Among all the crimes which can be committed against life, procured abortion has characteristics making it particularly serious and deplorable. The Second Vatican Council defines abortion, together with infanticide, as an “unspeakable crime”.
But today, in many people’s consciences, the perception of its gravity has become progressively obscured. The acceptance of abortion in the popular mind, in behaviour and even in law itself, is a telling sign of an extremely dangerous crisis of the moral sense, which is becoming more and more incapable of distinguishing between good and evil, even when the fundamental right to life is at stake. Given such a grave situation, we need now more than ever to have the courage to look the truth in the eye and to call things by their proper name, without yielding to convenient compromises or to the temptation of self-deception. In this regard the reproach of the Prophet is extremely straightforward: “Woe to those who call evil good and good evil, who put darkness for light and light for darkness” (Is 5:20). Especially in the case of abortion there is a widespread use of ambiguous terminology, such as “interruption of pregnancy”, which tends to hide abortion’s true nature and to attenuate its seriousness in public opinion. Perhaps this linguistic phenomenon is itself a symptom of an uneasiness of conscience. But no word has the power to change the reality of things: procured abortion is the deliberate and direct killing, by whatever means it is carried out, of a human being in the initial phase of his or her existence, extending from conception to birth.
The moral gravity of procured abortion is apparent in all its truth if we recognize that we are dealing with murder and, in particular, when we consider the specific elements involved. The one eliminated is a human being at the very beginning of life. No one more absolutely innocent could be imagined. In no way could this human being ever be considered an aggressor, much less an unjust aggressor! He or she is weak, defenceless, even to the point of lacking that minimal form of defence consisting in the poignant power of a newborn baby’s cries and tears. The unborn child is totally entrusted to the protection and care of the woman carrying him or her in the womb. And yet sometimes it is precisely the mother herself who makes the decision and asks for the child to be eliminated, and who then goes about having it done.
It is true that the decision to have an abortion is often tragic and painful for the mother, insofar as the decision to rid herself of the fruit of conception is not made for purely selfish reasons or out of convenience, but out of a desire to protect certain important values such as her own health or a decent standard of living for the other members of the family. Sometimes it is feared that the child to be born would live in such conditions that it would be better if the birth did not take place. Nevertheless, these reasons and others like them, however serious and tragic, can never justify the deliberate killing of an innocent human being. — from Evangelium Vitae (1995)
