To be Christian, I would say, is to live within the Christian tradition
as a metaphor of the sacred, and also as a sacrament of the sacred. The
tradition as a whole has as one of its main purposes mediating the reality
of the spirit or the reality of the sacred—that is, entering into
a relationship with the sacred. It's about entering into a relationship
with suchness, with is-ness. I think of God, to use very abstract language,
as is-ness without limits. Our relationship to is-ness matters profoundly.
It will shape our whole way of being in the world.

Christianity is all about?”
