Wife, husband, child-these are not historical holdovers from a bygone era, but realities rooted in our human nature.
Commitment and sexual acts do not by themselves establish marriage-they must correspond to human nature, a reality discerned from observation and right reason. Applying this natural law, society has come to recognize that a parent should not marry their own child, that an individual should not marry their blood sibling, and that an individual should not have multiple spouses. Likewise, it shows us that an individual should not marry a member of the same sex.
Proponents of marriage between members of the same sex want us to ignore these realities of our human nature. But it is not without significance that our species has two sexes, male and female. That between these two sexes we observe differences, most obvious on a biological level, but on additional levels as well. That these differences are not contradictory, but complementary, and that from the natural biological complementarity of the sexes, new human life is brought forth. And of that new human life, we see that it is best nurtured and developed within the lasting union formed by its biological parents, who themselves grow and develop by this union. In this structure we call family, the child finds identity, protection, provision, and the inimitable loving care of a mother and a father. Proponents would have us ignore that this is the optimal environment to raise children, and that while practical considerations can sometimes prevent this from happening, it is a model we nevertheless recognize and strive toward, not away from. The nature of homosexual relations contradict these realities, and therefore marriage between members of the same sex is equally contradictory. The same can be said of bisexual relations, transgendered, foursomes, and other practices.
These are only a few of the reasons that I ask you to support legislation which protects the definition of marriage and family consistent with human nature, and oppose legislation which would cause the civil law to contradict human nature through marriage between members of the same sex, or its equivalent form, civil unions.
