Marriage is not a religious institution, but an institution that has been co-opted by religion as the means by which couples declare themselves to each other for an indefinite period. As such, marriage has always complimented contemporary attitudes and institutions. Traditional beliefs regarding the 'sanctity' of marriage are now out of touch both with contemporary opinion on the matter and concurrent advances in human rights elsewhere. In Australia a recent poll found that 75% of the population felt gay marriage was inevitable, leading marriage equality advocates to claim 'the tide of history is running toward equality and nothing can turn it back'1. Furthermore, the fact that atheists and agnostics are free to get married, but homosexuals are not undermines claims that marriage is a derivative organ of religion.  1 Wockner, Rex (2011, June 16).
