If a person's right to life is violated at the moment in which he is first conceived in his mother's womb, an indirect blow is struck also at the whole of the moral order, which serves to ensure the inviolable goods of man. Among those goods, life occupies the first place. The Church defends the right to life, not only in regard to the majesty of the Creator, who is the First Giver of this life, but also in respect of the essential good of the human person.
--Pope John Paul II, 1979
