Consecration is the solemn dedication to a special purpose or service, usually religious. The word consecration literally means "association with the sacred". Persons, places, or things can be consecrated, and the term is used in various ways by different groups. A synonym for to consecrate is to sanctify; a distinct antonym is to desecrate.
Images of the Buddha and bodhisattvas are ceremonially consecrated in a broad range of Buddhist rituals that vary depending on the Buddhist traditions. Buddhābhiseka is a Pali and Sanskrit term referring to these consecration rituals.
"Consecration" is used in the Catholic Church as the setting apart for the service of God of both persons and objects.
The ordination of a new bishop is also called a consecration. While the term "episcopal ordination" is now more common, "consecration" was the preferred term from the Middle Ages through the period including the Second Vatican Council (11 October 1962 – 8 December 1965).
The Vatican II document Constitution on the Sacred Liturgy n. 76 states,
Both the ceremonies and texts of the ordination rites are to be revised. The address given by the bishop at the beginning of each ordination or consecration may be in the mother tongue.
When a bishop is consecrated, the laying of hands may be done by all the bishops present.
The English text of Catechism of the Catholic Church, Second Edition, 1997, under the heading "Episcopal ordination—fullness of the sacrament of Holy Orders", uses "episcopal consecration" as a synonymous term, using "episcopal ordination" and "episcopal consecration" interchangeably. (CCC nn. 1556–1558)
The Code of Canon Law Latin-English Edition, (1983), under "Title VI—Orders" uses the term sacrae ordinationis minister "minister of sacred ordination" and the term consecratione episcopali "episcopal consecration". (CCL cc. 1012, 1014)
