A monstrance, also known as an ostensorium is the sacred vessel used in churches for the exhibition of the consecrated Eucharistic host during Eucharistic adoration or Benediction of the Blessed Sacrament. It is also used as reliquary for the public display of relics of some saints. The word monstrance comes from the Latin word monstrare, while the word ostensorium came from the Latin word ostendere.
