Dominum et Vivificantem §20

²⁰ The theophany at the Jordan clarifies only in a fleeting way the mystery of Jesus of Nazareth, whose entire activity will be carried out in the active presence of the Holy Spirit. This mystery would be gradually revealed and confirmed by Jesus himself by means of everything that he "did and taught." In the course of this teaching and of the messianic signs which Jesus performed before he came to the farewell discourse in the Upper Room, we find events and words which constitute particularly important stages of this progressive revelation. Thus the evangelist Luke, who has already presented Jesus as "full of the Holy Spirit" and "led by the Spirit...in the wilderness," tells us that, after the return of the seventy-two disciples from the mission entrusted to them by the Master, while they were joyfully recounting the fruits of their labors, "in that same hour [Jesus rejoiced in the Holy Spirit and said: 'I thank you, Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding and revealed them to babes; yea, Father, for such was your gracious will.'" Jesus rejoices at the fatherhood of God: he rejoices because it has been given to him to reveal this fatherhood; he rejoices, finally, as at a particular outpouring of this divine fatherhood on the "little ones." And the evangelist describes all this as "rejoicing in the Holy Spirit." This "rejoicing" in a certain sense prompts Jesus to say still more. We hear: "All things have been delivered to me by my Father; and no one knows who the Son is except the Father, or who the Father is except the Son and any one to whom the Son chooses to reveal him."
