The Church's teaching on IVF rescue is inscrutable. In Dignitas Personae #19, the Church tells us "All things considered, it needs to be recognized that the thousands of abandoned embryos represent a situation of injustice which in fact cannot be resolved."
Think about that.
With that statement, the Church tells us that women cannot adopt frozen embryos.
This means IVF is a sin of such magnitude, that a Catholic cannot even offer her own womb as sanctuary for a child who will otherwise starve and freeze to death, buried alive in a frozen nitrogen grave. Yes, this is the fate of every abandoned embryo. Such children cannot even be baptized, for the simple act of baptizing an embryonic frozen child would kill the child. So, since the Church forbids IVF rescue and cannot apply the sacraments, all those thousands of abandoned embryonic children cannot be adopted, they must instead die unshriven, placing their salvation into a state known only to God. (CCC 1261).
Whenever anyone tells you the Church cares more about embryos than it does about women, bring forward this counter. It is essentially the only time a woman can be uniquely damned to hell for having saved a child's life. Women are forbidden to save children conceived through IVF.
The Church looks upon the freezing, starving IVF children, throws up her hands and says, "Well, isn't that sad? Ladies, don't even think about rescuing those children. You are not permitted to take up that cross or lay down your life for them, not even your wombs. For these IVF children, you cannot even temporarily donate the use of your organs. We're fine with wet nursing, but we have to draw the line somewhere. You just stand back and watch them die, do you hear?"
Makes you proud to be a Catholic, don't it?
