I understand that you want to remain neutral about "God stuff". I just wonder if you haven't done what you cautioned him against, ie: taking something away with nothing to replace it with. "I also explained, "When you open people's eyes up to the betrayal of trust you HARM THEM by taking away their safety net and destroy their WORLD! You inflict a wound! What are you prepared to REPLACE that with? Are you going to tell them to go to a Baptist Church, or become an atheist? You see, they have to SEE THE NEED TO GET OUT as survival of sanity. That's the only way which works."...
When you overheard the initial conversation and made the decision to step in it wasn't a question of his survival of sanity...
judging from what you've written so far I think that perhaps you and he don't share the same perception of the dynamics of your "relationship"...I hope that everything turns out all right and he isn't brought to psychological harm by what can only become an increasing void once his trust of others, familial relationships and friends are seen as "conditional"...
All I'm saying is this: It wouldn't hurt to be reminded that he has faith in someone and he can maintain that connection in a tangible way (when other thoughts and circumstances are chaotic) by reading his bible. you did it yourself in prison...it may be his only safety net.
