In order to understand the nature of intercultural learning, a literature search was conducted. Three analogous categories from theories of culture and developmental psychology provide a framework for identifying types of intercultural education and for categorizing methods to facilitate such learning. Questions for further research and for missiology are suggested.
Interpersonal relationship is suggested as a root metaphor to unite evangelical theology and educational method, so that a dialogue between the two can be initiated. This metaphor is contrasted with "organism," Mary Elizabeth Mullino Moore's root metaphor for process theology. Educational implications of biblical metaphors of interpersonal relationship are suggested.
