As long as Government is involved with marriage, Religion is the only reason to not allow it and should have no say. Fine you don't want to allow Adam and Steve to have a ceremony in your church, that is your right. The Government has to allow them to sign a paper saying that they are legally a corporation of 2 individuals. This to me is no different than when blacks and whites were not allowed to marry.

If the Government really does not want to allow marriage for one group then no one should be married in the secular sense and everyone should have a civil union with the exact same rights.
