Ja Rule's background in the Jehovah's Witnesses is mentioned in a number of interviews, including an October 31, 2003 interview with MTV (http://www.mtv.com/news/articles/1480118/20031031/story.jhtml), in which "Ja Rule and Minister Farrakhan discuss Ja's upbringing as a Jehovah's Witness..."
See also his May 20, 2002 interview with Jet magazine (http://www.findarticles.com/cf_dls/m1355/22_101/87210858/p1/article.jhtml): "The son of Debra Atkins, a single mother who worked in health care and reared her only child as a Jehovah's Witness, Ja Rule grew up knowing that he wanted to be somebody well seen."
From AskMen.com (http://www.askmen.com/toys/interview/13b_ja_rule_interview.html):
Q: Is it true you were raised as a Jehovah's Witness? How was this experience and how has it shaped you as a grown man?
A. Well you know, that is a crazy experience because the religion is so strict, it is very different. I went through a lot of phases and studied many religions... I am spiritual and have whatever relationship with God, you do not need the middlemen."
