I wasn't offended by the word "gang", why would you be offended by the word "group"? Matter of fact I saw it as the same word. Just questioning the reason to not worship or live in the manner that we do.
Yes, there is a huge difference in whom we are speaking of as our Lord and spoken of in the bible. However, like Rainy, I pray that you become the christian that you were meant to be. I never give up hope in that.
