I have a 3 part question that I would like to ask...
First is in the Bible it says that the husband should be the leader in the household.
Is this pertaing to just the household or to Church also?
Wives, submit yourselves unto your own husgands, as unto the Lord. 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. Therefore as the church is subject unto Christ, so let the wives be to their own husbands in every thing. Ephesians 5:22-24
Based on this passage, I would say it means he is the leader in everything. The only thing I would add is that Christ is ultimately head over everyone, so if he is telling his wife to do something sinful, she doesn't have to obey. In all other cases, she should.
LIKEWISE, ye wives, be in subjection to your own husgnads: that, if any obey not the word, they also may without the word be won by the conversation of the wives. 1 Peter 3:1,2
For after this manner in the old time the holy women also, who trusted in God, adorned themselves, being in subjection unto their own husbands. Even as Sara obeyed Abraham, calling him lord: whose daughters ye are, as long as ye do well, and are not afraid with any amazement. 1 Peter 3:5,6
Second is if both man and wife have 2 different views on a particular biblical view and there is
no common ground then what should be done in such a situation?
Unless the husband is telling his wife to sin, based on the scriptures I gave, she should do as her husband says. The church has no place in deciding issues in the home, unless it is a sin issue.
Last is if women are to be living in the example of man how does that make her an unique individual
with her own thoughts, views, and personality that God created?
And the LORD God said, It is not good that the man should be alone; I will make him an help meet for him. Genesis 2:16
The woman was created to be a help meet to her husband, not someone who is to be independent or in opposition to her husband. In the marriage, they are one flesh, and that goes way beyond sex.
