Here's a description of the IAS, from this site:
"The IAS is the official membership organization of Scientology, the most vital movement on Earth today.
"A Scientologist is defined as “essentially one who betters the conditions of himself and the conditions of others by using Scientology technology.”
"The IAS is made up of individual Scientologists who desire to change conditions on this planet for the better. Its purpose is:
"To unite, advance, support and protect the Scientology religion and Scientologists in all parts of the world, so as to achieve the aims of Scientology as originated by L. Ron Hubbard."
