Hi,
Actually they are not suppose to beat their wives. I am not saying that this is legal in the faith of JW's. My sister was beaten about 3 times by her elder husband. She called elder meetings about this and he was warned. He stopped beating her for a while, but he does it again.
Although they knew it - he is still an elder. There is a shortage of elders in the congregation they are in. it is one of the "russian" congregations here in US. My sister is such a devout witness herself that many times she is just quiet about it. She just wants no trouble, she wants him to stay in the "elder" position so she just takes the abuse.
This is typical of witness women. Another friend of mine is living in "hell" with her witness husband who is an elder. He wont allow her to wear jeans, or pants. She cant wear any make up. Again - this is not typical of witnesses, but here is one example how far the "headship" doctrine can go. Every man interprets it differrently.
There are some that understand it only in a "spiritual" way. Like women can not pray aloud, or they cant lead the bible meeting etc... But some men just do whatever they want to with this doctrine.
The main point is that "headship" and "submission" doctrine is not a healthy doctrine at all and there is danger for women who's husbands "exercise" their "authority" in the family. Witness males are encouraged to exercise headship in their households. Them being imperfect man - there is no telling how far they can go. Many sisters suffer a lot. Believe me. I am still "officially" a witness myself. I have a family in this religion and I know soon I will lose them all.
I will keep posting on my blog all issues about women in watchtower. I jut started the blog a few days ago. You will find there specific issues and biblical explanations soon. For example, when Paul was writing about man being a "head" of the woman in Ephesians, he used the Greek word "kephale". The greek word "kephale" has no meaning of authority whatsever! "Kephale" carries the meaning of "foundation" or "cornestone" , not "authority". So Paul was simply saying that man is "foundation" of a woman like Christ is foundation of his church. He was trying to say that woman originated from man- she was taken out of man, not that he is her "authority"! In fact authority has nothing to do with Ephesians chapter 5 at all. It is a message of unity and love, not authority. Therefore the "headship" doctrine as JW's teach it has no foundation in the bible at all. All Christians are to submit to one another. It is not only one way- woman to a man. It is both ways.
I will have this all posted there in a few days so you can read it. Again it is http://freetoservechrist.blogspot.com
