'...the purpose of sexual difference and the call to union is not only to reproduce the human species, although that an essential part of it. It's not only for the sake of human companionship, although that, too, is an essential part of it. The ultimate purpose of sexual difference and the call to union is signify the difference and call to union of the Creator and the creature, of Christ and his Church.'
