On April 1st, 2001, the Netherlands became the first nation in human history to legalize same-sex marriage. Years later, in 2015, the U.S. Supreme Court likewise declared marriage a fundamental right protected by the Constitution. President Barack Obama, in a speech at the Rose Garden, declared "love is love" as he celebrated the ruling as "a victory for America." And most Americans seem to agree. A gallop poll suggests that approximately 88% of democrats and nearly 50% of Republicans support gay marriage. So it seems the debate is over. But should it be? In 2007, an Assumptionist priest by the name of Barry Bercier wrote in his book, Skies of Babylon, that if traditional marriage were re-defined to include same sex couples, "the result would be nothing less than the end of the world of man." Sound dramatic? Well -- what is marriage? If marriage were merely a proclamation of love, and if the fundamental purpose of marriage were to reward people who love each other, then gay marriage should be legal. But society does not give certain legal rights, financial benefits and tax breaks to people simply because they fall in love. At least, until two decades ago, that's not how it worked. Barry Bercier defines marriage as "the public and legal recognition of the pre-political duality of the sexes and the significance of the duality for human beings and the social and political order." In other words, marriage -- traditional marriage as it existed across every civilization for nearly all of human history, is the recognition of a unique relationship that pre-exists law and human constructs. That is, the institution of marriage - from Mesopotamia, to Egypt, China, Rome and every Western nation until 2001 -- recognized the duality of the sexes through law because the duality is the nucleus from which life emerges. The relationship between male and female -- man and woman -- whether you are gay, straight, black, white, bisexual, asexual, rich or poor, is our beginning; our source. For every human being, the duality of the sexes is our 'sine qua non' -- without it, life would not exist.
