However traditionally licensing for marriages were regulated solely by the churches. It wasn't until the mid-1800s, in order to make laws against inter-racial marriage, that licensing by the government even appeared at all in the US. Previous to that you can find licenses issued by the churches, but no government entity.
Common law "marriage" was recognized for those who wished to simply say they were "married"...
Nowadays only 10 states recognize common law marriage, "marriage" is seen as a money maker as they collect fees for the licenses...
Again this would make it so that no benefit was tied to the religious ceremony of "marriage" if you wanted to get married you would go to a church, if you wanted the benefits of a union you would have to file the contractual agreement.
