Juliette Lewis: A Unique Perspective
Actress Juliette Lewis identifies as both a Christian and a Scientologist, a combination that reflects her open-minded approach to spirituality. In a 2010 interview, she explained, "There’s so much misunderstanding because people don’t realize that you can practice Scientology alongside another religion. It’s not about dogma; it’s about tools for living, understanding yourself and others, and fostering compassion. It’s practical, common-sense guidance that has nothing to do with the myths that circulate around it. You could be a Jewish Scientologist, a Buddhist Scientologist, or even a Christian Scientologist like me." Juliette's viewpoint highlights the flexibility she sees within Scientology's teachings.
