The astonishing ability of Christian faith to embed its truth in the life of widely diverse and endlessly changing cultures is the key to is growth, durability, and vitality through time and across geographical space.

This incarnational foundation projects Christianity into an ongoing pilgrimage, constantly asking how it finds expression and vital witness in the world’s changing history and culture.
