II. The Celebration of Funerals

From The Catechism of the Catholic Church

1689
The
Eucharistic Sacrifice. When the celebration takes place in church the Eucharist
is the heart of the Paschal reality of Christian death.¹⁸⁹ In the
Eucharist, the Church expresses her efficacious communion with the departed:
offering to the Father in the Holy Spirit the sacrifice of the death and
resurrection of Christ, she asks to purify his child of his sins and their
consequences, and to admit him to the Paschal fullness of the table of the
Kingdom.¹⁹⁰ It is by the Eucharist thus celebrated that the community
of the faithful, especially the family of the deceased, learn to live in
communion with the one who “has fallen asleep in the Lord,” by
communicating in the Body of Christ of which he is a living member and, then,
by praying for him and with him.
