Conscience has long been a foundational theme in Christian ethics, but it is a notoriously slippery and contested term. This volume works to define conscience and reveal the similarities and differences between different Christian traditions’ thinking on the subject. In a thorough and scholarly manner, the authors explore Christian theological, legal, constitutional, historical, and philosophical meanings of conscience. Covering a range of historical periods, major figures in the development of conscience, and contemporary applications, this book is a vital source for scholars from a wide variety of disciplines seeking to understand conscience from a range of perspectives.
