II. How is the Liturgy Celebrated?

From The Catechism of the Catholic Church

1148
Inasmuch as they are creatures, these perceptible realities can become means of
expressing the action of God who sanctifies men, and the action of men who
offer worship to God. the same is true of signs and symbols taken from the
social life of man: washing and anointing, breaking bread and sharing the cup
can express the sanctifying presence of God and man’s gratitude toward his
Creator.
