Gary,
That is an interesting post about "absolute spiritual endangerment", which is one of the Watchtower's allowable reasons for marital separation.
This doctrine of "absolute spiritual endangerment" presents the dark side of the so-called "three-fold cord" that the JW's sing about. The third fold is not really Jehovah in practice, but rather the religious organization of JW's. They can dictate to you how to behave in marriage. The idea of "spiritual endangerment" allows the elders to make a ruling on whether a wife should continue to stay together with her husband. She probably cannot apply the "spiritual endangerment" rule without their consent.
Therefore, the elders can subtly exercise more influence on the woman than even the husband. I know, I've seen it, and it has made me absolutely sick!!!!
