One City Under God

To what civil authorities or what government do we owe firstallegiance?  Is it our city? County?  State? Nation?  To whom must our firstallegiance be pledged?

What if my city proclaims itself opposed to murder and refusesto allow abortuaries to be established within the city limits and prohibits anyof its citizens from committing abortion? (One might imagine a resident being evicted from the city limits uponverification of the deed.)  

In other words, if the city had no authority to prosecute what it deemed to be a capital crime, might it not refuse residency to those it regarded as capital offenders to be unfit for residence at the least?

If a community cannot punish its criminals because the higher authority prohibits such actions, may it not require that the unwanted offender be removed from the company its citizens?  May it not strip him of citizenship and expel him?
