Yes, you read that correctly.
I wonder if this calls under Pope Paul VI's prophecies somewhere.
In any case, what is exactly wrong with this picture? Scientists have simply found a way for a woman who carries mitochondrial diseases to have a child who is biologically hers. We're only fixing a disease, right?
Egg donation: Directive 40:
Heterologous fertilization (that is, any technique used to achieve conception by the use of gametes coming from at least one donor other than the spouses) is prohibited because it is contrary to the covenant of marriage, the unity of the spouses, and the dignity proper to parents and the child.It's a form of infidelity to use someone other than your spouse to have kids. It degrades the other person by using their gametes as a tool. It's degrading to the child who does not have the opportunity to be raised by their biological parent.
Sometimes it seems as if we forget that children are human beings. They are not commodities. They are not the property of their parents. No one has the right to have a child at all costs. Children are human beings. They are gifts from God made in His image with incalculable dignity. We have the responsibility to raise them, shelter them, feed them, and keep them free from diseases. Yes, it is our moral imperative to keep our child healthy, but not to the expense of others.
