“I have still much to say to you, but it is beyond your reach as yet. It will be for him, the truth-giving Spirit, when he comes, to guide you into all truth. He will not utter a message of his own; he will utter the message that has been given to him; and he will make plain to you what is still to come. And he will bring honour to me, because it is from me that he will derive what he makes plain to you. I say that he will derive from me what he makes plain to you, because all that belongs to the Father belongs to me.” (St. John xvi, 12-15)
