Answer: From the Latin “To Show.” This is a sacred vessel used to display the Eucharist for adoration. It is usually gold, often decorated with precious stones with rays emanating from a glass in the center beneath which the Sacred Host is reserved. The monstrance is used for the ceremony of blessing with the Eucharist known as Benediction. Benediction is a paraliturgical Eucharistic service that began in the time of the Black Plague, when the Blessed Sacrament was exposed for public adoration. Soon it became a custom before returning the Blessed Sacrament to “hiding” in the tabernacle to lift it in benediction upon the adorers. A monstrance is usually used, but not necessary.
