….Infertility does not invalidate our marriage, but we constantly experience infertility as an inability to fulfill a basic aspect of marriage. It is a loss for us in a way that it can never be for a same-sex couple, who can never have expected fertility together. Our relationship is ordered toward having children, even if it is frustrated and kept from this fulfillment.
To return to Plato, love desires fecundity. Love wishes to have children with the Beloved…. Even the Greeks, despite their frequent tolerance (and sometimes even enthusiasm) for some homosexual relations, never conflated such relationships with marriage.
Love, erotic or intellectual, between two men could never be fruitful in the physical way that it could be between men and women. Physical sterility is the natural order for homosexual couples, and is dictated by their sexual proclivities, which are in direct conflict with the possibility of natural procreation.
There is a clear distinction (whether considered in ontological, teleological, or experiential terms) between homosexual couples and infertile heterosexual couples. For the latter, childlessness is not intrinsic to their relationship. Rather, whether due to illness, age, or deliberate action, it is a loss from the fullness of what their marriage should be. For those who are voluntarily sterile, it is an intentional avoidance of that fulfillment—an avoidance that has traditionally been condemned. For same-sex couples, the question does not even arise, because fertility is never a natural fulfillment of their relationship. No matter what medical advances may be made against age, illness, and injury, homosexual relations will remain intrinsically sterile.
Redefining marriage to include same-sex unions severs the connection between marriage and children in a way that recognizing the marriages of childless heterosexual couples does not. The possibility and even the desire to have children together must be discarded upfront….
