Eucharist

===Reception and devotions===
According to the Catholic Church doctrine receiving the Eucharist in a state of [[mortal sin]] is a [[sacrilege]]<ref>{{Cite web|url=https://www.catholicity.com/baltimore-catechism/lesson28.html|title=Holy Communion|website=www.catholicity.com}}</ref> and only those who are in a state of grace, that is, without any mortal sin, can receive it.<ref>{{cite book |title=Compendium of the Catechism of the Catholic Church # 291 |url=https://www.vatican.va/archive/compendium_ccc/documents/archive_2005_compendium-ccc_en.html |access-date=20 August 2019}}</ref> Based on 1 Corinthians 11:27–29, it affirms the following: "Anyone who is aware of having committed a mortal sin must not receive Holy Communion, even if he experiences deep contrition, without having first received [[Penance (Catholic Church)|sacramental absolution]], unless he has a grave reason for receiving Communion and there is no possibility of going to confession."<ref>{{Cite CCC|2.1|1385}}</ref><ref>{{Cite CCC|2.1|1457}}</ref>

Since the Eucharist is the body and blood of Christ, "the worship due to the sacrament of the Eucharist, whether during the celebration of the Mass or outside it, is the worship of {{lang|la|latria}}, that is, the adoration given to God alone.""<ref>{{cite web| url = https://www.vatican.va/archive/compendium_ccc/documents/archive_2005_compendium-ccc_en.html| title = Compendium of the Catechism of the Catholic Church #286}}</ref> The Blessed Sacrament can be exposed (displayed) on an [[altar]] in a [[monstrance]]. Rites involving the exposure of the Blessed Sacrament include [[Benediction]] and [[eucharistic adoration]]. According to [[Catholic theology]], the host, after the Rite of Consecration, is no longer bread, but is the Body, Blood, Soul, and Divinity of Christ. Catholics believe that Jesus is the sacrificial [[Lamb of God]] prefigured in the [[Old Testament]] [[Passover]]. Unless the flesh of that Passover sacrificial lamb was consumed, the members of the household would not be saved from death. As the Passover was the [[Old Covenant]], so the Eucharist became the [[New Covenant]]. (Matthew 26:26–28, Mark 14:22-24, Luke 22: 19–20, and John 6:48–58)
