V. The Sacramental Sacrifice Thanksgiving, Memorial, Presence

From The Catechism of the Catholic Church

1370
To the offering of Christ are united not only the members still here on earth,
but also those already in the glory of heaven. In communion with and
commemorating the Blessed Virgin Mary and all the saints, the Church offers the
Eucharistic sacrifice. In the Eucharist the Church is as it were at the foot of
the cross with Mary, united with the offering and intercession of Christ.
