Catechism Section 1104 Christian liturgy not only recalls the events that saved us but actualizes them, makes them present. The Paschal mystery of Christ is celebrated, not repeated. It is the celebrations that are repeated, and in each celebration there is an outpouring of the Holy Spirit that makes the unique mystery present.

That is, she translated the essentials of revealed faith into the vocabulary of living language.

From the Apostles at the Last Supper until today, the bread and wine of Eucharist looks and feels and tastes like bread and wine in the eating and drinking.
