What is the main idea of this passage?

It is very interesting that for Aristotle women were not considered slaves that had to obey blindly every desire of their husband but at the same time women were not considered superior or equal to men.

This explains why in the text that you are quoting women have very important responsibilities such as the care of everything at home, control over financial matters and many other issues that came under the approval of her husband. Women however; would not be involve in issues from outside her home. She would respect her husband and consider him a divine entity.  

Explanation:

At the end of the day, while the text might at first sound like his personal opinion (as  the philosopher that he was) about women, in reality he is helping them to find true happiness and an easy way to handle their responsibilities at home. If women follow these standards, the will earn the title "Good Wife".
