What is unction and how is it used in different contexts?

Unction is a word that has several meanings depending on the context. In general, it refers to the act or process of applying something, usually a liquid or a cream, to a surface or a body part. However, unction can also have specific religious, medical, or literary connotations.
Unction as a religious rite
In some Christian traditions, unction is the practice of anointing someone with oil or ointment as a symbol of God’s grace, healing, or empowerment. For example, in the Catholic Church, unction is one of the seven sacraments and is also known as anointing of the sick or extreme unction. It is administered by a priest to a person who is seriously ill, dying, or about to undergo a major surgery. The priest makes the sign of the cross with oil on the person’s forehead and hands and says a prayer asking for God’s mercy and strength.
In some Protestant denominations, unction is also used to refer to the anointing of someone with oil for healing or spiritual purposes. For example, in James 5:14-15, the Bible instructs: “Is anyone among you sick? Let them call the elders of the church to pray over them and anoint them with oil in the name of the Lord. And the prayer offered in faith will make the sick person well; the Lord will raise them up.” Some Christians believe that this practice demonstrates faith in God’s power and promises.
Unction as a medicinal substance

In medicine, unction is another term for an ointment or a cream that is applied to the skin to treat a wound, an infection, or a condition. For example, some people use unctions that contain menthol or camphor to relieve congestion or coughs. Unctions can also be used to soothe irritation, inflammation, or pain. Unctions are usually made of oils, fats, waxes, resins, or other substances that have medicinal properties.
Unction as a literary device

In literature, unction is a way of expressing emotion or sincerity in speech or writing. It can also mean exaggerated or insincere earnestness or flattery. For example, one might say that a speaker delivered his speech with great unction, meaning that he spoke with passion and conviction. Alternatively, one might say that a writer used too much unction in his praise, meaning that he was overly flattering or fawning. Unction can also refer to the quality of being smooth or oily in manner or appearance.
