Pope Saint John Paul II on abortion as a type of murder:
“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.” [EV 58]
and on abortifacients as a type of abortion and a type of murder:
Pope Saint John Paul II: “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”.” [EV 61]
Pope Saint John Paul II: “The close connection which exists, in mentality, between the practice of contraception and that of abortion is becoming increasingly obvious. It is being demonstrated in an alarming way by the development of chemical products, intrauterine devices and vaccines which, distributed with the same ease as contraceptives, really act as abortifacients in the very early stages of the development of the life of the new human being.” [EV 13]
and on negative precepts and intrinsic evil:
Pope Saint John Paul II: “The negative moral precepts, those prohibiting certain concrete actions or kinds of behavior as intrinsically evil, do not allow for any legitimate exception. They do not leave room, in any morally acceptable way, for the creativity of any contrary determination whatsoever. Once the moral species of an action prohibited by a universal rule is concretely recognized, the only morally good act is that of obeying the moral law and of refraining from the action which it forbids.” [Veritatis Splendor 67].
