The Funeral Liturgy

In a literal sense, a funeral is not a sacrament as the Mass or Baptism are, but it is an occasion that cries out for prayer and worship, perhaps the deepest of our lives.
"If one member suffers in the body of Christ which is the Church, all the members suffer with that member" (1 Corinthians 12:26).

For this reason those who are baptized into Christ and nourished at the same table of the Lord are responsible for one another. When Christians are sick, their brothers and sisters share a ministry of mutual charity and "do all that they can to help the sick return to health, by showing love for the sick, and by celebrating the sacraments with them." So too when a member of Christ's Body dies, the faithful are called to a ministry of consolation to those who have suffered the loss of one whom they love. Christian consolation is rooted in that hope that comes from faith in the saving Death and Resurrection of the Lord Jesus Christ. Christian hope faces the reality of death and the anguish of grief but trusts confidently that the power of sin and death has been vanquished by the risen Lord. The Church calls each member of Christ's Body – Priest, Deacon, lay person - to participate in the ministry of consolation: to care for the dying, to pray for the dead, to comfort those who mourn."
