If memory serves, you mentioned "Tobias."  Then you said "Tobias was a typo, Tobit."  St John Paul II, in his analysis of Tobit, says that the language of the body, male and female, in *nuptial interaction,* is liturgical.  If so, how can this be irrelevant to the priesthood?  Could it be that there is a linkage between the sacrament of marriage and the sacrament of holy orders?

Humans are intrinsically personal subjects, body-souls.  Bodily sex does not constitute the integral totality of personal subjects as body-souls.  Are you familiar with the Theology of the Body?  I think it can be extended to all the sacraments, including holy orders.  Christ is both priest and victim, and offered himself in sacrifice as God who became a body-soul.  

For this reason, the priest must be a human body-soul, male or female or intersex.  Could it be that what is missing in our patriarchal theology of the priesthood is the need to make visible the divine "feminine genius" in Jesus?
