The well known Christian symbol, Ichthys or the fish is probably more popular today than ever with versions on the bumpers of thousands of cars, as well as sarcastic variations like the Darwin fish with legs.  But what does it stand for.
    Most Christian churches say that the Greek word for fish, ΙΧΘΥΣ, is an acronym.  The letters standing for the first letters in Greek of the phrase "Jesus Christ God's Son Saviour".   
    Astrologers say that Jesus entered the world in the age of Pisces, the astrological fish symbol, and that is why the fish started being used to represent Jesus.  
    All of these interpretations seem to ignore one thing.  The symbol used is not the way most would draw a fish.  It is simply two overlapping arcs, parts of circles.  The tail is usually left open.  Why isn't a simple straight line added to finish the tail?  One theory is that the correct way to complete the symbol is to continue the two arcs to form two overlapping circles.  This would symbolize that Christ came to unite the two halves of our being and our world.  To unite the dark and the Light, the material and the spiritual, the soul and the mind.
