I would not think that God would place only married women under authority of men, while unmarried young women would be foot-loose and fancy-free. :?
It seems to me, that God's placing a curse on the ground, and requiring sweat from the brow in self-support, is passed on all mankind, women included.
And the words to Eve, were addressed to a married woman, but in fact, they affect all women, no matter what their station or situation. God has placed man in authority over women. Women are not to lead men.
The verse that says there is no male nor female in Christ is not saying men and women can ignore other commandments in the Bible concerning our God-given roles in the church or the home. Rather, the context is speaking of acceptance into the plan of salvation, just as God made an equal entrance into His family for all races, so did He make it equally easy for men and women, to become His children.
We are born again in our spirits, which are neither male nor female. But on this earth, we have to function as either one or the other. Therefore, we must submit to God's rules for functioning as male and female (in relationships toward each other), until we are freed from these mortal bodies.
God ordained that women be under the leadership and protection of men. Fathers and Husbands are to fulfill this role. My own husband does not. He left me. Therefore, since I am middle-aged, single, and my father is dead, I submit myself to my church leadership, as though they were my earthly male head. I have found this to be a great protection and comfort. It has given stability to my life, and has supplied the missing element of having a man to help me make decisions.
I feel America has left the foundation of the home, by choosing to reject God's Word concerning the role of women. Women in America have pushed and shoved men out of their role, usurping authority God never intended them to have. And they in turn have lost the respect, the protection and the freedom of the homemaker's role which God truely designed us for. Think about it. It is to women that God entrusted the training of the next generation. And what does America do now with babies?
The church of America has swallowed the lie of the women's rights movement. I for one, do not want to be counted among those on the broad road. The narrow path is not easy on the "old man" (or "old woman", in this case!

!), but it is the only way to heaven.
