I highly doubt that Morris just quit for health reasons and there was not a sorrow full announcement about it. Brother Morris has become ill bla bla bla. He was pushed out or he would be at Wallkill today. He obviously has a drinking issue and is most likely an alcoholic.
That could be one reason. Another could be that Morris was one of the very hard liners. As we watch this cult start to try to be less dictatorial or at least appear that way as secular criticism ramps up, he may have pushed back on the way the cult has tried to soften its image. Could be a combination of the two. It has been surprisingly quiet about this. No scuttlebutt from any good sources. One thing is obvious, he was given a home and most likely a stipend to live on.
