1. If I am married my husband has spiritual authority over me.
Does that mean he is answerable to God for you? Remember...having authority GIVEN over others means the one to whom authority is delegated still answers to the one who gave it.
1 Cor. 7:4 The wife does not have authority over her own body, but the husband does;
1 Cor. 7:4 For the unbelieving husband is sanctified through his wife, and the unbelieving wife is sanctified through her believing husband; for otherwise your children are unclean, but now they are holy. 15 Yet if the unbelieving one leaves, let him leave; the brother or the sister is not under bondage in such cases, but God has called us to peace. 16 For how do you know, O wife, whether you will save your husband? Or how do you know, O husband, whether you will save your wife?
1 Cor. 11:3 But I would have you know, that the head of every man is Christ; and
the head of the woman is the man; and the head of Christ is God.
Eph. 5:22 Wives, submit yourselves unto your own husbands, as unto the Lord.
23 For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body.
24 Therefore as the church is subject unto Christ, so let the wives be to their own husbands
in every thing.
25 Husbands, love your wives, even as Christ also loved the church, and gave himself for it;
26 That he might sanctify and cleanse it with the washing of water by the word,
27 That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.
28 So ought men to love their wives as their own bodies. He that loveth his wife loveth himself.
29 For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church:
30 For we are members of his body, of his flesh, and of his bones.
So, yes, I believe every Christian husband will answer for his treatment of his wife. His leadership is to help her to be holy and without blemish.
