Hi Apostlestate-
First off, Welcome to JWD. It's great to see 'lurkers' speak up.
I don't have much research guidance myself but there is so much info here. While waiting for others to post here, you might look back on some threads that 'Ithinkisee' started. He did quite a bit of research to help his believing wife see the truth about the 'truth'.
FYI - you posted at a time of day when many people are sleeping and your thread may get pushed back from the top of 'Active Topics'. If that happens, you can add a post to this thread to Bump it to the top (bttt).
Another tip may be to start another thread asking for assistance with the specific doctrinal aspect you cited. Many will jump on that especially if you get right to the point. Many here like to read the stories, others get distracted or are too busy but are more inclined to respond with quick reference notes.
Sorry I'm not more helpful but hopefully keeps your topic active enough to get more responses.
Take care and again: Welcome!
-Denise.
