To represent the quest for spiritual freedom and the orthodox practice of the religion, Churches of Scientology use symbols which represent various aspects of the religion. The Scientology cross symbolizes the eight dynamics and the triumph of the spirit. The ARC triangle represents the relationship between Affinity, Reality and Communication. In the “S” and double triangle, the “S” stands for Scientology; the top triangle is the KRC triangle, Knowledge-Responsibility-Control, and the bottom triangle is the ARC triangle. The Dianetics symbol is a triangle divided into four segments which represent growth and life on the first four dynamics. The OT symbol represents the state of Operating Thetan, a being able to operate free of the encumbrances of the physical universe.

The words Dianetics, Scientology, and other words and symbols associated with the religion are registered as trademarks and service marks around the world. Each Scientology church and mission enters into a covenant with the Mother Church which allows them to use these marks, provided the Church or mission precisely adheres to the Scripture.
Thus, when a symbol associated with the Scientology religion is displayed in connection with the ministry of religious services, those participating in the services are assured that they are being ministered in exact accordance with the Scientology Scripture. In this way they can know with certainty that they are on the true path to spiritual freedom.
