Keywords: gay marriage, utilitarianism, relativism Gay Marriage What goes through one’s mind on the sight of two guys walking in the park while holding hands? The contemporary society is founded on recreating and improving itself to reach an ideal status. However, the situation of gay marriage has not been fully accepted in society and most of the people want it to be eliminated. According to the ethical perspective there are two sides that have an equal argument. There are those that favor gay marriage and those that oppose it. Those who support it base their arguments on civil rights, human needs and justice (Stanton, 2009). On the other hand, those who are against it use the deontological view that is not weighty. This paper states that the most ethical decision is to legalize gay marriage. Ethical Problems Facing Gay Marriage The major argument against gay is that marriage goes against the Bible. It violates the natural order that is recognized by God, and is highly sinful. According to the Bible, marriage was a union established by God between our first parents Adam and Eve. In the book of Genesis “God created man in His image; in the Divine image he created him; male and female He created them. God blessed them, saying: ‘Be fertile and multiply; fill the earth and subdue it.” (Genesis 1:28-29) (Cline, 2013). The Bible stipulates that marriage should be between man and woman hence gay marriage is considered to be a sin. The Bible goes ahead to demonstrate that it is punishable by God. “The Lord rained down sulphurous fire upon Sodom and Gomorrah. He overthrew those cities and the whole Plain, together with the inhabitants of the cities and the produce of the soil.” (Genesis 19:24-25) (Cline, 2013). There is much controversy surrounding gay marriage due to the fact that there are numerous ethical arguments against it. Gay marriage is not considered to be a genuine marriage regardless of it being referred to as ‘marriage’. Over the years, marriage has always been a convention between man and woman which is ordered by nature towards procreation, bringing up of children and the well being of the partners. Champions of same sex marriage have a different argument. They propose a covenant between two people of the same sex (Cline, 2013). This is because it denies the general purpose of marriage which is perpetuation of the human race and bringing up children. Additionally, it denies the obvious biological and physiological differences between man and woman. It is argued that gay marriage violates natural law since marriage is a relationship that is entrenched in human nature and governed by natural law. The most basic precept of natural law is that good acts should be promoted and evil should be avoided at all costs. Thereby, man can set what is morally acceptable or not (Cline, 2013). Situations that promote unnatural acts are viewed as being morally wrong since they go against natural law and norms of morality. Natural law is universal and deeply rooted in human nature and applies to the entire human race. Gay marriage is wrong according to natural law. Gay marriage denies a child the right to be brought up in the conventional family set up of a father and a mother.
