While natural law theory plays an important role for Catholic moral theology, it is true that Orthodox ethics has not endeavoured to develop its own theory of natural law. This article demonstrates the existence of the concept of natural law in Eastern Orthodox theology and argues that the main reason for this neglect is Eastern Christianity’s traditional focus on faith rather than reason. In addition, the author, based on biblical and patristic grounds, highlights the necessity for a balance between the two to be found and provides a way in which Orthodox moral theology could develop a natural law theory, should it ever feel the need to do so, by first redefining its relationship with the science of philosophy, after so many years of disregard.
