The rules of the Jewish faith do not begin and end at the door of the synagogue. In the Talmud, it is written that the first question you are asked by God on entry into heaven is, “Did you conduct your business affairs honestly?” The great commentator, Ramban, wrote that you can obey all the rules of the torah to the letter, and still be repulsive and pathetic human being. The spirit of the law must be followed not the letter.
Business ethics is the arena where the ethereal transcendent teachings of holiness and spirituality confront the often grubby business of making money and being engaged in the rat race that often comprises the marketplace. It is the acid test of whether religion is truly relevant or religion is simply relegated to an isolated sphere of human activity. It is business ethics, one could posit, above all, that shows God co-exists in the world rather than God and godliness being separate and apart.
