2old, it does make sense you cannot reach out whatever their belief. My W was a Christian, believed quite seriously, even been singing at her church for the last 12 years. In my early days I even brought up (shouldn't have, I know now) what the bible says about divorce etc. She even has a tattoo on her lower back saying "Faith". I questioned how she could have this belief but then not follow through. All I got was, I am still a Christian and I know what the bible says, but that is that.
