IV. The Liturgical Celebration of the Eucharist

From The Catechism of the Catholic Church

Because this bread and wine
have been made Eucharist (“eucharisted,” according to an ancient
expression), “we call this food Eucharist, and no one may take part in it
unless he believes that what we teach is true, has received baptism for the
forgiveness of sins and new birth, and lives in keeping with what Christ
taught.”¹⁸⁰
