So perhaps we would all be on the same page that husbands likewise have limited authority. After all I doubt any of us would suggest we can execute a wife for breaking some rule, right?
Hence the question becomes what the husband's authority entails and whether the wife has the legitimacy to judge her husband's authority based off solely her own ideals.
My concern, that I don't feel like anyone has really done a good job of addressing in discussing the 'wife is not required to follow an unrighteous leading' angle, is, as has been said: how does anyone make such a line? Or list/criteria, if you will.
My first wife, from the day I brought up poly, agreed it may be Biblically permitted but was adamant she did not want it. As it became more of a reality, other aspects were mentioned: it hurts emotionally, so I am unloving. Love is patient and kind but I am not just waiting on her pleasure, so I do not love her. She has not heard from God specifically that this is for us, so I must be making it up. Etc etc. In any of those things, she has judged me an "unrighteous leader' and thus, are we all suggesting she is justified in rebelling against me and leaving me?! I don't think so, but that is the trouble with approaching it from the righteous/unrighteous angle. Im going to echo what others have said: speaking to believers (I grant that Paul's word about a believing wife who has been divorced being free to remarry seems like the same rule does not apply to nonbelievers), Paul says for wives to submit to their husband as unto the Lord. I don't know how much more clear that could be...
