What would you do?

Human life has intrinsic value.

Of course not... and this is a perfect example of why engaging in one ethically-questionable practice can lead to all sorts of unforeseen outcomes.

i challenge the premise that the fetus "wasn't yours." "your" child is whatever child that needs you and was put into your care, however it got to be there (though I think the case of the trauma from rape is more complicated). the need of the weak that determines our obligations, especially to the weak that we have the ability to care for.

i agree with Karl Barth (and amy laura hall, who pointed me to the passage) that there is no need to go to extraordinary lengths to have children that share one's genetic makeup, because the child that we've waited for has come. children should received as an opportunity to participate in a gift that God is giving to God for the divine delight and the common good, and all children should be received this way without discrimination, whether or not they are one's own. this is why all Christians, married or single, are required to adopt, which is the most Christian way of having children. in adoption, christians imitate and participate in the way that God relates to us in grace, a way made known to us in the Incarnate One. the more that children are commodified (a process in which in vitro fertilization participates, perhaps intrinsically, especially with the condemnable way that an excess of embryos are made and then frozen), the more it makes sense to kill a baby that one voluntarily had put in one's womb because the doctor made a mistake. people should realize that this type of mistake is just one of the risks inherent in the practice of in vitro fertilization. killing the child just speaks to the narcissism and acquisitive greed of those involved.
