Economics provides a deeper understanding of the Holy Scriptures. Not only does it justify tangible commandments like working in the sweat of your brow and giving two tithes, but it also explains why the last will be first, and the first will be last. In economics, the joy over the repentant sinner is really greater than the joy over the ninety-nine righteous. Economic equilibrium can distinguish genuine righteousness from the Pharisees' demonstrative righteousness. It also separates the kingly matter of concern from the divine one. At equilibrium, ‘the other cheek’ really doesn’t challenge ‘an eye for an eye and a tooth for a tooth’ and confirms the continuity between the Old and New Testaments. Economics can uncover the origins of the Sermon on the Mount in Solomon's Judgement. The book will put readers in touch with the best economic guesses of the past, when Luca Pacioli considered the golden ratio to be the divine proportion and Adam Smith brought up the divine origin of the invisible hand of the market.
