Spiritual but not religious?

Author Anne Rice said last week that she was 'quitting Christianity:' The once-lapsed Catholic wrote that she was could no longer accept her religion's teachings on homosexuality, feminism, politics and birth control.

"In the name of Christ, I quit Christianity and being Christian," Rice announced on her facebook page.

I have a question for you.  Can you leave religion and keep Christ? Can you be spiritual without being religious?
