I would imagine that there would be serious ontological problems were women to become priests.
I believe one of the biggest problems lies with the whole concept of Christ and His Church. Christ is the Bridegroom, and his Church is portrayed as being the Bride of Christ. As you know, the priest, in the mass and at the altar, represents Christ. Were a female to become a priest, the powerful image of Christ being the bridegroom being united with his Church would be significantly clouded. In other words, Scripture and the Tradition of the Church employ profound images that themselves make use of the sexuality between a man and a woman.
I hope that makes some sense to you. I myself don’t fully understand the argument; but I have come across it a number of times, and it seems a fairly good reason why women can never become priests.
I personally believe, for theological reasons, that women should not become priests. I have read, however, that some women in the early Christian times were deacons. I haven’t looked into it, however. In all, I would imagine that we will see female deacons than female priests in the near future.
