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).
