This is also in the Epistles and is the basis of old language in the wedding ceremony, "to obey. " It is better to think of it in terms of "cooperative. "
It means that the wife should always obey her husband and follow his lead in everything. Basically, it took a lot of freedom from Christian women for centuries as they lived in a male-dominated culture. It is still the way that a lot of people think today, although things are slowly changing.
Biblical submission is not like slavery. The Bible uses the analogy of Jesus's relationship to the church. As the church submits to Christ, so a wife to a husband.
In the Bible, when it says a wife must be submissive, it means that she must let her husband tell her what to do and do it with the utmost respect. Any sort of disrespect is basically a sin.
