In everything I have ever read about complementarianism, the majority of these questions remain things I have never read answers for. With apologies to John Piper, I say:
The question complementarians have never satisfactorily answered for me is … what does it mean to … be a woman and not a man? … what does it mean to … be a man and not a woman? It will not do to just talk in terms of plumbing – biological – cause that’s not Biblical Manhood and Womanhood. And it won’t do to simply say accepting leadership, or leading – many women led and many men accepted leadership. Cause … I mean a woman and not a man.
