The need for a priest to have a "natural resemblance" to the male Jesus is just another rationalization of patriarchal gender ideology.  Going forward, I think we need to *make visible* the feminine genius in Jesus, and the masculine genius in Mary, that influenced their behavior in the flesh, their actions and their body language.  The "acting person" is what matters, not just the external appearance of the body.  The body is a sacrament of the entire person, but is not the entire person.  If this is true for humans, even more so for Christ, who is a divine person.
