Marriage should be a sacred institution between only a woman and a man

Marriage is a holy sacrament that combines man and a woman as one in the eyes of God. When Adam and Eve were created, they formed a couple - a husband and a wife. Their main purpose here on earth is to form a family by producing children for the next generation of humanity.

Even in the Bible it is stated that relationship between man to man or woman to woman is considered a sin as what have happened to Sodom and Gomorrah. God destroyed the two cities because of its homosexual aspect of the attitude of the inhabitants.
Being a gay or lesbian is not natural born but a choice. It is an act of man resulted from the influence of the environment. It is controllable because man was given wisdom to know what is right and wrong. Even on biological terms, only two chromosomes will form the gender of a person, either male or female. Definitely there is no room for the so-called "third sex" which is gay and lesbianism.

If marriage between man to man or woman to woman will be allowed and accepted, it is just like allowing marriage between man and animal. Isn't that absurd? For even animals knew that male should be paired to female and vice-versa and not same sex.
The act of lesbianism or being a gay is basically psychological and not biological.
It can be maneuvered by mind because it is the mind that controls our body and its part, and the heart is not an exemption. Although it is a fact that because of ultra-modern technology, sex can now be transformed but the reality of what you are as natural born will always prevail. Until now, government still doesn't allow the change of gender in their birth certificate.

The holy matrimony is exclusively only between a groom and a bride not groom to groom or bride to bride. It is a union that vows to share one life together until death do them apart. And it will be sealed not only by their promises but by the blessing of God in the person of a priest or a judge.

There are three essential elements in every normal marriage: the gratification of the sexual impulse, the relation between husband and wife apart from it, and procreation. The first two elements can be possibly present to gay and lesbian relationships although it is still a debatable thing, but procreation is definitely can't be accomplished. Only a couple consisting of a natural man and woman can fully accomplish such elements therefore only man and a woman have the right to marry. For woman marries not just to be a wife but also in preparation to be a mother.

A lot of arguments can be made out of this issue but all will still result to one conclusion- the conclusion that marriage as a sacred union should exclusively be between a real man and a real woman.
