Ven, could you please post the line(s) in the "bible" that makes everything confusing for your girlfriend? Maybe we can dissect the lines and find the "solution" we need.
One thing more, does her parents know of your "non-religious affiliation" already? I asked 'cause it kinda give relevance to the "style" you should present your arguments to her (tells also how "open" they are to each other).
