An influential Canadian doctors’ association has proposed expanding the country’s euthanasia laws so newborn babies suffering from serious disabilities could be given lethal drugs for the first time. In light of this, we discuss the often conflicting philosophies that lie behind our medical thinking on the unborn child versus newborn babies. What was so shocking and distinctive about how the early church treated babies so casually discarded by pagan Greco-Roman society? Are we losing this legacy of Christendom as both abortion and euthanasia are pushed ever further forward? What will it look like in the coming decades for Christians to bear witness to their counter-cultural convictions about the full humanity and dignity of babies?
