I suggest you read up on the history of marriage. It was the Christians who originally redefined marriage, back in Roman times.
"While it is a relatively new practice to frequently grant same-sex couples the same form of legal marital recognition as commonly granted to mixed-sex couples, there is a long history of recorded same-sex unions around the world. It is believed that same-sex unions were celebrated in Ancient Greece and Rome, some regions of China, such as Fujian, and at certain times in ancient European history."

No religion has the monopoly on marriage, and why should they? Not everyone believes in the same religion, and even if it were true that the original marriage was between a man and a woman, tradition is the worst form of argument for supporting something. I don't support gay marriage because it was "legal" in ancient times; I support it because it is fair and equal.
