168. But not only has our Lord called Himself a Vine—He has also given Himself, by the voice of the prophet, the title of a Grape-cluster—even when Moses, at the command of the Lord, sent spies to the Valley of the Cluster. What is that valley but the humility of the Incarnation and the fruitfulness of the Passion? I indeed think that He is called the Cluster, because that from the Vine brought out of Egypt, that is, the people of the Jews, there grew a fruit for the world’s good. No man, truly, can understand the Cluster as a token of the Divine Generation—or if there be any who so understand it, they leave no conclusion open but that we should believe that Cluster to have sprung from the Vine. And thus in their folly they attribute to the Father that which they refuse to believe of the Son.
