V. The Sacramental Sacrifice Thanksgiving, Memorial, Presence

From The Catechism of the Catholic Church

1377
The Eucharistic presence of Christ begins at the moment of the consecration and
endures as long as the Eucharistic species subsist. Christ is present whole and
entire in each of the species and whole and entire in each of their parts, in
such a way that the breaking of the bread does not divide Christ.²⁰⁵
