Oh, I'm so sorry for your health problems and that it's alienated you from the church. I hope you can head back some day, if you want to. I've been harmed by medicine too - not as bad as you, but nonetheless, it's a chronic condition I'd rather not have to live with. Fortunately, no one has suggested that it's a problem relating to church - it only bothers me. We're staying away at the moment, because we still haven't fully integrated after covid. My husband has lung damage and we don't want covid. Not sure if we'll ever get totally back to normal.
What you say about biology of belief is also really interesting. Thank you.
