The Worldwide Church of God is very similar in outlook and doctrine to JW's. Have you ever heard of "The Plain Truth" magazine? Rumor had it at one time that the head of the WWCOG, Herbert Armstrong, was once affiliated with the JW's, but I don't know if it's true.
Herbert's son, Garner Ted Armstrong, used to have a TV program. I don't know whether he's still in the preaching business or not.
I had a former co-worker who was a member of the WWCOG. She didn't celebrate Christmas and had other weird habits and beliefs. I think I was influential in getting her to stop going to that church, too.
As to what you can be, you can be anything. The sky's the limit.
