Though revilers of the Christian faith refuse to acknowledge the never-interrupted doctrine of the Church on this subject and have long striven to destroy the testimony of all nations and of all times, they have nevertheless failed not only to quench the powerful light of truth, but even to lessen it. We record what is to all known, and cannot be doubted by any, that God, on the sixth day of creation, having made man from the slime of the earth, and having breathed into his face the breath of life, gave him a companion, whom He miraculously took from the side of Adam when he was locked in sleep. God thus, in His most far-reaching foresight, decreed that this husband and wife should be the natural beginning of the human race, from whom it might be propagated and preserved by an unfailing fruitfulness throughout all futurity of time. And this union of man and woman, that it might answer more fittingly to the infinite wise counsels of God, even from the beginning manifested chiefly two most excellent properties – deeply sealed, as it were, and signed upon it-namely, unity and perpetuity. From the Gospel we see clearly that this doctrine was declared and openly confirmed by the divine authority of Jesus Christ. He bore witness to the Jews and to His Apostles that marriage, from its institution, should exist between two only, that is, between one man and one woman; that of two they are made, so to say, one flesh; and that the marriage bond is by the will of God so closely and strongly made fast that no man may dissolve it or render it asunder. “For this cause shall a man leave father and mother, and shall cleave to his wife, and they two shall be in one flesh. Therefore now they are not two, but one flesh. What, therefore, God bath joined together, let no man put asunder.”
This form of marriage, however, so excellent and so pre-eminent, began to be corrupted by degrees, and to disappear among the heathen; and became even among the Jewish race clouded in a measure and obscured. For in their midst a common custom was gradually introduced, by which it was accounted as lawful for a man to have more than one wife; and eventually when “by reason of the hardness of their heart,” Moses indulgently permitted them to put away their wives, the way was open to divorce.
But the corruption and change which fell on marriage among the Gentiles seem almost incredible, inasmuch as it was exposed in every land to floods of error and of the most shameful lusts. All nations seem, more or less, to have forgotten the true notion and origin of marriage; and thus everywhere laws were enacted with reference to marriage, prompted to all appearance by State reasons, but not such as nature required. Solemn rites, invented at will of the law-givers, brought about that women should, as might be, bear either the honorable name of wife or the disgraceful name of concubine; and things came to such a pitch that permission to marry, or the refusal of the permission, depended on the will of the heads of the State, whose laws were greatly against equity or even to the highest degree unjust. Moreover, plurality of wives and husbands, as well as divorce, caused the nuptial bond to be relaxed exceedingly. Hence, too, sprang up the greatest confusion as to the mutual rights and duties of husbands and wives, inasmuch as a man assumed right of dominion over his wife, ordering her to go about her business, often without any just cause; while he was himself at liberty “to run headlong with impunity into lust, unbridled and unrestrained, in houses of ill-fame and amongst his female slaves, as if the dignity of the persons sinned with, and not the will of the sinner, made the guilt.” When the licentiousness of a husband thus showed itself, nothing could be more piteous than the wife, sunk so low as to be all but reckoned as a means for the gratification of passion, or for the production of offspring. Without any feeling of shame, marriageable girls were bought and sold, tike so much merchandise, and power was sometimes given to the father and to the husband to inflict capital punishment on the wife. Of necessity, the offspring of such marriages as these were either reckoned among the stock in trade of the common-wealth or held to be the property of the father of the family; and the law permitted him to make and unmake the marriages of his children at his mere will, and even to exercise against them the monstrous power of life and death. – from Arcanum (1880)
