In 1995 Pope John Paul II declared that the Church’s teaching on abortion “is unchanged and unchangeable. Therefore, by the authority which Christ conferred upon Peter and his successors . . . 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 an innocent 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. No circumstance, no purpose, no law whatsoever can ever make licit an act which is intrinsically illicit, since it is contrary to the law of God which is written in every human heart, knowable by reason itself, and proclaimed by the Church” (Evangelium Vitae 62).
The early Church Fathers agreed. Fortunately, abortion, like all sins, is forgivable; and forgiveness is as close as the nearest confessional.
“The second commandment of the teaching: You shall not murder. You shall not commit adultery. You shall not seduce boys. You shall not commit fornication. You shall not steal. You shall not practice magic. You shall not use potions. You shall not procure [an] abortion, nor destroy a newborn child” (Didache 2:1–2 [A.D. 70]).
The Didache One of the most important sources from the age of the Apostolic Fathers is “The Lord’s Teaching through the Twelve Apostles to the Nations,” commonly referred to by its short name, the Didache (Greek for “teaching”).
