Let's look at the verbatim words of Scripture:
Matthew 26:26-29
"Now as they were eating, Jesus took bread and blessed and broke it and gave it to the disciples and said, 'Take, eat, this is my body.' And he took the cup and when he had given thanks he gave it to them saying, 'Drink of it all of you, for this is my blood of the new covenant, which is poured out for many for the forgiveness of sins. I will you, I will not drink again of this fruit of the vine again until I drink it with you in my father's kingdom." (see also Mark 14:22-24, Luke 22:19-20)
1 Corinthians 11:23-29
The Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it and said, 'This is my body which is for you. Do this in remembrance of me.' In the same way also the cup saying, 'This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.' For as often as you eat this bread and drink this cup, you proclaim the Lord's death until he comes. Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty of profaning the body and blood of the Lord. Let a man examine himself and so eat of the bread and drink of the cup. For anyone who eats or drinks without discerning the body, eats and drinks judgment upon himself."
There are three major "schools" on these in the West...
Real Presence: This view accepts these verses "as is" - with nothing added, deleted, substituted, denied or "explained away" - and with no pagan philosophies or rejected prescience theories imposed or dogmatiozed. "Is" = is, every time (Real, present, exists). "Body" = body, every time. "Blood" = blood, every time. That's it. That's all. Body and blood IS... ARE..... thus present, real, there and thus received. While Real Presence technically doesn't mention the bread and wine or deal with that, it doesn't IN ANY SENSE deny such "exists" either - it's just insignificant. This view simply accepts all the words - as is, with no attempt to change some or ignore some or to impose some scientific concept or to "explain" away anything or theorize about anything. It understands all this as "MYSTERY." It says only what Jesus and Paul says; questions are welcomed just left unanswered (dogmatically, anyway). THAT it is true is fully embraced; HOW it is true is left alone. This view is currently embraced by Lutherans, as well as some Anglicans and Methodist. Orthodox hold to a variation of this, insisting that bread and wine do not exist in a FULL sense, but otherwise it's the same.
Transubstantiation: First expressed in 1134, first officially mentioned in 1214 and made dogma exclusively in the individual RC Denomination in 1551, it holds that the word "is" should be replaced by the words "CHANGED and/or CONVERTED and/or TRANSFORMED from one reality to a completely foreign different reality." It then holds that this CHANGE happens via an alchemic transubstantiation (from which comes the name the RCC gave for this view). This, however, causes a problem with the texts which mentions bread and wine AFTER the Consecration (in First Corinthians, MORE than before) in EXACTLY the same way as such is mentioned BEFORE the Consecration. This view thus replaces those words, too. Instead, this view holds that "bread" and "wine" be replaced with, an Aristotelian ACCIDENT or appearance or species of bread and wine but not really bread and wine at all - just the 'empty shell' of what is left over after the alchemic transubstantiation CHANGE. It denies that bread and wine are present in any full, literal, real sense (in spite of what the Bible says). Two pagan ideas are imposed: Transubstantiation and Accidents. Several words are deleted: "Is" "bread" and "wine" (the later two only after the Consecration). This view is the official Eucharistic dogma of the Roman Catholic Church since 1551. No other church holds to it.
Figurative/Symbolic/Memorial: This view holds that the word "is" indicates a figure of speech and that there is a metaphor. It insists and the bread and wine are here made SYMBOLS or FIGURES or memorials of His Body and Blood. Christ is not "present" at all (in any sense other than He always is present), but the bread and wine are now symbols of Christ and His sacrifice. It is often compared to the Old Covenant Passover Meal - a memorial to REMIND us of things. The terms "body" and "blood" so stressed by Jesus and Paul are simply stripped of their USUAL meaning and said to be "symbols" or "figures" or "memorials" of them. "Is" doesn't mean "is" but "a figure of." This view is typically associated with Zwingli. This view is now popular among modern American "Evangelicals" and frequently among modern Reformed/Calvinists.
One might summerize the 3 common views this way:
LUTHERANS: Is.... Body..... Blood..... bread..... wine....... All are true, all are affirmed. It's mystery.
ROMAN CATHOLIC: Body.... Blood..... THEY are true and affirmed, but "is" doesn't mean that and the bread and wine actually aren't, they are Aristotelian Accidents instead. It's an alchemic Transubstatiation.
EVANGELICALS: Bread.... Wine.... THEY are true and affirmed, but "is" doesn't mean that and the Body and Blood actually aren't, they are symbols instead. It's metaphor.
I hope that helps.
