I. The Father-Source and Goal of the Liturgy

From The Catechism of the Catholic Church

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.
