No, submission does not extend to having the same worldview/ belief as your husband.
Directions for wife of non-believing husband verses 1-2, more generalised verses 3-6.
1 Peter 3:1-6
Immediately after the verse for husband, if followed would make him a wonderful man indeed.
7
Likewise, ye husbands, dwell with them according to knowledge, giving honour unto the wife, as unto the weaker vessel, and as being heirs together of the grace of life; that your prayers be not hindered.
Eve was to be Adam's helper, not servant or slave. It is sinful mankind that has created the dysfunction and chaos between husband and wife/ battle of the sexes.
1. It is very hard when he wants to do things that I cannot approve of. e.g. watch questionable movies.
I will not stop him from watching them, but I will not watch them. I have read several books specifically for Christian wives of unsaved husbands which advise submit to husband UNTIL that means breaking God's commandments. God is to be obeyed first.
2. Illiteracy was incredibly common for both men and women until fairly recently, it wasn't just women. That would be a factor in the extreme subjection of women in allegedly Christian churches and homes throughout history.
3. Women weren't able to go to church - where did you get that idea? In the Roman Catholic church and most churches until recently church leader roles were only for men, but were women ever prevented from attending Roman Catholic church/ other churches? If yes, I certainly never heard about that!!!
4. The bible states ALL people are sinners.
Romans 3:10
As it is written, There is none righteous, no, not one:
11 There is none that understandeth, there is none that seeketh after God.
12 They are all gone out of the way, they are together become unprofitable; there is none that doeth good, no, not one.
It is an individual's own faith or disbelief in Jesus which means if their eternal destination is Heaven or Hell. Neither man or woman can blame each other for that decision.
5. The divorce position is strongly debated amongst Christians. I come from a very imperfect family, I have the opinion there are some sins equally bad as adultery. e.g. p***philia (yes, I knew a sexually abused woman whose mother stayed with her husband because abuse of their daughter wasn't technically adultery) and domestic violence (I saw some of that while growing up).
Unfortunately not enough was said about this difficult topic in the bible to make boundaries extremely clear. I think it is very easy to say "NEVER EVER" until you live through it yourself.
When does domestic abuse become "bad enough" to permanently separate/ divorce for?
In the Age of the Internet, when does adultery become adultery?
Men and women are both to submit to God.
Women are to submit to their husband (only - we aren't told to obey every single man on earth).
Men are to take leadership role in the church according to bible commandments.
Your last sentence sounds like you believe the Catholic and the Christian viewpoint is the same thing. On this issue the Catholic church departs from the bible. Jesus is the ONLY mediator between men and God, no other person stands in between.
1 Timothy 2:5
For there is one God, and one mediator between God and men, the man Christ Jesus;
Men referring to mankind, therefore to women as well.
