This work models a creative exercise in ecclesiology based on a Latino/a practical theology of the Spirit, which designs theological discourse based on its encounter with the Spirit in human culture. Hence, it is a theology appreciative of and attentive to the "multiple matrices and intersections" of the Spirit with cultures. Garcia-Johnson offeres an appreciative and critical analysis of the uses of culture among Latino/a theologians, followed by the proposal for a postmodern Spirit-friendly cultural paradigm based on the narratives of the cross and the Pentecost. He develops a practical theology for a Latino/a postmodern ecclesiology based on three native Latino/a theological concepts: mestizaje, accompaniment, and manana eschatology. The resulting ecclesial construct-The Mestizo/a Community of Manana-reflects a transforming manana vision and models the visible cruciform community in which the transforming praxis and historical transcendence of the Christ-Spirit works from within. The work sets forth practical guidelines for implementation of the ecclesial construct in the urban context of devastated communities and offers suggestions for further development in Latino/a theology.
