But what is technically possible is not for that very reason morally admissible
I have a problem with this. I am totally against abortion, but whenever the Vatican says things like this I can’t help but recall the previous Pope’s artificial hip and heart valve. Just why are medical advances that help a Pope OK but not medical advances to avoid pregnancies altogether, or help infertile couple have children? This seems to incongruous to me.
You're comparing apples with oranges. A heart valve or hip replacement has nothing to do with progeneration of life. Now take a close look at the post immediately following yours on this thread. This is a good example of what the Magisterium is referring to by the dangers of new technology that allows procreation apart from sexual relations.
I have a friend who implanted 4 embryos and 3 took. Her husband demanded that they go with "reduction." She held her ground and refused. She is now the proud mother of two boys and one girl --- all perfect and beautiful children. I often look at them and then scowl at her husband wondering which beautiful child would not be here if he had won.Now they fight over the disposition of the 2 remaining frozen embryos.
As for infertility, I've been there. The world is filled with parentless children and childless couples. Adoption is another way of forming a family. What difference does it make how a child comes into one's life? All children are gifts from God.
And, lastly, if you are not yet familiar with it, I would recommend you look into JPII's Theology of the Body
The 'Theology of the Body' is Pope John Paul II's integrated vision of the human person - body, soul, and spirit. As he explains, the physical human body has a specific meaning and is capable of revealing answers regarding fundamental questions about us and our lives:
The Church isn’t against ivf because it is artificial.
It is against ivf because it separates the unitive from the procreative - much like it is against artificial contraception because it separates the procreative from the unitive.
I think an accurate paraphrasing (in context) of this statement would be
“Just because something is technically possible doesn’t mean it is morally admissible”
