V. The Sacramental Sacrifice Thanksgiving, Memorial, Presence

From The Catechism of the Catholic Church

1363
In the sense of Sacred Scripture the memorial is not merely the recollection of
past events but the proclamation of the mighty works wrought by God for
men.¹⁸² In the liturgical celebration of these events, they become in a
certain way present and real. This is how Israel understands its liberation
from Egypt: every time Passover is celebrated, the Exodus events are made
present to the memory of believers so that they may conform their lives to
them.
