John Paul II in confirming the Church’s condemnation of abortion in Evangelium vitae:

"Therefore, by the authority which Christ conferred on Peter and his Successors, in communion with the Bishops …. I declare that direct abortion, that is, abortion willed as an end or as a means, always constitutes a grave moral disorder, since it is the deliberate killing of a human being. This doctrine is based upon the natural law and upon the written Word of God, is transmitted by the Church’s Tradition and taught by the ordinary and universal Magisterium."
