A new religion based off the sappy Mormon-written Twilight series. It has no tax exempt status, very few members, a prayer ripped off from the Lord's Prayer, and the majority of the congregation are virginal girls (not of the hot kind, either).

Basically, cullenism is basically the Church Of Scientology except, would you believe it - their members are far more insane, you have to replace aliens with "sexeh vampires OMG TEAM EDWARD YAAAY!" and instead of being founded by a failure of a science-fiction writer, it's based off the masturbation fodder of a Mormon homemaker.
