One of the areas of applied ethics in the professional dimension is " propagating ethics", which covers various areas of advertising. In the meantime, propagating religion in the efficiency and effectiveness and attracting the maximum audience, requires the religious ethics of propaganda. This article uses a descriptive-analytical method to express the characteristics of a professional missionary in its mission. The study clarifies that a missionary, in addition to his theological skills and being a "problem-finder" in observing doubts, should be pioneering in self-creation and moral interaction. The inference and analysis of the components of the "model of communication ethics" effective in propagating the Shiite school with emphasis on the teachings of Razavi, is one of the important issues and findings of this study. These components are: peaceful dialogue "inside religion" and "outside religion"; Strengthening "emotional intelligence" (EQ); Assessment of needs and capacity of the audience (familiarity with the needs and language of the recipients); Invitation to religion by penetrating into the hearts rather than orally; Avoidance of Bias and commitment to rationality; and showing affection and respect for anyone who disagrees.
