So much is made of this "natural resemblance" of  the "confector" but its validity is totally contradicted by the belief that He of whom the natural resemblance is required bears absolutely no resemblance in the species of His presence in bread and wine.  Q.E.D. and "duh?".  Applying it to the priest is dissimulation. And we have bought it.
Secondly, the required "maleness" of priest as representing Christ - the groom - is simultaneousely the feminine "Bride" of the church.The marital consummation "more than metaphor" as sexual- as declared by Ratzinger/Benedict is "intrinsicly" contrary to the Church notion of "natural law"  - not to mention physically impossible, as far as I can figure. The Bride is the Groom and the Groom is the Bride in some sort of -more than metaphorical - sexual event. And "we" along with our children are witnesses-participants?
