The Gospel’s stance on gender is to establish a common sharing of origins and derivative characteristics in relationship to the Father, through the Son, by the Spirit. Christ calls all to be reestablished into the family of God by accepting their place in the kingdom of God: a kingdom big enough for all! But, there is no general ontological role for either gender in this call. Gender is the wrong lens by which to define this call and is frankly too broad and ambiguous a lens to make work given the specificity of this call on people.
Read Romans 11:36-14:19 as one unit to get the next point…
An example of the approach above, that is, to understanding gender accurately in general biblical/theolgical terms here is to ask both Complimentarians and Egalitarians, have either of you ever read Proverbs 31:10-31? A better approach for understanding these types of texts, where a representative of a gender is living an idealized life, is not to force the vision of an idealized life into either of those models (Complimentarianism or Egalitarianism) but to see that kinship and glorification of the ideal individual are key to making an ideal “kingdom” if you will. There’s not a reducible model in the ideal for genders because an ideal society and individual flourish as they simultaneously flourish in their relationship to God.
Christ, in inaugurating the Kingdom of God, makes a space for the kinship of humanity to be reestablished with its only true God. But the ideal for genders in the fullest consummation and ideal state of the Kingdom is a genuine flourishing of both genders on their own terms because God has become a part of those terms (“or rather have become known by God”). This is why it’s so hard to understand the Bible’s view on gender, because these things are left in the tension of the occasions the books of the Bible were written in rather than spelled out theories in some weird modern model or categories like we like to have.
So, the truth is both models (Complimentarianism and Egalitarianism) fall short of the underriding logic of the Gospel and kingdom of God messages, and miss the nuance of the Jewish ideals being expressed in the relevant texts of the Bible.
