The government has embarked on a twelve-week consultation on "gay" marriage ending on the 14th of June, with the clear intention of making marriage equally available to heterosexuals and homosexuals. Public opinion is polarised: the Pope has called the idea insidious and dangerous. Cardinal Keith O'Brien, the leader of the Roman Catholic Church in Scotland, said the "grotesque" plans would "shame the United Kingdom in the eyes of the world" if implemented. However some Quaker and Jewish leaders are in favour.
Same sex civil unions, giving all the benefits of marriage, were introduced into the UK in 2004, but it seems that is not enough - they must have actual marriage.
There are essentially two components to the case against homosexual marriage.
The first is that is weakens the institution of marriage. Marriage is a religious sacrament (one of the seven sacred sacraments; the others being: baptism, confirmation, communion, confession, holy orders and extreme unction.) Marriage is stated as a union between a man and a women for the purpose of producing children. And there was a time when a child produced out of wedlock had poor prospects - without a welfare state the mother and child would be dependent on charity at best and starve to death at worst. Marriage was a vital tool to bind a man to a woman and make sure he supported her ever after. Now, it's true that in the UK a lot of children are born out of wedlock and the taxpayer generally looks after them. But that doesn't mean it's a good idea. The taxpayer's generosity should be the last resort, not the first. Too many children are produced these days by unmarried mothers who have no means and no intention of paying their own baby's keep. The institution of marriage needs to be strengthened, not further weakened.
So marriage is an institution in trouble. Allowing homosexuals to marry diverts the institution further from its core purpose. It's quite true that some men and women marry knowing ahead of time that they will not or cannot have children. But at least they are following the intended template and a child is possible. Homosexuals marrying completely subverts the institution and renders it even weaker and more pointless.
The second argument against homosexual marriage is that it would tend to legitimise homosexuality. In the UK homosexuality was illegal until 1967. Since decriminalisation, homosexuals have been attempting to gain ever increasing acceptance of their deviant behaviour. Muscling in on the institution of marriage is just the most recent initiative aimed at embedding their perversion into society. It should be remembered that homosexuality is not normal; has no biological basis; and is generally harmful to health and well-being. Although one must accept that homosexuals did not ask to be born homosexual and we should be tolerant enough to allow them their abhorrent practices in private, that does not mean we have to accept the legitimacy of homosexuality generally. It is very much an "alternative" lifestyle and should be tolerated only on that basis.
