The article takes as point of departure the influential book An Interpretation of Religion by John Hick both to understand an Afro-Brazilian religion called Candomblé and to suggest a way to define this human activity as a whole. After a description of Hick’s proposal, his ideas will be applied to Candomblé to see what kind of religion it is. From the problems raised in this classification, the article puts forward two formal refinements in Hick’s proposal, which can increase its internal coherence as well. In addition, in view of a salient feature of Candomblé, it is argued that the concept of religion should include the experience of evil as an essential element. The resulting definition is justified by its explanatory power, amplitude and fruitfulness.
