The constitution of the Church is hierarchical (apostolic) but not necessarily patriarchal.  I choose to keep hoping for clarification, because it is a critical issue that must be resolved as the patriarchal phase of salvation history passes away.  The crisis of vocations is a symptom that the conflation of hierarchy and patriarchy is hurting the entire body of Christ.  Allowing nuns to be ordained would double the number of priests overnight.  Why not?  Prayers!
