What is truth? How should we define it? Should we define it christologically as Jesus did when he revealed himself to Thomas as the embodiment of truth, or should we appeal to philosophy for help? This book explores possible answers to these questions. More specifically, the book offers a brief survey of how different philosophical theories have attempted to define truth. After finding them somewhat incomplete, the book shows how an adequate account of truth is given by the Judeo-Christian tradition's view of omniscience. By drawing from the rich tradition of the church fathers, the book notes how naturalistic views of truth fail to account for the existence of truth prior to the evolution of the human mind. This problem, however, is a non-issue for a theistic account of truth and makes a strong case for the existence of objective truth even before the human mind was designed.
