Can a priest administer last rites to himself? In Catholicism, is a priest allowed to administer the "last rites" to himself (assuming no one else is there to do it for him)?
A priest could consecrate a host and administer himself Viaticum (last Holy Communion before his death). A priest cannot absolve himself, but he could make an act of perfect contrition. Extreme unction is performed by a priest on a sick person with the use of reason.
