In the current debate over gay marriage, people sometimes ask: Who should define marriage? De­mocrats or Republicans in Con­gress? The Supreme Court? Should it be put to a referendum, allowing the majority to choose a definition? 

We can identify two kinds of “definitions” when it comes to mar­riage. The first touches on the es­sence, the objective reality, or the truth about marriage. The second involves a legal or political position, advanced through the media, judi­cial decisions, or other legislative means. While these secondary defi­nitions of marriage can be of inter­est, their true level of importance is properly gauged only in reference to the first and objective definition.

Notable errors are sometimes made in these secondary definitions of marriage. In the mid-1960’s, to consider but one example, prohibi­tions existed in more than a dozen states which outlawed persons of different races from marrying one another. A white man and a black woman could fall in love in those states, but could not legally tie the knot. The Supreme Court over­turned those restrictions in 1967, recognizing that the ability to enter into marriage doesn’t depend on the skin color of the man and woman getting married. 

Gay marriage advocates today sometimes attempt to draw a par­allel between such mixed-race marriage laws and state laws that would prevent two men (or two women) from getting married to each other. They suggest that le­gally forbidding two men from getting married stigmatizes those men in much the same way that preventing a black man from marrying a white woman stigma­tized both of them. Yet there is really no parallel at all between the two cases. While marriage as an objective reality is certainly color-blind to the racial configu­ration of the spouses, it can never be “genital-blind,” because male-female sexual complementarity stands squarely at the heart and center of marriage itself.

To see this fundamental point about marriage, however, we have to step beyond the cul­tural clichés that suggest that marriage is merely an outgrowth of emotional and erotic compan­ionship. The institution of mar­riage does not arise merely out of loving sentiment. It is born, rather, from the depths of the commitment assumed by a man and a woman as they enter into the total communion of life im­plied in the procreation and edu­cation of children flowing from their union. To put it another way, marriage arises organi­cally and spontaneously from the radical com-plementarity of a man and a woman. 

Sexual intimacy between men and women involves the possibility of children. No other form of sexual or erotic interaction encompasses this basic, organic, and complementary possibility. Without parsing words, Professor Jacques LeClercq put it this way more than 50 years ago: “The human race is divided into two sexes whose reason for existence is physical union with a view to continuing the species.” More recently, Professor Robert P. George similarly described marriage as “a union that takes its distinctive character from being founded, unlike other friendships, on bodily unity of the kind that some­times generates new life.” There are many kinds of love, ranging from maternal love to brotherly love to love of friends to love of neighbor to romantic love, but only one that is proper and integral to marriage, namely, spousal love with its in­scribed complementarity and poten­tial for human fruitfulness.

Marriage teaches us that men need women and women need men and that children need both mothers and fathers. In this sense, marriage and the family represent foundational realities, not constructs that can be invented, defined, legislated, or de­termined by popular vote or culture. Marriage, in fact, is the “primordial first institution,” flowing out of the intimate and creative union of male and female. It precedes other societal institutions and conventions, and is essentially ordered towards creating and caring for the future in the form of the next generation. Marriage is a given reality that we come to discover in its authentic design, not a concept for us to“define” according to our own agenda or desires.

Gay marriage proponents deny these foundational truths about mar­riage. Through vigorous legislative efforts, they are striving to impose a profoundly false redesign for mar­riage upon society so that, in the words of Professor George, marriage becomes “an emotional union for the sake of adult satisfaction that is served by mutually agreeable sexual play,” thereby undermining its intrin­sic connection to complementary bodily union between men and women. This forced reconfiguration of marriage is no more defensible than the efforts of those who socially or legislatively attempted to impose a notion of “racial purity” upon mar­riage or society in former times.
