Evangelium Vitae §61

⁶¹ The texts of Sacred Scripture never address the question of deliberate abortion and so do not directly and specifically condemn it. But they show such great respect for the human being in the mother's womb that they require as a logical consequence that God's commandment "You shall not kill" be extended to the unborn child as well. Human life is sacred and inviolable at every moment of existence, including the initial phase which precedes birth. All human beings, from their mothers' womb, belong to God who searches them and knows them, who forms them and knits them together with his own hands, who gazes on them when they are tiny shapeless embryos and already sees in them the adults of tomorrow whose days are numbered and whose vocation is even now written in the "book of life" (cf. Ps 139: 1, 13-16). There too, when they are still in their mothers' womb-as many passages of the Bible bear witness -they are the personal objects of God's loving and fatherly providence. Christian Tradition-as the Declaration issued by the Congregation for the Doctrine of the Faith points out so well -is clear and unanimous, from the beginning up to our own day, in describing abortion as a particularly grave moral disorder. From its first contacts with the Greco-Roman world, where abortion and infanticide were widely practised, the first Christian community, by its teaching and practice, radically opposed the customs rampant in that society, as is clearly shown by the Didache mentioned earlier. Among the Greek ecclesiastical writers, Athenagoras records that Christians consider as murderesses women who have recourse to abortifacient medicines, because children, even if they are still in their mother's womb, "are already under the protection of Divine Providence". Among the Latin authors, Tertullian affirms: "It is anticipated murder to prevent someone from being born; it makes little difference whether one kills a soul already born or puts it to death at birth. He who will one day be a man is a man already". Throughout Christianity's two thousand year history, this same doctrine has been constantly taught by the Fathers of the Church and by her Pastors and Doctors. Even scientific and philosophical discussions about the precise moment of the infusion of the spiritual soul have never given rise to any hesitation about the moral condemnation of abortion.
