It is destructive because we fail to view marriage in the context of a vocation: a calling to participate in the great enterprise of forming the next generation.Actually, no. Marriage is not just for "forming the next generation." If a man and woman get married who are incapable of having children, their marriage is NOT an empty honor. It will still (ideally) be a relationship built on love, trust, and respect. It will still be a visible commitment to the world of that relationship. It will be an opportunity to deepen their love, trust and respect for each other. It will be many things, but it will not be empty. Children are not the be-all and end-all of marriage, they aren't even the most important part of it. Marriage is not a job, it is not a calling, it's a relationship.
Marriage is reduced to an empty honor.
If marriage is just a job for creating kids, then who cares if you commit adultery? Just make sure you don't have kids doing it. If marriage is just a job for creating kids, then why not arrange marriages with an eye toward breeding kids with the traits we want? You know, like horse breeding. Indeed, if marriage is just a job for creating kids, let's start having interviews, and deny you marriage if you don't pass. You can put forth your qualifications in a resume: "good at child discipline, and believe in strict bedtimes." Don't forget periodic reviews! "Your child disobeyed an average of 2 times per week last quarter. What do you plan on doing to correct this trend?"
Marriage is a relationship. Whether it is good or bad has nothing to do with the gender of those involved. So how about we start showing a little fairness?
