¶ 653
The truth of Jesus' divinity is confirmed by his Resurrection. He had said: "When you have lifted up the Son of man, then you will know that I am he." The Resurrection of the crucified one shows that he was truly "I AM", the Son of God and God himself. So St. Paul could declare to the Jews: "What God promised to the fathers, this he has fulfilled to us their children by raising Jesus; as also it is written in the second psalm, 'You are my Son, today I have begotten you.'" Christ's Resurrection is closely linked to the Incarnation of God's Son, and is its fulfilment in accordance with God's eternal plan.
¶ 1080
From the very beginning God blessed all living beings, especially man and woman. the covenant with Noah and with all living things renewed this blessing of fruitfulness despite man's sin which had brought a curse on the ground. But with Abraham, the divine blessing entered into human history which was moving toward death, to redirect it toward life, toward its source. By the faith of "the father of all believers," who embraced the blessing, the history of salvation is inaugurated.
¶ 1081
The divine blessings were made manifest in astonishing and saving events: the birth of Isaac, the escape from Egypt (Passover and Exodus), the gift of the promised land, the election of David, the presence of God in the Temple, the purifying exile, and return of a "small remnant." the Law, the Prophets, and the Psalms, interwoven in the liturgy of the Chosen People, recall these divine blessings and at the same time respond to them with blessings of praise and thanksgiving.
¶ 1082
In the Church's liturgy the divine blessing is fully revealed and communicated. the Father is acknowledged and adored as the source and the end of all the blessings of creation and salvation. In his Word who became incarnate, died, and rose for us, he fills us with his blessings. Through his Word, he pours into our hearts the Gift that contains all gifts, the Holy Spirit.
¶ 1083
The dual dimension of the Christian liturgy as a response of faith and love to the spiritual blessings the Father bestows on us is thus evident. On the one hand, the Church, united with her Lord and "in the Holy Spirit," blesses the Father "for his inexpressible gift in her adoration, praise, and thanksgiving. On the other hand, until the consummation of God's plan, the Church never ceases to present to the Father the offering of his own gifts and to beg him to send the Holy Spirit upon that offering, upon herself, upon the faithful, and upon the whole world, so that through communion in the death and resurrection of Christ the Priest, and by the power of the Spirit, these divine blessings will bring forth the fruits of life "to the praise of his glorious grace."
¶ 1084
"Seated at the right hand of the Father" and pouring out the Holy Spirit on his Body which is the Church, Christ now acts through the sacraments he instituted to communicate his grace. the sacraments are perceptible signs (words and actions) accessible to our human nature. By the action of Christ and the power of the Holy Spirit they make present efficaciously the grace that they signify.
¶ 1085
In the liturgy of the Church, it is principally his own Paschal mystery that Christ signifies and makes present. During his earthly life Jesus announced his Paschal mystery by his teaching and anticipated it by his actions. When his Hour comes, he lives out the unique event of history which does not pass away: Jesus dies, is buried, rises from the dead, and is seated at the right hand of the Father "once for all." His Paschal mystery is a real event that occurred in our history, but it is unique: all other historical events happen once, and then they pass away, swallowed up in the past. the Paschal mystery of Christ, by contrast, cannot remain only in the past, because by his death he destroyed death, and all that Christ is - all that he did and suffered for all men - participates in the divine eternity, and so transcends all times while being made present in them all. the event of the Cross and Resurrection abides and draws everything toward life.
¶ 1086
"Accordingly, just as Christ was sent by the Father so also he sent the apostles, filled with the Holy Spirit. This he did so that they might preach the Gospel to every creature and proclaim that the Son of God by his death and resurrection had freed us from the power of Satan and from death and brought us into the Kingdom of his Father. But he also willed that the work of salvation which they preached should be set in train through the sacrifice and sacraments, around which the entire liturgical life revolves."
