If, then, we have died with Christ, we believe that we shall also live with him." (Rom 6:8)
Because of our belief not only in the immortality of the soul, but also in the resurrection of the body, the Church professes hope in the face of death, and acts with charity in the funeral rites. The Church provides a number of prayers for the faithful to offer both to accompany the dying of a loved one and to strengthen our faith upon their death. Through private prayer and public funeral rites, we strengthen our faith and hope, comfort those who mourn, and bury the bodily remains of the deceased with care befitting what was the Temple of the Holy Spirit.

The following excerpts are taken from the General Introduction of the Order of Christian Funerals:

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.

Christians celebrate the funeral rites to offer worship, praise, and thanksgiving to God for the gift of a life which has now been returned to God, the author of life and the hope of the just. The Mass, the memorial of Christ's death and resurrection, is the principal celebration of the Christian funeral.
