Oh, so a bit analogous to the ordination of Florence Li Tim-Oi; an ordination of a woman when there were no men available for the ministry?
It worked out okay for us, but I'm guessing Rome's not going to cope so well... has she been required to resign her orders? Or would they see that as validating them in the first place?
This is what a lot of people don't understand about the Catholic belief about ordination. Saying that there aren't any men so at a pinch a woman will step in and do it, kind of implies that this is something women can do, but we just don't let them do it because we think men are better or some such. This is not the case at all. From the Catholic point of view, this is like saying "well, there aren't any men around to be a father figure to you, so your mother will just be your father figure..." It doesn't work that way.
First, we believe that the sacrament of Holy Orders bestows a permanent mark upon the soul of the recipient. There is a real supernatural event that takes place which the Church has no power to change or alter in any way. It's not just the Church's way of saying.. "ok you're hired for this job and now we'll let you run this ministry".
Further, because sacraments carry very important and in most cases permanent, non-repeatable, effects, God has established conditions that define whether the sacrament actually occurred or not.
Sacraments have two basic components, form and matter. In order for a sacrament to be valid, it must have both valid form and valid matter. For example, with baptism the valid matter is you must have a living human being, and you must have water. The valid form is you must pour the water on the person (or dunk them in it) and say "I baptize you in the Name of the Father and the Son and the Holy Spirit" or some close variation of that, and you must have the intent to baptize them, and they must not be opposed to being baptized. If all those things are in place, you have valid form and valid matter. Therefore the sacrament is valid and it worked.
The required matter for Holy Orders is a baptized confirmed Catholic man.
It's not a matter of the Church simply refusing to ordain women, it is a matter that a woman cannot receive the sacrament of Holy Orders. It's impossible. Even if the ordination ritual is performed, it does nothing. It's not a matter of the Church approving it or disapproving it. The Church has no power to change this.
It would be like trying to baptize a cat, or to marry a car. Performing the ceremony or ritual is meaningless because the sacrament cannot be bestowed upon that kind of matter.
