This essay explores the concept of “mutuality” through the relationship between Jesus and his mother, Mary, as a model for theology and public life. It presents female-maternal-embodied knowledge as a framework to understand the eight stages of the female maternal body, from birth to death. The essay highlights how Mary’s consent, relational autonomy, and the Incarnation exemplify transformative and intergenerational mutuality. It examines key scenes in their relationship, showing the shifts in agency, power, and reflexivity, including the need for “mutual distancing” during Jesus’ public ministry. The essay then applies this model to missiology, noting how it can inform discussions around power dynamics, financial dependency, and the challenge of “letting go” in Christian institutions. It also suggests the relevance of this model for intercultural communication, family life, congregational studies, and the one’s individual path of transformation. Ultimately, the essay proposes that the relationship between Jesus and Mary serves as a profound example of transforming mutuality, which has the potential to invigorate theology, biblical studies, and practical applications for public life.
