To Teach the Law

Today, forty years after his death in 1978 (I was *just* born within his papacy), Blessed Pope Paul VI is canonised by Pope Francis in the Vatican. Paul VI appointed Popes John Paul I, John Paul II, and Benedict XVI to the College of Cardinals.

‘Our words would not be an adequate expression of the thought and solicitude of the Church, Mother and Teacher of all peoples, if, after having recalled men to the observance and respect of the divine law regarding matrimony, they did not also support mankind in the honest regulation of birth amid the difficult conditions which today afflict families and peoples. The Church, in fact, cannot act differently toward men than did the Redeemer. She knows their weaknesses, she has compassion on the multitude, she welcomes sinners. But at the same time she cannot do otherwise than teach the law. For it is in fact the law of human life restored to its native truth and guided by the Spirit of God.
 
The teaching of the Church regarding the proper regulation of birth is a promulgation of the law of God Himself. And yet there is no doubt that to many it will appear not merely difficult but even impossible to observe. Now it is true that like all good things which are outstanding for their nobility and for the benefits which they confer on men, so this law demands from individual men and women, from families and from human society, a resolute purpose and great endurance. Indeed it cannot be observed unless God comes to their help with the grace by which the goodwill of men is sustained and strengthened. But to those who consider this matter diligently it will indeed be evident that this endurance enhances man's dignity and confers benefits on human society.
 
The right and lawful ordering of birth demands, first of all, that spouses fully recognise and value the true blessings of family life and that they acquire complete mastery over themselves and their emotions. For if with the aid of reason and of free will they are to control their natural drives, there can be no doubt at all of the need for self-denial. Only then will the expression of love, essential to married life, conform to right order. This is especially clear in the practice of periodic continence. Self-discipline of this kind is a shining witness to the chastity of husband and wife and, far from being a hindrance to their love of one another, transforms it by giving it a more truly human character. And if this self-discipline does demand that they persevere in their purpose and efforts, it has at the same time the salutary effect of enabling husband and wife to develop to their personalities and to be enriched with spiritual blessings. For it brings to family life abundant fruits of tranquility and peace. It helps in solving difficulties of other kinds. It fosters in husband and wife thoughtfulness and loving consideration for one another. It helps them to repel inordinate self-love, which is the opposite of charity. It arouses in them a consciousness of their responsibilities. And finally, it confers upon parents a deeper and more effective influence in the education of their children. As their children grow up, they develop a right sense of values and achieve a serene and harmonious use of their mental and physical powers’.
