More than a tradition, natural marriage is an intrinsic part of man’s nature. It brings male and female together for the cohesiveness of society and the preservation of children who benefit from both a mother and a father.
Natural marriage predates the church and the state. The law doesn’t create anything. It defines what nature has already defined. Its purpose is to protect and nurture marriage, not redefine it to suit the preferences of a few.
Though procreation isn’t required for marriage, it is the expected norm. Childless couples are the exception to the rule. For homosexuals, sterility is the rule without exception. Certainly there are some fun off-label uses for sex, but the main purpose is procreation.
Nature predominately and profoundly argues for male and female natural marriage. Gay marriage is an anomaly. It is not vital in any way to the existence of society. Natural marriage, on the other hand, is indispensable.
