Utah is not a theocracy. There is a clear line of separation in the Constitution of church and state. A marriage license, has been, since its inception in the early 1900s, a legal contract between a couple and the state of issuance. Nowhere in the U.S. is it mandatory to have a religious ceremony in order to legitimize or legalize a marriage.
Likewise, there is no legal standing for anyone to sue a church over their decision to not marry anyone in particular. The Constitution protects both the secular and non-secular. The gay marriage issue has nothing to do with any church; It is a state issue and the sooner our government remembers they are not a ruling theocracy the better.
Not only will denying same-sex couples the right to marry be cruel and unjust, all the "rainy day money" Utah has saved to go to social service programs and education will be eaten up in lengthy, protracted lawsuits that they will lose, just like California did. There is a homeless shelter in Provo that needs funding to open, Salt Lake City has youth living on the streets and there are families not eating three meals a day. Utah has bigger issues than gay marriage and I suggest we use our state funds in more productive, humanitarian ways.
