Anointing of the Sick
Catholic sacrament for the seriously ill or dying; a set phrase used in religious contexts.
The Anointing of the Sick is one of the seven sacraments of the Catholic Church.
終油 is an older term for the same sacrament, historically called 'Extreme Unction', while 病者の塗油 reflects the modern Catholic understanding that it is not only for the dying.
A direct translation of the Catholic term 'Anointing of the Sick', composed of 病者 (sick person) + の (possessive particle) + 塗油 (anointing with oil).
