Casti Connubii on Christian Marriage

Excerpt: How great is the dignity of chaste wedlock, Venerable Brethren, may be judged best from this that Christ Our Lord, Son of the Eternal Father, having assumed the nature of fallen man, not only, with His loving desire of compassing the redemption of our race, ordained it in an especial manner as the principle and foundation of domestic society and therefore of all human intercourse, but also raised it to the rank of a truly and great sacrament of the New Law, restored it to the original purity of its divine institution, and accordingly entrusted all its discipline and care to His spouse the Church. 2. In order, however, that amongst men of every nation and every age the desired fruits may be obtained from this renewal of matrimony, it is necessary, first of all, that men's minds be illuminated with the true doctrine of Christ regarding it; and secondly, that Christian spouses, the weakness of their wills strengthened by the internal grace of God, shape all their ways of thinking and of acting in conformity with that pure law of Christ so as to obtain true peace and happiness for themselves and for their families. 3. Yet not only do We, looking with paternal eye on the universal world from this Apostolic See as from a watch-tower, but you, also, Venerable Brethren, see, and seeing deeply grieve with Us that a great number of men, forgetful of that divine work of redemption, either entirely ignore or shamelessly deny the great sanctity of Christian wedlock, or relying on the false principles of a new and utterly perverse morality, too often trample it under foot. And since these most pernicious errors and depraved morals have begun to spread even amongst the faithful and are gradually gaining ground, in Our office as Christ's Vicar upon earth and Supreme Shepherd and Teacher We consider it Our duty to raise Our voice to keep the flock committed to Our care from poisoned pastures and, as far as in Us lies, to preserve it from harm. 4. We have decided therefore to speak to you, Venerable Brethren, and through you to the whole Church of Christ and indeed to the whole human race, on the nature and dignity of Christian marriage, on the advantages and benefits which accrue from it to the family and to human society itself, on the errors contrary to this most important point of the Gospel teaching, on the vices opposed to conjugal union, and lastly on the principal remedies to be applied. In so doing We follow the footsteps of Our predecessor, Leo XIII, of happy memory, whose Encyclical Arcanum, published fifty years ago, We hereby confirm and make Our own, and while We wish to expound more fully certain points called for by the circumstances of our times, nevertheless We declare that, far from being obsolete, it retains its full force at the present day. 5. And to begin with that same Encyclical, which is wholly concerned in vindicating the divine institution of matrimony, its sacramental dignity, and its perpetual stability, let it be repeated as an immutable and inviolable fundamental doctrine that matrimony was not instituted or restored by man but by God; not by man were the laws made to strengthen and confirm and elevate it but by God, the Author of nature, and by Christ Our Lord by Whom nature was redeemed, and hence these laws cannot be subject to any human decrees or to any contrary pact even of the spouses themselves. This is the doctrine of Holy Scripture; this is the constant tradition of the Universal Church; this the solemn definition of the sacred Council of Trent, which declares and establishes from the words of Holy Writ itself that God is the Author of the perpetual stability of the marriage bond, its unity and its firmness.
