Defending Christian marriage

[A] law of marriage just to all, and the same for all, was enacted by the abolition of the old distinction between slaves and free-born men and women; and thus the rights of husbands and wives were made equal: for, as St. Jerome says, “with us that which is unlawful for women is unlawful for men also, and the same restraint is imposed on equal conditions.” The self-same rights also were firmly established for reciprocal affection and for the interchange of duties; the dignity of the woman was asserted and assured; and it was forbidden to the man to inflict capital punishment for adultery, or lustfully and shamelessly to violate his plighted faith.
 
It is also a great blessing that the Church has limited, so far as is needful, the power of fathers of families, so that sons and daughters, wishing to marry, are not in any way deprived of their rightful freedom; that, for the purpose of spreading more widely the supernatural love of husbands and wives, she has decreed marriages within certain degrees of consanguinity or affinity to be null and void; that she has taken the greatest pains to safeguard marriage, as much as is possible, from error and violence and deceit; that she has always wished to preserve the holy chasteness of the marriage bed, the security of persons, the honor of husband and wife, and the sanctity of religion. Lastly, with such foresight of legislation has the Church guarded its divine institution that no one who thinks rightfully of these matters can fail to see how, with regard to marriage, she is the best guardian and defender of the human race; and how, withal, her wisdom has come forth victorious from the lapse of years, from the assaults of men, and from the countless changes of public events.
 
Yet, owing to the efforts of the archenemy of mankind, there are persons who, thanklessly casting away so many other blessings of redemption, despise also or utterly ignore the restoration of marriage to its original perfection. It is a reproach to some of the ancients that they showed themselves the enemies of marriage in many ways; but in our own age, much more pernicious is the sin of those who would fain pervert utterly the nature of marriage, perfect though it is, and complete in all its details and parts. The chief reason why they act in this way is because very many, imbued with the maxims of a false philosophy and corrupted in morals, judge nothing so unbearable as submission and obedience; and strive with all their might to bring about that not only individual men, but families, also – indeed, human society itself – may in haughty pride despise the sovereignty of God.
 

Now, since the family and human society at large spring from marriage, these men will on no account allow matrimony to be the subject of the jurisdiction of the Church. Nay, they endeavor to deprive it of all holiness, and so bring it within the contracted sphere of those rights which, having been instituted by man, are ruled and administered by the civil jurisprudence of the community. Wherefore it necessarily follows that they attribute all power over marriage to civil rulers, and allow none whatever to the Church; and, when the Church exercises any such power, they think that she acts either by favor of the civil authority or to its injury. Now is the time, they say, for the heads of the State to vindicate their rights unflinchingly, and to do their best to settle all that relates to marriage according as to them seems good. – from Arcanum (1880)
