*I also posted a slightly edited version of this message on the "Still Vomiting All Over Myself..." Thread.
I hear cries from our beloved moderators to attempt to educate our fellow member as to why his arguments are incorrect. Very well, I shall attempt to do my best with the knowledge I have.
I feel one comment I must get out of the way, and in effort protect my hypothetical ass on not being called out as a hypocrite, The Vatican has stated that the Story of Adam and Eve is allegorical, meaning not accepted canon of the Catholic Church. In essence, they still believe God created humanity but no longer believe that Adam was created from dust and Eve from a rib. Their official stance has yet to be confirmed. There, now onto the educational portion of tonight's programme:
Since the creation of the human race, be it by Divine Will or by the scientific methods presented to us, we have been a changing race.
As such, it seems that change is a constant in the world in which we live. One can simply look at the "institution of marriage" itself to see change and adaption in action.
We don't know what "caveman" wedding practices we like, if they had them or not. Or if it was the ideal of communinity systems in which everyone slept with who they wanted to. However, we can look at weddings as they evolved.
People talk of marriage between ONE man and ONE woman. What about the years in which polygamy was considered not only proper, but encouraged? Many societies engaged in the idea of one man with MANY women, but that is now frowned down upon.
As for the Bible advocating the purpose of marriage is to have children, look at Abraham and Sarah. They couldn't have children, so Abraham broke his marital bonds and slept with a slave girl. Obviously, since God did not strike him down, this is surely an endorsement of God supporting adultery for the sake of children.
The next greatest example comes from that of Jesus Christ himself. Jesus was not born of this earth, according to the New Testament. Rather, Mary was impregnated by the Holy Spirit of God, rather than by her husband. To further beat the matter with a stick, there is no evidence or support that Mary and Joesph had children of their own, that Jesus was the single child in the family. As such, we see again a marriage that resulted in no children. Therefore, the argument that men and women marry to create offspring, is a flawed argument from a religious standpoint.
The next problem comes later on in the evolution of marriage, in terms of later years. Polygamy was gone, but a new trend was sweeping the marriage world. Older men, marrying much younger women. In the times of the Marquis de Sade, it was not uncommon to see a man in his 30s or 40s (or older), married to a woman who was not yet 18.
And then, of course. There is the arranged marriage. This can probably be said to be the only form of marriage that encourages starting a family, as parents hope their children with procreate from the union, and not to mention profit off a nice wedding dowry.
Eventually, marriage evolved again (with legal assistance of course), requiring age limits or parental consent, to what we see as it's current form.
Marriage is not set in stone like most people who look back believe. They look as far back as our "Traditional Idea" of marriage, but fail to look further back to see how much it has changed during humanity's short time on this planet.
Hence, gay marriage is another step in the evolution of marriage. We are not seeking to replace "traditional marriage" but allow it to open to the alternative lifestyle.
Marriage has changed constantly over the years and centuries since people began taking ceremonies to create a solemn vow to one another, and in the end that's what marriage is. Marriage is a life long committment to another person, promising to be there for them through thick and thin. To stand by, and support them when they need help, as long as they'll do the same for you. Not to mention the legal benefits of actual marriage, such as insurance coverage and other rights. Sure, straight couples can produce children, but that is not the overall purpose of marriage.
If anyone can logically argue against those reasonings, I welcome it.
