In this paper I provide a critical commentary of Elmer Thiessen's "The Ethics of Evangelism". Following an overview of the book's project and strategies, I discuss two stages of the project in detail. The first is Thiessen's analysis of "religious proselytism"; the second is Thiessen's arguments that evangelizing can be a good thing to do in itself. Finally, I summarize what I think are the chief merits of the book and suggest for whom it will be of particular interest. (Contains 7 notes.)
