Marriage is a religious institution, they argue, and not one for society to tamper with. Given that the U.S.A. is a secular nation, religion should play no role in any discussion about civil and societal laws. In order to legally marry there is absolutely no requirement for a religious ceremony to be held. In this sense, marriage is not a religious institution but a socio-legal one governed by the state. Religious beliefs about marriage should never be enshrined in laws in ways that restrict the freedom of others who do not share those beliefs.
