The Church reminds us that:
"To rise with Christ, we must die with Christ: we must be away from the body and at home with the Lord. In that departure which is death the soul is separated from the body. It will be reunited with the body on the day of resurrection of the dead." (CCC 1005)
The Church knows that the experience of grief due to the loss of a loved one is a genuine sincere emotion. Death is a circumstance that falls upon all of us due to the consequences of sin. However, Christian death reveals a unique character that awaits us all: through Baptism, the Christian has already died with Christ sacramentally, in order to live a new life; and if we die in Christ’s grace, physical death completes this dying with Christ and so completes our incorporation into him in his redeeming act. (CCC 1010)
The Catholic Diocese of Fort Worth sponsors a grief program through a network called "Compassionate Friends." This association assists individuals and families who have experienced the loss of a loved one.
The "Compassionate Friends" handles multiple scenarios related to the loss of a loved one i.e. natural death, suicide, homicide, long-term illness, auto-accidents, etc.
