The purpose of this book is to compare and analyse covenantal and contractual models, which are used to arrange and order complex relationships of the business corporation. This book will show that covenant and contract are different concepts for envisioning responsible relationships, and that covenantal interpretation is superior to contractual interpretation. The difference and superiority of the covenantal model comes from its connectional understanding of human nature, the purpose of the business corporation, and moral values. Thus, this book argues that business relationships based upon making a ‘covenant’ with others expand reasonability beyond legal contract, and integrate moral commitment and theological vision into the business realm.
