The ten commandments ( particularly from 6 onwards) cover and initiated every law in Australia .They were given to Moses , a Jew on a mountain, thousands of years ago. So you could argue that Judaism heralded and bound our legal system and Jesus brought mateship into the Australian Psyche. This has made Australia a beautiful country to live in. It is now in jeopardy due to complacency .
These laws have brought the potential for quality relationships and sound moral foundations. When the populous ignores these we have chaos.
