221. In what way is the Father the source and the goal of the liturgy?Through the liturgy the Father fills us with his blessing in the Word made flesh who died and rose for us and pours into our hearts the Holy Spirit. At the same time, the Church blesses the Father by her worship, praise, and thanksgiving and begs him for the gift of his Son and the Holy Spirit.

In the liturgy of the Church, it is his own paschal mystery that Christ signifies and makes present. By giving the Holy Spirit to his apostles he entrusted to them and their successors the power to make present the work of salvation through the Eucharistic sacrifice and the sacraments, in which he himself acts to communicate his grace to the faithful of all times and places throughout the world.

The very closest cooperation is at work in the liturgy between the Holy Spirit and the Church. The Holy Spirit prepares the Church to encounter her Lord. He recalls and manifests Christ to the faith of the assembly. He makes the mystery of Christ really present. He unites the Church to the life and mission of Christ and makes the gift of communion bear fruit in the Church.
