Are Christ and women eternally subordinated?

In the fourth century a church council denounced the belief in eternal subordinationism of the Son to the Father within the Trinity, and called that belief a heresy. Eternal subordinationism claimed that the Son was unequal to the Father both in value (not as fully deity as the father is) and role. Today some teach that while eternal subordinationism is heretical, it is not heretical to believe that the Son is eternally subordinate to the Father. CBMW's Gender Blog begins a series today promoting the eternal subordination (not subordinationism) of the Son to the Father. From this starting point, our brothers and sisters at CBMW believe that God has designed a hierarchical pattern in the Trinity which is reflected elsewhere in relationships. In this hierarchy some individuals are equal in value but different in roles from other individuals. In this hierarchy wives are subordinate to husbands.

Three years ago Bible scholar Ben Witherington blogged that there is no eternal subordination for either Christ or women.

What do you think? And why?
