We find ourselves on the threshold of the Paschal events.

The new, definitive revelation of the Holy Spirit as a Person who is the gift is accomplished at this precise moment.

The Paschal events – the Passion, Death and Resurrection of Christ – are also the time of the new coming of the Holy Spirit, as the Paraclete and the Spirit of truth.

They are the time of the “new beginning” of the self-communication of the Triune God to humanity in the Holy Spirit through the work of Christ the Redeemer.

[…] On the day of the Resurrection…Jesus of Nazareth “descended from David according to the flesh”, as the Apostle Paul writes, is “designated Son of God in power according to the Spirit of holiness by his Resurrection from the dead” (Rom. 1:3f).

It can be said therefore that the messianic “raising up” of Christ in the Holy Spirit reaches its zenith in the Resurrection, in which he reveals himself also as the Son of God, “full of power”.

And this power, the sources of which gush forth in the inscrutable Trinitarian communion, is manifested, first of all, in the fact that the Risen Christ does two things:

On the one hand he fulfills God’s promise already expressed through the Prophet’s words: “A new heart I will give you, and a new spirit I will put within you,…my spirit” (Ez 36:26f);

And on the other hand he fulfills his own promise made to the Apostles with the words: “If I go, I will send him to you” (Jn 16:7).

It is he: the Spirit of truth, the Paraclete sent by the Risen Christ to transform us into his own risen image.

[…] There is no sending of the Holy Spirit (after original sin) without the Cross and the Resurrection: “If I do not go away, the Counselor will not come to you” (Jn 16:7).

There is also established a close link between the mission of the Holy Spirit and that of the Son in the Redemption.

The mission of the Son, in a certain sense, finds its “fulfillment” in the Redemption. The mission of the Holy Spirit “draws from” the Redemption: “He will take what is mine and declare it to you” (Jn 16:15).

The Redemption is totally carried out by the Son as the Anointed One, who came and acted in the power of the Holy Spirit, offering himself finally in sacrifice on the wood of the Cross.

And this Redemption is, at the same time, constantly carried out in human hearts and minds – in the history of the world – by the Holy Spirit, who is the “other Counselor”.
