V. The Sacramental Sacrifice Thanksgiving, Memorial, Presence

From The Catechism of the Catholic Church

1378
Worship of the Eucharist. In the liturgy of the Mass we express our faith in
the real presence of Christ under the species of bread and wine by, among other
ways, genuflecting or bowing deeply as a sign of adoration of the Lord.
“The Catholic Church has always offered and still offers to the sacrament
of the Eucharist the cult of adoration, not only during Mass, but also outside
of it, reserving the consecrated hosts with the utmost care, exposing them to
the solemn veneration of the faithful, and carrying them in procession.”²⁰⁶
