Wikipedia can explain better than I can why the state should control marriage, not religious institutions. You want to talk about something that will lead to a lot of pointless litigation about small things (such as people claiming there marriage was never valid since the standards for marriage licenses are decentralized) this is it. Not to mention the government needs uniform records for tax purposes, census purposes, and all kinds of other things:
http://en.wikipedia.org/wiki/Marriage_license
Every state in the United States has a requirement for marriage licenses to be obtained. A marriage is not valid, if the marriage ceremony is performed without a marriage license being previously obtained.
The requirements for obtaining a marriage license vary between states. In general, however, both parties must appear in person at the time the license is obtained; be of marriageable age (i.e. over 18 years; lower in some states with the consent of a parent); present proper identification (typically a driver's license, state ID card, birth certificate or passport; more documentation may be required for those born outside of the United States); and neither must be married to anyone else (proof of spouse's death or divorce may be required, by someone who had been previously married in some states).
Many states require 1 to 6 days to pass, between the granting of the license and the marriage ceremony. After the marriage ceremony, both spouses and the officiant sign the marriage license (some states also require a witness). The officiant or couple then files for a certified copy of the marriage license and a marriage certificate with the appropriate authority.
The requirement for marriage licenses in the U.S. has been justified on the basis that the state has an overriding right, on behalf of all citizens and in the interests of the larger social welfare, to protect them from disease or improper/illegal marriages; to keep accurate state records; or even to ensure that marriage partners have had adequate time to think carefully before marrying.
We had two bags of grass, seventy-five pellets of mescaline, five sheets of high-powered blotter acid, a salt shaker half full of cocaine, a whole galaxy of multi-colored uppers, downers, screamers, laughers…Also a quart of tequila, a quart of rum, a case of beer, a pint of raw ether and two dozen amyls. The only thing that really worried me was the ether. There is nothing in the world more helpless and irresponsible and depraved than a man in the depths of an ether binge. –Raoul Duke
It is hard to shed anything but crocodile tears over White House speechwriter Patrick Buchanan's tragic analysis of the Nixon debacle. "It's like Sisyphus," he said. "We rolled the rock all the way up the mountain...and it rolled right back down on us...." Neither Sisyphus nor the commander of the Light Brigade nor Pat Buchanan had the time or any real inclination to question what they were doing...a martyr, to the bitter end, to a "flawed" cause and a narrow, atavistic concept of conservative politics that has done more damage to itself and the country in less than six years than its liberal enemies could have done in two or three decades. -Hunter S. Thompson
