"after all our diligence, to the end of our lives and to the end of the Church"

Scripture "cannot, as it were, be mapped, or its contents catalogued; but after all our diligence, to the end of our lives and to the end of the Church, it must be an unexplored and unsubdued land, with heights and valleys, forests and streams, on the right and left of our path and close about us, full of concealed wonders and choice treasures."
