Blood of Christ
Prayers to Jesus
Blood of Christ in Christian theology refers to (a) the physical blood actually shed by Jesus Christ from the foreskin and later on the Cross, and the salvation which Christianity teaches was accomplished thereby; and (b) the sacramental blood present in the Eucharist, which is considered by Catholic, Orthodox, Anglican, and Lutheran Christians to be the same blood of Christ shed on the Cross. The Catholic Church, as well as the Eastern Orthodox, Oriental Orthodox, Anglican, and Lutheran churches, believe that in the Eucharist, the faithful receive Jesus' literal blood under the species of wine.
The Catholic Church, Eastern Orthodox churches, the Oriental Orthodox churches, the Assyrian Church of the East, and Lutherans, together with some Anglicans, believe in the Real Presence of Christ in the Eucharist. The Catholic Church uses the term "Transubstantiation" to describe the change of the bread and wine into the body and blood of Christ. Eastern Orthodox too have authoritatively used the same term to describe the change, as in The Longer Catechism of The Orthodox, Catholic, Eastern Church and in the decrees of the 1672 Synod of Jerusalem.
The Lutheran churches follow the teaching of Martin Luther in defining the presence of Christ in the Eucharistic elements as sacramental union (often misconstrued as consubstantiation), meaning that the fundamental "substance" of the body and blood of Christ are literally present alongside the substance of the bread and wine, which remain present. Lutherans too believe in and teach the Real Presence. Most Protestant churches reject the idea of the Real Presence; they observe Eucharistic rites as simply memorials.
In the early Church, the faithful received the Eucharist in the form of consecrated bread and wine. Saint Maximus[disambiguation needed] explains that in the Old Law the flesh of the sacrificial victim was shared with the people, but the blood of the sacrifice was merely poured out on the altar. Under the New Law, however, Jesus' blood was the drink shared by all of Christ's faithful. St. Justin Martyr, an early Church father of the 2nd century, speaks of the Eucharist as the same body and blood of Christ that was present in His Incarnation.
The tradition continued in the Church in the East to commingle the species of bread and wine, whereas in the West, the Church had the practice of communion under the species of bread and wine separately as the custom, with only a small fraction of bread placed in the chalice. In the West, the communion at the chalice was made less and less efficient, as the dangers of the spread of disease and danger of spillage (which would potentially be sacrilegious) were considered enough of a reason to remove the chalice from common communion altogether, or giving it on only special occasions. However, it was always consecrated and drunk by the priest, regardless of whether or not the laity partook. This was one of the main issues in the Protestant Reformation. As a consequence, the Catholic Church first wanted to eliminate ambiguity, reaffirming that Christ was present both as body and as blood equally under both species of bread and wine. As time went on, the chalice was made more available to the laity. After the Second Vatican Council, the Catholic Church gave a full permission for all to receive communion from the chalice at every Mass involving a congregation, at the discretion of the priest.

Roman Catholic 
The Catholic Church teaches that the bread and wine, through transubstantiation, become the body, blood, soul and divinity of Christ— in other words, the whole Christ— when consecrated. Precious Blood Prayer: May the most Precious Blood which flowed from the most Holy wounds of our loving Lord Jesus pour over us, to wash, cleanse, purify, heal, guide, and protect us from all evil, harm, sickness, and bless and make us as Holy as we can be. We ask this in the Holy name of Jesus and through His most Precious Blood and His most Holy wounds. Amen.
The devotion to the Precious Blood was an especial phenomenon of Flemish piety in the fifteenth and sixteenth centuries, that gave rise to the iconic image of Grace as the "Fountain of Life," filled with blood, pouring from the wounded "Lamb of God" or the "Holy Wounds" of Christ. The image, which was the subject of numerous Flemish paintings was in part spurred by the renowned relic of the Precious Blood, which had been noted in Bruges at least since the twelfth century and which gave rise, from the late thirteenth century, to the observances, particular to Bruges, of the procession of the "Saint Sang" from its chapel.

Eastern Orthodox 
The Orthodox teach that what is received in Holy Communion is the actual Resurrected Body and Blood of Jesus Christ. In the West, the Words of Institution are considered to be the moment at which the bread and wine become the Body and Blood of Christ. But for the Orthodox there is no one defined moment; rather, all that Orthodox theology states is that by the end of the Epiklesis, the transformation has been completed. The Orthodox also do not use the theological term Transubstantiation to define the conversion from bread and wine into the Body and Blood of Christ, they use the word metaousia without the precise theological elaboration that accompanies the term trabsubstantiation..
According to Saint John Damascene, the Sacred Mysteries (under the form of bread and wine) do not become incorruptible until they are actually received in faith by a believing Christian in a state of grace.
In the Eastern Orthodox churches, and those Eastern Catholic Churches which follow the Byzantine Rite, there is no individual devotion to the Blood of Christ separate from the Body of Christ, or separated from the reception of Holy Communion.
When receiving Holy Communion, the clergy (deacons, priests and bishops) will receive the Body of Christ separately from the Blood of Christ. Then, the remaining portions of the consecrated Lamb (Host) is divided up and placed in the chalice and both the Body and Blood of Christ are communicated to the faithful using a liturgical spoon (see also Intinction).

- "The bread and wine are changed, or transubstantiated, into the very Body of Christ, and into the very Blood of Christ" (question 339).
- "In the celebration (of the Eucharist) we believe the Lord Jesus Christ to be present, not typically, nor figuratively, nor by superabundant grace, as in the other Mysteries, nor by a bare presence, as some of the Fathers have said concerning Baptism, or by impanation, so that the Divinity of the Word is united to the set forth bread of the Eucharist hypostatically, as the followers of Luther most ignorantly and wretchedly suppose, but truly and really, so that after the consecration of the bread and of the wine, the bread is transmuted, transubstantiated, converted and transformed into the true Body Itself of the Lord, Which was born in Bethlehem of the ever-Virgin, was baptized in the Jordan, suffered, was buried, rose again, was received up, sitteth at the right hand of the God and Father, and is to come again in the clouds of Heaven; and the wine is converted and transubstantiated into the true Blood Itself of the Lord, Which as He hung upon the Cross, was poured out for the life of the world" (Decree XVII).
