The point not addressed is how that role changed after Adam sinned. She now had an unrighteous head/leader.
I think that is tricky if we don't think of it as Adam representing God/Christ and the woman representing the
redeemed bride.
If we do, then I think we can take this reference:
Eze 1:26 And above the firmament that was over their heads was the
likeness of a throne, as the appearance of a sapphire stone: and upon the
likeness of the throne was the
likeness as the appearance of a man above upon it.
(First use of that same word:
Gen 1:26 And God said, Let us make
man in our image, after
our likeness: and let
them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth.
Gen 1:27 So God created
man in his own image, in the image of God created he
him;
male and female created he them. )
Back in Ezekiel who do we think might be worthy to sit on the throne? Adam? I don't think so, I don't think Adam (any other man) merits being on the throne Ezekiel saw. Only Christ deserves that.
The redeemed bride comprises brothers and sisters, not just sisters. So if the sister represents the redeemed bride, the sister represents brethren as well, both are in submission to the bridegroom.
The sisters keep silence in the presence of the brethren, but of course, when brethren are absent, sisters do from necessity many of the things (with their children for instance) that brethren would do if they were present.
When Christ is absent, brethren are charged with doing all sorts of things that Christ would do if he were present. So when he is back, brethren will keep silence as well in his presence.
Hab 2:20 But the LORD is in his holy temple: let all the earth keep silence before him.
At the moment, brethren are privileged to represent Christ in his absence.
Sisters actually represent the redeemed bride and that's a privilege as well, to represent the ones that will be judged worthy. And so sisters represent the brethren as well, for all must be subordinate to Christ.
I don't think any of that did change, because although Adam and Eve changed, God stayed above, and the relationship of angels and humans stayed beneath. It's just that things got moved around a bit down here.
The process of ageing was introduced (dying thou shalt die), and men and women were both cursed in that universal human aspiration of family: the man was cursed in his role of provider, and the woman in bearing children.
So in the present roles that God has decreed for brethren and sisters, they should both combine in one harmonious unity to represent the future glory when the family that God intends to make up will be revealed in the fulness of time.
