Baptists, in particular, are vehemently opposed to any attempt by a secular government to create religious laws. One of the "Baptist Distinctives" (a term describing those principles that are generally held amongst all Baptists, as defined by the early Baptist confessions) is the "separation of church and state"1.
Baptists, in particular, came of age in the United States during a period of establishment churches, such as the Anglican church in Virginia. Itinerant Baptist preachers like John Leland2 were often imprisoned for "preaching without a license" and as such, early Baptists began to arrive at a consensus that the state should not be in charge of any church law, whether or it was Christian or not.
Not all Christians believe in this separation however. The Orthodox, in particular, tend to blur the lines of state and church (witness the Russian Orthodox church, for example), when there is sufficient mass to do so.
All that can be universally held is that it is no way essential to Christian doctrine that specific works, especially that which is aidaphora, should be legislated in some fashion. Indeed, the Pharisees were the ones who pushed for that, and we all know how well Jesus liked them.
1Please note: I am not taking a position on the distinctive, merely stating that it is an identifying mark of all Baptists. And yes, there is such a thing. It is called, a Baptist distinctive.
2Yes, it probably is ironic that as a Baptist in Virginia, I attended the John Leland Center for Theological Studies, and am now an Anglican. Regardless of the name of my seminary, however, John Leland is in fact a notable Baptist of the Revolutionary Period.
