I have a very realistic image of what marriage should be. It takes effort, but it shouldn't be the hardest thing that you do.
Corresponding to the image of a monotheistic God is monogamous marriage. Marriage based on exclusive and definitive love becomes the icon of the relationship between God and his people and vice versa.
It's only fair that stable gay relationships of long standing should have the same rights and responsibilities as married couples. I know the image of gay marriage is to some people horrific and ludicrous.
Images contaminate us like viruses.
Bigamy is having one wife too many. Monogamy is the same.
