In other words, Roman Catholics believe that transubstantiation is the 'change' that occurs in the 'whole substance' of the bread and wine set apart for the Eucharistic mystery. This is a change that takes place at the words of institution or consecration (i.e. 'This is My Body,' etc.). There's some Scholastic language here, of course, but that's the basic gist. In the Orthodox tradition, you will find it taught variously that this change takes place anywhere between the Proskomedia (the Liturgy of Preparation)—which is now a separate service prior to both Orthros and the Divine Liturgy on a typical Sunday, though traditionally it is done during Orthros—and the Epiklesis ('calling down'), or invocation of the Holy Spirit 'upon us and upon these gifts here set forth' (as in Chrysostom's liturgy). As such, the gifts should be treated with reverence throughout the entirety of the service. We don't know the exact time in which the change takes place, and this is left to mystery. As Orthodox Christians, we must be careful to balance and nuance our claims, especially with regards to the Latins or 'the West.' The last thing we want to do is oversimplify matters to the extent of seeming deceptive or—perhaps worse—misinformed. After all, this is typically what gets thrown our way from those unfamiliar with Orthodoxy (beyond literature), often justly putting us on the 'defensive' (an important distinction from 'triumphalism') in response to such misrepresentations.
How the bread and wine of the Eucharist become the Body and Blood of Christ after a special, sacramental and heavenly manner and still remain bread and wine, and how our Lord is really present (real as being the presence of a reality), is a mystery which no human mind can satisfactorily explain. It is a mystery of the same order as how the divine Logos could take upon himself human nature and become man without ceasing to be divine. It is a mystery of the Faith, and we were never promised that all the mysteries would be solved in this life. The plain man (and some not so plain) is wisest in sticking to the oft-quoted lines ascribed to Queen Elizabeth, but probably written by John Donne: 'Christ was the Word that spake it; He took the bread and brake it; And what the Word did make it, That I believe and take it.' The mysteries of the Eucharist are three: The mystery of identification, the mystery of conversion, the mystery of presence. The first and primary mystery is that of identification; the other two are inferences from it. The ancient Fathers were free from Eucharistic controversy because they took their stand on the first and primary mystery—that of identification—and accepted our Lord's words, 'This is my Body', 'This is my Blood', as the pledge of the blessings which this Sacrament conveys. We have since the early Middle Ages lost their peace because we have insisted on trying to explain unexplainable mysteries. But let it be repeated, Anglo-Catholics are not committed to the doctrine of Transubstantiation; they are committed to the doctrine of the Real Presence.
As Confessional Lutherans we believe in baptismal regeneration, the real presence of Christ's body and blood in the Lord's Supper, and infant baptism.
Although some Lutherans have used the term 'consbstantiation' [sic] and it might possibly be understood correctly (e.g., the bread & wine, body & blood coexist with each other in the Lord's Supper), most Lutherans reject the term because of the false connotation it contains...either that the body and blood, bread and wine come together to form one substance in the Lord's Supper or that the body and blood are present in a natural manner like the bread and the wine. Lutherans believe that the bread and the wine are present in a natural manner in the Lord's Supper and Christ's true body and blood are present in an illocal, supernatural manner.
We reject transubstantiation because the Bible teaches that the bread and the wine are still present in the Lord's Supper (1 Corinthians 10:16, 1 Corinthians 11:27–28). We do not worship the elements because Jesus commands us to eat and to drink the bread and the wine. He does not command us to worship them.

{{cite web}}: External link in |quote=The Greek term corresponding to transubstation is metousiosis, which, however is not bound up with the scholastic theory of substance and accidents. It was accepted by the Synod of Bethlehem, 1672, during the reaction against the Calvinizing movement of the Patriarch Cyril Lucaris, but it was never accepted formally by the Russian Church, and it is not a dogma of the Orthodox Communion.
Advocates of the pneumatic presence might point to the efficacy of the Holy Spirit as somehow applying the virtues or power of the body of Christ to the faithful. Some within this camp might emphasize an instrumental manner by which the Holy Spirit uses the elements as a means of communicating the efficacy of the body of Christ. This view might be best associated with John Calvin. Others within this camp focus on a parallelism by which as the mouth feeds on the consecrated elements so does the heart feed on the body of Christ. This seems to be the emphasis of the Anglican divine Thomas Cranmer.
It is important to note at this point that there is major agreement among Roman Catholics, Lutherans, Anglicans, the Reformed, and the Particular Baptists that Christ is truly present in the Lord's Supper. They all go beyond the view of the Supper as a bare sign or memorial ... The debate among Catholics, Lutherans, and Reformed people is one that focuses on the mode of Christ's presence in the Lord's Supper. At the bottom, this debate is not so much sacramental as it is christological. [sic]
Rather, the substance of Christ's body and blood is joined to them (consubstantiation).
We believe the Scriptures teach that Christian baptism is the immersion in water of a believer, into the name of the Father, and Son, and Holy Ghost; to show forth in a solemn and beautiful emblem, our faith in the crucified, buried, and risen Savior, with its effect, in our death to sin and resurrection to a new life; that it is prerequisite ... to the Lord's Supper, in which the members of the church, by the sacred use of bread and wine, are to commemorate together the dying love of Christ; preceded always by solemn self-examination.
The Lord's Supper is a symbolic act of obedience whereby members ... memorialize the death of the Redeemer and anticipate His Second Coming.

Lutherans have always emphasized that Christ's true body and blood are really present 'in, with, and under' the bread and wine and that Christ's true body and blood are received by all who receive the elements, either to their blessing or to their condemnation…Lutherans emphasize that although the presence of Christ in the Sacrament is a supernatural presence, which is beyond our understanding and explanations, it is a real, substantial presence. Jesus simply says, 'This is my body. This is my blood,' and Lutherans confess this when they say, 'The bread and wine we receive are Christ's body and blood.' They also combine the words 'in and under' from the Catechism and the word 'with' from the Formula of Concord into the expression 'Christ's body and blood are received in, with, and under the bread and wine.'
