Bob, there is an Adventism mindset of it being the final stop, therefore the only one, for modeling life. You have described what I concluded many years ago that there are countless ways to conduct life, all legitimate, outside of this one version.  

Adventism promotes the myth that it is the holder of the final solution for personal and universal history. When I was a pastor I watched parents in tears because their child had adopted a different life. Their last resort was to pray them back into the "Truth" so they would see them in heaven.

I have no animas toward Adventism. My choice to opt out was not out of anger, or a result of "backsliding," but a conscious intellectual judgment. Hell doesn't await anyone (or their children) who follow their, mind, heart and conscience.
