5.5.1 Sacrament of the Anointing of the Sick
1. The Sacrament of the Anointing of the Sick is to be conferred only by a priest and according to Pastoral Care of the Sick: Rites of Anointing and Viaticum as well as the provisions of canon law. 
2. Provided that people are not indiscriminately anointed (such as the aged who are not in a weakened condition or those who are not seriously ill), pastors, parochial administrators, rectors and chaplains are authorized to celebrate or permit the Anointing of the Sick with a large congregation (i.e., a communal celebration). 
3. The priest should always offer the Sacrament of Reconciliation prior to Anointing if the one to be anointed desires it and is able to participate.
