course a non-optimum solution (the copyright issue being also present). The reader is advised by me to study the entirety of the Code in the publications broadly available.

Re # 14 : personally, I am not engaging in teaching Scientology (it is the # 1, then the rest, which I here apply as an individual).

The # 14 is of interest to those persons who are being taught the subject. As a personal observation I would only mention that I have found the fundamentals by L. Ron Hubbard relatively simple and any expositions of the subject by anybody, if not able to refer to the fundamentals, can be presumed in violation of this Code. — (WPT)
