Also... If you come home early one day and catch your wife having sex with another woman or the family pet, that is NOT Spiritual Grounds for Divorce either...
Watchtower October 1, 1956 Page 591 paragraph 20:
Sodomy (or the unnatural intercourse of one male with another male as with a female), Lesbianism (or the homosexual relations between women), and bestiality (or the unnatural sexual relations by man or woman with an animal) are not Scriptural grounds for divorce. They are filthy, they are unclean, and God’s law to Israel condemned to death those committing such misdeeds, thus drastically putting these out of God’s congregation. But such acts are not adultery with the opposite sex, making the unclean person one flesh with another of the opposite sex. (Rom. 1:26-32) Yet there is a penalty of disfellowshiping attached to them.
