Sometimes, though, marriage has been seen as a union between one woman and several men (as in southern India, where one bride might be shared by several brothers). Marriage has also, at times, been recognized as a union between two men (as in ancient Rome, where marriages between aristocratic males were once recognized by law); or as a union between two siblings (as in medieval Europe, when valuable property was at stake); or as a union between two children (again in Europe, as orchestrated by inheritance-protecting parents or by power-wielding popes); or as a union between the unborn (ditto); or as a union between two people limited to the same social class (once more in Europe, where medieval peasants were often forbidden by law to marry their betters, in order to keep social divisions clean and orderly).
Marriage has also been seen at times as a deliberately temporary union. In modern revolutionary Iran, for instance, young couples can ask a mullah for a special marriage permit called a sigheh-a twenty-four-hour pass that permits the couple to be “married,” but just for one day. This pass allows a male and female to be safely seen in public together or even, legally, to have sex with each other-essentially creating a Koran-sanctioned, marriage-protected form of provisional romantic expression.
In China, the definition of marriage once included a sacred union between a living woman and a dead man. Such a merger was called a ghost marriage. A young girl of rank would be married off to a dead man from a good family in order to seal the bonds of unity between two clans. Thankfully, no actual skeleton-to-living-flesh contact was involved (it was more of a conceptual wedding, you could say), but the idea still sounds ghoulish to modern ears. That said, some Chinese women came to see this custom as an ideal social arrangement. During the nineteenth century, a surprising number of women in the Shanghai region worked as merchants in the silk trade, and some of them became terrifically successful businesswomen. Trying to gain ever more economic independence, such women would petition for ghost marriages rather than take on living husbands. There was no better path to autonomy for an ambitious young businesswoman than to be married off to a respectable corpse. This brought her all the social status of marriage with none of the constraints or inconveniences of actual wifehood.
Even when marriage has been defined as a union between a man and just one woman, its purposes were not always what we might assume today. In the early years of Western civilization, men and women married each other mostly for the purpose of physical safety. In the time before organized states, in the wild B.C. days of the Fertile Crescent, the fundamental working unit of society was the family. From the family came all your basic social welfare needs-not just companionship and procreation, but also food, housing, education, religious guidance, medical care, and, perhaps most importantly, defense. It was a hazardous world out there in the cradle of civilization. To be alone was to be targeted for death. The more kin you had, the safer you were. People married in order to expand their numbers of relatives. It was not your spouse who was your primary helpmeet, then; it was your entire giant extended family, operating (Hmong-like, you could say) as a single helpmeet entity in the constant combat of survival.
Those extended families grew into tribes, and those tribes became kingdoms, and those kingdoms emerged as dynasties, and those dynasties fought each other in savage wars of conquest and genocide. The early Hebrews emerged from exactly this system, which is why the Old Testament is such a family-centric, stranger-abhorring, genealogical extravaganza-rife with tales of patriarchs, matriarchs, brothers, sisters, heirs, and other miscellaneous kin. Of course, those Old Testament families were not always healthy or functional (we see brothers murdering brothers, siblings selling each other into slavery, daughters seducing their own fathers, spouses sexually betraying each other), but the driving narrative always concerns the progress and tribulations of the bloodline, and marriage was central to the perpetuation of that story.
But the New Testament-which is to say, the arrival of Jesus Christ-invalidated all those old family loyalties to a degree that was truly socially revolutionary. Instead of perpetuating the tribal notion of “the chosen people against the world,” Jesus (who was an unmarried man, in marked contrast to the great patriarchal heroes of the Old Testament) taught that we are all chosen people, that we are all brothers and sisters united within one human family. Now, this was an utterly radical idea that could never possibly fly in a traditional tribal system. You cannot embrace a stranger as your brother, after all, unless you are willing to renounce your real biological brother, thus capsizing an ancient code that binds you in sacred obligation to your blood relatives while setting you in auto-opposition to the unclean outsider. But that sort of fierce clan loyalty was exactly what Christianity sought to overturn. As Jesus taught: “If any man come to me and hate not his father, and mother, and wife, and children, and brethren, and sisters, yea, and his own life also, he cannot be my disciple” (Luke 14:26).
But this created a problem, of course. If you’re going to deconstruct the entire social structure of the human family, what do you replace that structure with? The early Christian plan was staggeringly idealistic, even downright utopian: Create an exact replica of heaven right here on earth. “Renounce marriage and imitate the angels,” instructed John of Damascus around A.D. 730, explaining the new Christian ideal in no uncertain terms. And how do you go about imitating angels? By repressing your human urges, of course. By cutting away all your natural human ties. By holding in check all your desires and loyalties, except the yearning to be one with God. Among the heavenly hosts of angels, after all, there existed no husbands or wives, no mothers or fathers, no ancestor worship, no blood ties, no blood vengeance, no passion, no envy, no bodies-and, most especially, no sex.
So that was to be the new human paradigm, as modeled by Christ’s own example: celibacy, fellowship, and absolute purity.
This rejection of sexuality and marriage represented a massive departure from any Old Testament way of thinking. Hebrew society, by contrast, had always held marriage to be the most moral and dignified of all social arrangements (in fact, Jewish priests were required to be married men), and within that bond of matrimony there had always come a frank assumption of sex. Of course, adultery and random fornication were criminalized activities in ancient Jewish society, but nobody forbade a husband and wife from making love to each other, or from enjoying it. Sex within marriage was not a sin; sex within marriage was… marriage. Sex, after all, was how Jewish babies were made-and how can you build up the tribe without making more Jewish babies?
But the early Christian visionaries weren’t interested in making Christians in the biological sense (as infants who came from the womb); instead, they were interested in converting Christians in the intellectual sense (as adults who came to salvation through individual choice). Christianity wasn’t something you had to be born into; Christianity was something that you selected as an adult, through the grace and sacrament of baptism. Since there would always be more potential Christians to convert, there was no need for anybody to sully himself by generating new babies through vile sexual congress. And if there was no need anymore for babies, then it naturally stood to reason that there was no need anymore for marriage.
Remember, too, that Christianity was an apocalyptic religion-even more so at the beginning of its history than now. Early Christians were expecting the End of Days to arrive at any moment, perhaps as early as tomorrow afternoon, so they were not especially interested in launching future dynasties. Effectively, the future did not exist for these people. With Armageddon both inevitable and imminent, the newly baptized Christian convert had only one task in life: to prepare himself for the upcoming apocalypse by making himself as pure as humanly possible.
