Marriage is a civil ceremony, period.  If you want to wrap it in religious trappings, so be it, but in the end, what you are asking, is for the state to re-define long standing law to appease religious zealots.  As for us regularly passing laws to appease them, the only ones I can think of are the anti-abortion laws, which ultimately are to appease the same exact zealots that you are talking about.  Again, if it were Muslims acting this way, I'm betting you would be pretty upset, but because it is Christians, you make excuses.
