Abstract
ABSTRACT: Evangelism has been present in modern nursing care from the days of Nightingale in the Crimea. Even so, there is little in the way of ethical analysis and guidance regarding evangelism in healthcare. This article examines Nightingale's concern about evangelism in nursing care; discusses the boundaries established by the 2015 American Nurses Association Code of Ethics for Nurses with Interpretive Statements; and analyzes ethical issues including vocation, power, vulnerability and voluntariness, religious diversity, spiritual care, harm, and the Great Commission. Within the context of ethical analysis, broad guidelines are provided for nurses in clinical practice.
