Dominum et Vivificantem §6

⁶ This is also seen from the strict correlation of content and intention with the just-mentioned prediction and promise, a correlation found in the next words of the text of John: "I have yet many things to say to you, but you cannot bear them now. When the Spirit of truth comes, he will guide you into all the truth; for he will not speak on his own authority, but whatever he hears he will speak, and he will declare to you the things that are to come." In his previous words Jesus presents the; Counselor, the Spirit of truth, as the one who "will teach" and "bring to remembrance," as the one who "will bear witness" to him. Now he says: "He will guide you into all the truth." This "guiding into all the truth," referring to what the Apostles "cannot bear now," is necessarily connected with Christ's self-emptying through his Passion and Death on the Cross, which, when he spoke these words, was just about to happen. Later however it becomes clear that this "guiding into all the truth" is connected not only with the scandal of the Cross, but also with everything that Christ "did and taught." For the mystery of Christ taken as a whole demands faith, since it is faith that adequately introduces man into the reality of the revealed mystery. The guiding into all the truth" is therefore achieved in faith and through faith: and this is the work of the Spirit of truth and the result of his action in man. Here the Holy Spirit is to be man's supreme guide and the light of the human spirit. This holds true for the Apostles, the eyewitnesses, who must now bring to all people the proclamation of what Christ did and taught, and especially the proclamation of his Cross and Resurrection. Taking a longer view, this also holds true for all the generations of disciples and confessors of the Master. Since they will have to accept with faith and confess with candor the mystery of God at work in human history, the revealed mystery which explains the definitive meaning of that history.
