If, then, we have died with Christ, we believe that we shall also live with him.
"The Christian meaning of death is revealed in the light of the Paschal Mystery of the Death and Resurrection of Christ in whom resides our only hope. The Christian who dies in Christ Jesus is 'away from the body and at home with the Lord' (2 Cor 5:8)."
Catechism of the Catholic Church, no. 1681
"At the death of a Christian, whose life of faith was begun in the waters of Baptism and strengthened at the Eucharistic table, the Church intercedes on behalf of the deceased because of its confident belief that death is not the end, nor does it break the bonds forged in life. The Church also ministers to the sorrowing and consoles them in the funeral rites with the comforting Word of God and the Sacrament of the Eucharist."
