The Libertarian Party, for instance, believes that marriage should be a matter of personal liberty, not requiring permission from the state.[7][8] Individuals who align with this libertarian stance argue that marriage is a right, and that by allowing the state to exercise control over marriage, it falsely presupposes that we merely have the privilege, not the right, to marry. As an example of a right (as opposed to a privilege), those that are born in the US receive a birth certificate (certifying that they have been born), not a birth license (which would give them license so they could be born). Some Christian groups also argue that a marriage is a contract between a man and a woman presided over by God, so no authorization from the state is required.
