+Jn 16: 5-11
But now I am going to the one who sent me, and not one of you asks me, ‘Where are you going?’
But because I told you this, grief has filled your hearts.
But I tell you the truth, it is better for you that I go. For if I do not go, the Advocate will not come to you. But if I go, I will send him to you.
And when he comes he will convict the world in regard to sin and righteousness and condemnation:
sin, because they do not believe in me;
righteousness, because I am going to the Father and you will no longer see me;
condemnation, because the ruler of this world has been condemned.
The New American Bible
The Catechism of the Catholic Church
729 Only when the hour has arrived for his glorification does Jesus promise the coming of the Holy Spirit, since his Death and Resurrection will fulfill the promise made to the fathers. The Spirit of truth, the other Paraclete, will be given by the Father in answer to Jesus’ prayer; he will be sent by the Father in Jesus’ name; and Jesus will send him from the Father’s side, since he comes from the Father. The Holy Spirit will come and we shall know him; he will be with us for ever; he will remain with us. The Spirit will teach us everything, remind us of all that Christ said to us and bear witness to him. The Holy Spirit will lead us into all truth and will glorify Christ. He will prove the world wrong about sin, righteousness, and judgment.
CONFIRMATION IN THE ECONOMY OF SALVATION
1286 In the Old Testament the prophets announced that the Spirit of the Lord would rest on the hoped-for Messiah for his saving mission. The descent of the Holy Spirit on Jesus at his baptism by John was the sign that this was he who was to come, the Messiah, the Son of God. He was conceived of the Holy Spirit; his whole life and his whole mission are carried out in total communion with the Holy Spirit whom the Father gives him “without measure.”
1287 This fullness of the Spirit was not to remain uniquely the Messiah’s, but was to be communicated to the whole messianic people. On several occasions Christ promised this outpouring of the Spirit, a promise which he fulfilled first on Easter Sunday and then more strikingly at Pentecost. Filled with the Holy Spirit the apostles began to proclaim “the mighty works of God,” and Peter declared this outpouring of the Spirit to be the sign of the messianic age. Those who believed in the apostolic preaching and were baptized received the gift of the Holy Spirit in their turn.
1288 “From that time on the apostles, in fulfillment of Christ’s will, imparted to the newly baptized by the laying on of hands the gift of the Spirit that completes the grace of Baptism. For this reason in the Letter to the Hebrews the doctrine concerning Baptism and the laying on of hands is listed among the first elements of Christian instruction. The imposition of hands is rightly recognized by the Catholic tradition as the origin of the sacrament of Confirmation, which in a certain way perpetuates the grace of Pentecost in the Church.”
1289 Very early, the better to signify the gift of the Holy Spirit, an anointing with perfumed oil (chrism) was added to the laying on of hands. This anointing highlights the name “Christian,” which means “anointed” and derives from that of Christ himself whom God “anointed with the Holy Spirit.” This rite of anointing has continued ever since, in both East and West. For this reason the Eastern Churches call this sacrament Chrismation, anointing with chrism, or myron which means “chrism.” In the West, the term Confirmation suggests that this sacrament both confirms and strengthens baptismal grace.
