The first chapters of Genesis give us the story of creation. God created Adam and Eve who became the mother and father of all people. Many Christians believe that this shows an intent on the part of God that only a relationship between a man and a woman is acceptable. God made one man and one woman leaving each of them no other choice for companionship or love. Only men and women can produce children, which is taken by some to mean that God only wanted people with a heterosexual orientation to be reproduced. In terms of the beginning, non-heterosexuals do not exist. A common way of putting all this is that God created Adam and Eve not Adam and Steve. This is why churches oppose gay relationships especially in terms of marriage. Recently the Catholics and Mormons spearheaded a campaign, including many other denominations, to pass Prop. 22 officially outlawing gay marriage in California. Many other states have done the same with the guidance of their local churches. Currently only the Unitarian Universalist Association and the United Church of Christ, and recently joined by the Jewish Reform movement2, will perform marriage ceremonies for gays.
In Genesis 19:1-25we find the story of Sodom and Gomorah. It is this story which is used most often when people speak against homosexuality. We are told that God informs Abraham that he is going to destroy the cities of Sodom and Gemorrah. Abraham tries to plead with God to save Sodom but he only agrees to save his nephew Lot and his family. Two angels go to Sodom to warn Lot of its impending destruction. After Lot invites them in, a crowd of men shows up at his house and demands to see the angels so that they "...may know them."3 This has been interpreted to mean have sex with them. Lot goes outside to discourage them and instead offers them his virgin daughters. They refuse the girls and become aggressive for the men, then the angels save Lot and blind the crowd of men. The angels then tell Lot to get his family and to get out of town. As soon as they left Sodom, God burned the cities to the ground.
Many Christians believe this story to say that God destroyed the city of Sodom because of these "homosexuals" who wanted to molest the angels. They believe that those men of Sodom were guilty of a horrible sin for even wanting to have sex with other men. This story is often used to illustrate why homosexuality is so wrong. Underlying this is the feeling amongst some that since God destroyed Sodom in order to get rid of the gays there, that they are justified in trying to rid the world of gays themselves. They feel completely at ease with their hatred of gays because they believe thet God feels the same as they do. Some Christians even feel that they have a duty to try and wipe out the evil of homosexuality. Christianity has greatly influenced how society and the laws of the land treat gays based partly in a fear that God would deliver the same punishment against any society that accepts homosexuality.It is from this story that we get the words sodomy and sodomites. In 24 states sodomy is a crime punishable by everything from a simple fine to 20 years in prison.4 If Christians truly believe that God will level a society because of it*s gays, then it*s no wonder why so many of them would be against it.
Later in Genesis 38:1-10 we get a more specific view on non-procreative sex through the story of Onan. Onan had a brother, Er, who was killed by God for being wicked. Er left his widow without a child, so God commanded Onan to father a child for his brother with Ers wife. Onan did not want to do this, so in the midst of intercourse with his sister-in-law, just as he was about to ejaculate, he pulled out and did so on the ground. God became offended by Onans defiance and ended up killing him too.
This story serves to illustrate the sin of "spilling your seed". It is assumed that Onan ejaculated by masturbating himself, even though it is not stated that he did so. From this story Christians infer that any sex act which thwarts procreation is a sin. And while masturbation or coitus interuptus are considered sinful because they represent attempts at birth control, homosexual acts are considered to be as bad if not worse. This is because homosexual sex cannot result in procreation and therefore is seen, not as sex which avoids pregnancy, but as sex purely for the sake of indulgence. Consequently sex acts which could result in pregnancy, but avoid doing so, are bad. Sex acts which by their nature cannot result in pregnancy, like homosexual acts or masturbation, are seen as unnatural. St.Thomas Aquinas even went so far as to suggest that masturbation was worse than forced rape. He reasoned that even though rape was bad it could still result in procreation and so could not be viewed as a crime against nature. But since mastubation, and gay sex, could not result in procreation it does go against nature.5 It is for this reason that most Christians refer to homosexuality as being unnatural.
