Pardon me, yet I could read no further, upon seeing this:
plan to visit a meeting of Jehovah's Witnesses, to find out what it is all about and learn more about what my girlfriend has been brought up believing,
If I may...a meeting will not give you clear, transparent visuals for your search.
To truly LEARN, to study their beliefs and how those beliefs are designed to fit ONLY the organizations of the Watchtower Book Publishing CORPORATION {BUSINESS}, you would need to study further on how they form and structure policies. LETHAL policies. Policies no one has the birthright to form in the first place. Not to mention a man-made publishing organization masked as true, loving organization of god.
Please keep in mind this: when you are new and start just only going to meetings and not having a "bible study", they will be watching you all the time. Trust me, meetings are where they size you up. That and how much more time are you truly devoted to giving the WTOrg { aka Jehovah's Witnesses }
Also, it would be wise during your re-search that you invest as much time in discovering the Watchtower Bible Tract Society shadier side as you do in searching out their even shadier doctrines and policies.
Hope I'm not coming off too caustic here. I sincerely want lurkers and seekers to get heavier into their research and start questioning more.
It's good to see this type of post...householder starts going to meetings and asking questions about "religion" that hates anyone not a jw and if I stop meetings and studying, I'm dead meat. LOLOLOL!!!
Because face it, it's what they really think! Don't be fooled. Jw's have mastered The Mask.
