Marriage is many things to lots of religions and people. And I for one certainly understand, respect and appreciate the sanctity of the Christian version of this. Knowing various married couples of different ceremonial backgrounds, I am yet to witness any great difference between them in terms of the strength of their union, either at the point of marriage, or thereafter. Maybe I am missing something though.
Having attended such a ceremony, it certainly wasn’t business or contract like - it entailed an almost identical set of commitments and values as a religious ceremony.
Maybe it is the term of ‘marriage’ you take umbridge with, which may be a wrong choice of phrase on my part.
What I am trying to get across ineptly and cursorily, was laid out perfectly by G.K. Chesterton in his What's Wrong with the World.
