It is frequently said that evangelism or proselytizing has no place in the classroom. The purpose of this essay is to counter this generalization and to explore the nature of legitimate religious influence in the classroom. In doing so I will offer some criteria to help us determine what is and what is not acceptable by way of religious persuasion in the classroom, drawing on my recent work, "The Ethics of Evangelism: A Philosophical Defence of Ethical Proselytizing and Persuasion" (2011).
