So, an Argentinian priest and bishop have now forced the entire Catholic Church to recognize the validity of the sacrament of marriage between transsexuals. It was a neatly done trick. Pope Francis would be very proud.
This is how it was done. A biological man and biological woman, each of whom presents as the other sex (man wears a dress, woman takes testosterone and tries to grow a beard), presented themselves to a friendly parish priest and asks to be married. Now, keep in mind, the couple fulfill canonical norms: marriage is between one man and one woman, that's what we have here, it's just that both are mentally unstable. But the Church has already approved the idea that such mentally unstable people can both be baptized into the Church and act as godparents for baptism or witnesses for marriage.
So, the priest, being no man's fool, talks with his bishop, to make sure bishop was ok with it. Bishop, being no man's fool, said, "Do it, but if it comes out, you will take the fall. We will put nothing in writing, which will keep Rome off my back." Priest said, "Sounds like a plan. Deal me in."
Now that the mockery is public, bishop announces an "investigation" and insists "there is nothing in writing that shows I approved of this." Bishop now will slow-walk the "investigation" until people stop watching, then drop it.
Notice that at no point is anyone talking about annulling the marriage. It cannot be annulled. There are no grounds because the marriage DID fulfill canonical norms (biological woman, biological man), and the Church presumption is always that a sacramental marriage is valid, so that has to be the presumption here.
Is the couple "open to life"? Sure. It is a biological male and a biological female, so conception could happen and the "man" could get pregnant. Heck, they may even WANT to do that so they have children to abuse. Unless either spouse contests the bond, the Church isn't going to contest - it can't. The default canonical position is ALWAYS "the bond is valid." That's canon law.
You might also say, "Well, the Church cannot marry the impotent." Sure, but sexual intercourse is not necessary for a valid marriage. As long as the sexual act could be completed in principle, that's enough. The two can be sterile - that doesn't matter. The Church has never defined what constitutes a vagina or a penis, and surgical reconstruction or "improvement" to allow for the act is certainly permissible, even encouraged, for heterosexual couples.
"It follows that any sex-change intervention, as a rule, risks threatening the unique dignity the person has received from the moment of conception. This is not to exclude the possibility that a person with genital abnormalities that are already evident at birth or that develop later may choose to receive the assistance of healthcare professionals to resolve these abnormalities." ~Dignitas Infinita, #60
The problem, of course, is what counts as "genital abnormalities." If people insist they were "born in the wrong bodies" then the presence or absence of a Y chromosome would create, in their bodies, what those very same people would insist is a "genital abnormality." The presence/absence of the offending chromosome would be a "genetic disease." Therefore, what counts as "assistance of healthcare professionals to resolve these abnormalities" is now up for grabs in a way that was never true prior to roughly this decade. No Church document addresses this. A sterile "penis" created from the muscle tissue of the forearm combined with a fake, surgically-constructed "vagina", a permanent wound that requires constant daily dilation ... well, the doctors are using the correct words, so what is the Church going to do? Say a medical doctor is wrong: that isn't a penis, that isn't a real vagina? Not likely.
As for the sexual act itself, that is not at all necessary for validity. This lack of consummation is the basis for a Josephite marriage, which - by definition - does not ever get consummated. Remember, Josephite marriages, because the participants remain virgins, are actually superior to marriages that are consummated.
The Result: As a Catholic you are REQUIRED to believe the marriage bond, in this instance, is valid until an annulment is declared, which it never will be. By this action, the entire Catholic Church is now bound to accept transsexual marriage. If you do not accept this marriage as valid, you are putting yourself outside the millennial-old teaching and practice of the Christ-founded Catholic Church.
If you're Catholic, you are now OK with transsexual marriage.
You're welcome.
