This article explores the work of Bernadette Roberts, a little-known contemporary Catholic Christian mystic. I analyze her work as a basis for a renewed and complete Christian map of mystical consciousness for the contemporary era. Through her experience, Roberts lays the foundation for a native Christian nonduality. Nonduality (or in Christian terms, indistinct union) is not described in traditional Christian mystical maps. This article argues for the inclusion and legitimacy of nonduality in Christian spiritual life. The article then focuses on the path of individual states. A fully integral analysis of Christian spirituality would include all elements of the Integral model (i.e., quadrants, levels, lines, states, and types); this article is intended to be an introductory contribution to a much larger project.
