Authentic sacred books possess a compelling interior force that seems to open a channel of communication between this dimension of human existence and the transcendent. They have been for thousands of years the depositories of a divine wisdom and language that is not found in other type of literature. Their imperishable richness is not void of an individual and collective effort of interpretation of what those texts authentically mean. How much of the literal text is a historical account of events that happened beyond recorded time? How much of it is symbolic language that defies literal interpretation? What ethical and moral foundation do they offer as guidance for humanity's spiritual development? The ultimate question to find answers to these questions is, Who has an authoritative interpretation of those sacred texts that is truthful and accurate? This is the objective of this book-an exploration on who has such authority and how it has been manifested in past religions.
