I strongly oppose abortion on the basis that it is the deliberate killing of an innocent human life. However, I have recently had the difficulty of not being sure whether an embryo or foetus, at least in the early stages, is really a person.
It is indisputable that an embryo is biologically human from conception (just as the sperm and the egg are both biologically human), but that does not necessarily mean that he or she is a human being or person, with the same rights as any other. I think that when people ask, “When does life begin?” it is a misnomer; genetically a fertilised egg is just as human as a human adult, but then the same could be said of a human cheek cell. They mean “When does an embryo become a person?”
How do you define a person or human being, and how do you show that an unborn infant is a person and therefore has the same right to life as everyone else?
