Catechism of the Council of Trent: Holy Matrimony
The Motives And Ends Of Marriage
We have now to explain why man and woman should be joined in marriage. First of all, nature itself by an instinct implanted in both sexes impels them to such companionship, and this is further encouraged by the hope of mutual assistance in bearing more easily the discomforts of life and the infirmities of old age.
A second reason for marriage is the desire of family, not so much, however, with a view to leave after us heirs to inherit our property and fortune, as to bring up children in the true faith and in the service of God. That such was the principal object of the holy Patriarchs when they married is clear from Scripture. Hence the Angel, when informing Tobias of the means of repelling the violent assaults of the evil demon, says: I will show thee who they are over whom the devil can prevail; for they who in such manner receive matrimony as to shut out God from themselves and from their mind, and to give themselves to their lust, as the horse and mule which have not understanding, over them the devil hath power. He then adds: Thou shalt take the virgin with the fear of the Lord, moved rather for love of children than for lust, that in the seed of Abraham thou mayest obtain a blessing in children. It was also for this reason that God instituted marriage from the beginning; and therefore married persons who, to prevent conception or procure abortion, have recourse to medicine, are guilty of a most heinous crime—nothing less than wicked conspiracy to commit murder.
A third reason has been added, as a consequence of the fall of our first parents. On account of the loss of original innocence the passions began to rise in rebellion against right reason; and man, conscious of his own frailty and unwilling to fight the battles of the flesh, is supplied by marriage with an antidote by which to avoid sins of lust. For fear of fornication, says the Apostle, let every man have his own wife, and let every woman have her own husband; and a little after, having recommended to married persons a temporary abstinence from the marriage debt, to give themselves to prayer, he adds: Return together again, lest Satan tempt you for your incontinency.
These are ends, some one of which, those who desire to contract marriage piously and religiously, as becomes the children of the Saints, should propose to themselves. If to these we add other causes which induce to contract marriage, and, in choosing a wife, to prefer one person to another, such as the desire of leaving an heir, wealth, beauty, illustrious descent, congeniality of disposition—such motives, because not inconsistent with the holiness of marriage, are not to be condemned. We do not find that the Sacred Scriptures condemn the Patriarch Jacob for having chosen Rachel for her beauty, in preference to Lia.
So much should be explained regarding Matrimony as a natural contract.
Marriage Considered as a Sacrament
It will now be necessary to explain that Matrimony is far superior in its sacramental aspect and aims at an incomparably higher end. For as marriage, as a natural union, was instituted from the beginning to propagate the human race; so was the sacramental dignity subsequently conferred upon it in order that a people might be begotten and brought up for the service and worship of the true God and of Christ our Saviour.
Thus when Christ our Lord wished to give a sign of the intimate union that exists between Him and His Church and of His immense love for us, He chose especially the sacred union of man and wife. That this sign was a most appropriate one will readily appear from the fact that of all human relations there is none that binds so closely as the marriage-tie, and from the fact that husband and wife are bound to one another by the bonds of the greatest affection and love. Hence it is that Holy Writ so frequently represents to us the divine union of Christ and the Church under the figure of marriage.
Marriage Is A Sacrament
That Matrimony is a Sacrament the Church, following the authority of the Apostle, has always held to be certain and incontestable. In his Epistle to the Ephesians he writes: Men should love their wives as their own bodies. He that loveth his wife loveth himself. For no man ever hated his own flesh, but nourisheth it and cherisheth it, as also Christ doth the church; for we are members of his body, of his flesh, and of his bones. For this cause shall a man leave his father and mother, and shall adhere to his wife, and they shall be two in one flesh. This is a great sacrament; but I speak in Christ and in the church. Now his expression, this is a great sacrament, undoubtedly refers to Matrimony, and must be taken to mean that the union of man and wife, which has God for its Author, is a Sacrament, that is, a sacred sign of that most holy union that binds Christ our Lord to His Church.
That this is the true and proper meaning of the Apostle's words is shown by the ancient holy Fathers who have interpreted them, and by the explanation furnished by the Council of Trent. It is indubitable, therefore, that the Apostle compares the husband to Christ, and the wife to the Church; that the husband is head of the wife as Christ is the head of the Church; and that for this very reason the husband should love his wife and the wife love and respect her husband. For Christ loved his church, and gave himself for her; while as the same Apostle teaches, the church is subject to Christ.
That grace is also signified and conferred by this Sacrament, which are two properties that constitute the principal characteristics of each Sacrament, is declared by the Council as follows: By his passion Christ, the Author and Perfecter of the venerable Sacraments, merited for us the grace that perfects the natural love (of husband and wife), confirms their indissoluble union, and sanctifies them. It should, therefore, be shown that by the grace of this Sacrament husband and wife are joined in the bonds of mutual love, cherish affection one towards the other, avoid illicit attachments and passions, and so keep their marriage honourable in all things, . . . and their bed undefiled.
Marriage before Christ
It Was Not A Sacrament
How much the Sacrament of Matrimony is superior to the marriages made both previous to and under the (Mosaic) Law may be judged from the fact that though the Gentiles themselves were convinced there was something divine in marriage, and for that reason regarded promiscuous intercourse as contrary to the law of nature, while they also considered fornication, adultery and other kinds of impurity to be punishable offences; yet their marriages never had any sacramental value.
Among the Jews the laws of marriage were observed far more religiously, and it cannot be doubted that their unions were endowed with more holiness. As they had received from God the promise that in the seed of Abraham all nations should be blessed, it was justly considered by them to be a very pious duty to bring forth children, and thus contribute to the propagation of the chosen people from whom Christ the Lord and Saviour was to derive His birth in His human nature. Still their unions also fell short of the real nature of a Sacrament.
Before Christ Marriage Had Fallen From Its Primitive Unity And Indissolubility
It should be added that if we consider the law of nature after the fall and the Law of Moses we shall easily see that marriage had fallen from its original honour and purity. Thus under the law of nature we read of many of the ancient Patriarchs that they had several wives at the same time; while under the Law of Moses it was permissible, should cause exist, to repudiate one's wife by giving her a bill of divorce. Both these (concessions) have been suppressed by the law of the Gospel, and marriage has been restored to its original state.
Christ Restored to Marriage its Primitive Qualities
Unity Of Marriage
Though some of the ancient Patriarchs are not to be blamed for having married several wives, since they did not act thus without divine dispensation, yet Christ our Lord has clearly shown that polygamy is not in keeping with the nature of Matrimony. These are His words: For this cause shall a man leave father and mother, and shall cleave unto his wife, and they shall be two in one flesh; and He adds: wherefore they are no more two but one flesh. In these words He makes it clear that God instituted marriage to be the union of two, and only two persons. The same truth He has taught very distinctly in another passage, wherein He says: Whosoever shall put away his wife and marry another, committeth adultery against her; and if the wife shall put away her husband, and be married to another, she committeth adultery. For if it were lawful for a man to have several wives, there is no reason why he who takes to himself a second wife, along with the wife he already has, should be regarded as more guilty of adultery than if he had dismissed his first wife and taken a second.
Hence it is that when an infidel who, following the customs of his country has married several wives, happens to be converted to the true religion, the Church orders him to dismiss all but the first, and regard her alone as his true and lawful wife.
