This paper argues that Ignatian principles for the discernment of spirits appear throughout Amos Yong's theology of world religions. In an effort to locate a greater Pentecostal relationship to tradition and contribute to ecumenical dialogue, the author points to three examples. First, for both Ignatius and Yong, good and evil spirits exist and interact with human persons. Second, both see divine activity in all people. This argument stems from theological considerations and stands distinct from the metaphysical considerations made in the first point. Finally, both rely on the affective as a genuine source of knowledge in discerning spirits. The argument regarding this latter point will center on a methodological consideration.
