Today, a couple of selections from one of the watershed moments of his Papacy, the encyclical Humanae Vitae (July 25, 1968), where the crisis of dissent in the Catholic Church erupted, and whose effects are still with us.
Paragraph 17 is generally regarded as prophetic:
17. Responsible men can become more deeply convinced of the truth of the doctrine laid down by the Church on this issue if they reflect on the consequences of methods and plans for artificial birth control. Let them first consider how easily this course of action could open wide the way for marital infidelity and a general lowering of moral standards. Not much experience is needed to be fully aware of human weakness and to understand that human beings—and especially the young, who are so exposed to temptation—need incentives to keep the moral law, and it is an evil thing to make it easy for them to break that law. Another effect that gives cause for alarm is that a man who grows accustomed to the use of contraceptive methods may forget the reverence due to a woman, and, disregarding her physical and emotional equilibrium, reduce her to being a mere instrument for the satisfaction of his own desires, no longer considering her as his partner whom he should surround with care and affection.This principle is worth reflecting on today, as even newer challenges to the dignity of human life arise in our time:
Consequently, unless we are willing that the responsibility of procreating life should be left to the arbitrary decision of men, we must accept that there are certain limits, beyond which it is wrong to go, to the power of man over his own body and its natural functions—limits, let it be said, which no one, whether as a private individual or as a public authority, can lawfully exceed.
And this is truly prophetic, especially in light of what we have seen in the Church in the last two weeks
18. It is to be anticipated that perhaps not everyone will easily accept this particular teaching. There is too much clamorous outcry against the voice of the Church, and this is intensified by modern means of communication. But it comes as no surprise to the Church that she, no less than her divine Founder, is destined to be a "sign of contradiction." (22) She does not, because of this, evade the duty imposed on her of proclaiming humbly but firmly the entire moral law, both natural and evangelical.
Since the Church did not make either of these laws, she cannot be their arbiter—only their guardian and interpreter. It could never be right for her to declare lawful what is in fact unlawful, since that, by its very nature, is always opposed to the true good of man.
In preserving intact the whole moral law of marriage, the Church is convinced that she is contributing to the creation of a truly human civilization. She urges man not to betray his personal responsibilities by putting all his faith in technical expedients. In this way she defends the dignity of husband and wife. This course of action shows that the Church, loyal to the example and teaching of the divine Savior, is sincere and unselfish in her regard for men whom she strives to help even now during this earthly pilgrimage "to share God's life as sons of the living God, the Father of all men." (23)Read it all!
Beate Paule VI, ora pro nobis!
