218. What is the liturgy?
The liturgy is the celebration of the mystery of Christ and in particular his paschal mystery. Through the exercise of the priestly office of Jesus Christ the liturgy manifests in signs and brings about the sanctification of humankind.
The public worship which is due to God is offered by the Mystical Body of Christ, that is, by its head and by its members.
219. What place does the liturgy occupy in the life of the Church?
The liturgy as the sacred action par excellence is the summit toward which the activity of the Church is directed and it is likewise the font from which all her power flows. Through the liturgy Christ continues the work of our redemption in, with and through his Church.
220. In what does the sacramental economy consist?
The sacramental economy consists in the communication of the fruits of Christ’s redemption through the celebration of the sacraments of the Church, most especially that of the Eucharist, “until he comes” (1 Corinthians 11:26).
THE LITURGY – WORK OF THE MOST HOLY TRINITY
221. In what way is the Father the source and the goal of the liturgy?
Through the liturgy the Father fills us with his blessings 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.
222. What is the work of Christ in the liturgy?
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.
223. How does the Holy Spirit work in the liturgy of the Church?
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.
