It was a big affairs with over 1,000 people. I didn't attend unfortunately, however, I heard it was a great evening.
Here's an article about it.
HOLLYWOOD — The Church of Scientology Celebrity Centre International hosted its 37th Anniversary Gala in Hollywood on Saturday, August 5th. The guest list included many of the Church's well-known members, including John Travolta, Kelly Preston, Jenna Elfman, Leah Remini, Giovanni Ribisi, Jason Dohring, Anne Archer, Sofia Milos and Nancy Cartwright (voice of Bart Simpson).
Legendary guest performer Chaka Kahn entertained the more than 1100 guests including parishioners of the Church, local and federal government officials and community leaders.
Guests were also treated to a preview of 30 new TV public service announcements — each illustrating one of the 30 articles of the United Nations' Universal Declaration of Human Rights. Through these audio-visual presentations and other educational tools, Human Rights Department of the Church of Scientology International, in partnership with Youth for Human Rights International, seeks to reach millions of people to raise awareness of fundamental human rights and bring about global change.
Its popularity in the arts mirrors the overall growth of the Scientology religion, with 10 million members in over 150 countries. Its rapid expansion is word-of-mouth driven, due to the religion's practical principles that are used to improve conditions in life.
The Church of Scientology Celebrity Centre in Hollywood was founded in 1969. Other Celebrity Centres are located in cultural centers around the world including New York, Paris, Nashville, Vienna, Florence and London.
In keeping with Scientology founder L. Ron Hubbard's words from 1951, "A culture is only as great as its dreams, and its dreams are dreamed by artists," these Celebrity Centres are the arts and cultural branch of the Scientology religion and as such work with those whose broad visions for social enhancement are the catalyst for positive change in society. Celebrity Centres, like all churches of Scientology worldwide, are open to the public.
