703. How is pastoral care provided to the relatives of a dying person?

It is also important to provide pastoral care to the relatives of a dying person. In this phase when they begin to realise that they will have to lose a loved one, they are to experience the secure feeling that they have not been abandoned. Praying together is especially strengthening to them in this situation.
The certainty of a reunion helps to bear the heavy burden of bidding farewell. It is also helpful to family members when they are made aware of what they can do for the dying.
