Jesus promises a dynamic work of the Spirit, who guides us into truth across time. This is the fundamental conviction of catholicity: the Spirit continues to guide and lead into the future, across history, still guiding, convicting, illuminating, and revealing, which is precisely why ongoing reform is necessary. The story is still unfolding. Listening to the Spirit is not an archaeological dig for some original deposit but rather an attunement to a God with us, still speaking, still surprising, still revealing.
