Glad to see you back. It sounds like you really have your hands full with a lot on your plate. There are lots of other people on here who probably have better information for you. I would almost suggest that you go talk to a professional (clergy, pdoc, therapist) about your husband and his most recent behavior. Those are some pretty strong comments he's making and its probably important to get a second, impartial opinion. I understand that religion can be an important part of a person's well being (physical, social, emotional, spiritual, etc) and most people here would never doubt the importance of religon in a person's life. But it shouldn't take the place of medication and proper care.
My thoughts are with you,
Overzealousnes in religion is a very common symptom of untreated mania. I went through it myself, and the very next day after coming down in the hospital, it went away and never came back. Amazing. Your husband is very ill, he really needs to be treated, I am sorry for what you are going through.
