I personally know many who suffer from mental issues and in the past have come into contact with many unsympathetic, judging elders. For instance my dad and his OCD. While he is not delusional or anything remotely like that, the elders used to avoid him. Now, to this day my father is extremely zealous and strong in his faith and I love that about him. But how much easier his life would've been with a bit of association from the congregation...but it never happened. And because of my dad's mental illness, us kids were avoided like the plague. You can imagine how lonely our growing years were .
In fact, only last year, some 20yrs after dad's illness was diagnosed, I overheard some 20 somethings talking about me and how 'you know her dad is nuts, so is she'. I mean, where did THAT come from?? Why did they feel they could judge me or my dad like that? My dad (and me) is nowhere near nuts. He keeps to himself, studies the bible everyday for hours, keeps his nose clean and is the meekest, mildest, well spoken man I have ever met.
Thankfully I think the organisation is starting to view mental illness in a better light and for the most part, just *some* elders still have the mentality that it's self brought on or demonic. Now my dad is in a different congregation, he receives many visitors and is loved by all. If only he had received that same care 20yrs ago!
