Consubstantiation
The Lutheran view is called consubstantiation (or the real-presence or mystical-presence view). After consecration, the bread remains bread and the wine remains wine; however, the real, physical body and blood of Jesus are, as the Lutheran confessions put it, present “in, with, and under” the bread and wine. The bread and wine are not the body and blood of Jesus, but they do contain his body and blood.
Transubstantiation
As to the meaning of the Lord’s Supper, the Roman Catholic view is called transubstantiation: During the Mass, when the priest consecrates the bread, it actually becomes Christ’s physical body, and when he consecrates the wine, it actually becomes Christ’s physical blood.

Anglican Thomas Chalmers essentially said Christ is in heaven until the day of His return. So He cannot be in the bread and cup. “Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began.” Acts 3:21 (KJV 1900)
Also, does it mean Christ did not come in the flesh if this is the human flesh he supposedly came in? John says whoever denies that Christ came in the flesh is an Antichrist.
It seems that if anyone should be able to interpret Christ’s difficult passages on the Eucharist, it should be Paul. “For I have received of the Lord that which also I delivered unto you, “that the Lord Jesus the same night in which he was betrayed took bread: And when he had given thanks, he brake it, and said, Take, eat: this is my body, which is broken for you: this do in remembrance of me. After the same manner also he took the cup, when he had supped, saying, this cup is the new testament in my blood: this do ye, as oft as ye drink it, in remembrance of me.” 1 Corinthians 11:23–25 (KJV 1900)
Notice He says “this is the New Testament in my blood”. It does not mean the wine changes into the New Testament, it represents the New Testament in his blood on the cross. Nor does it mean that His blood, instead of the New Testament, is present in the wine. A DNA test should not be necessary to prove either, but none are willing to prove what they say is true by using it.
Christ does not say what Transubstantiationists or Consubstantiationists say. He says the bread and cup are for remembrance sake. “This do in remembrance of me”.
Paul in scolding the gluttons from Corinth for abusing the communion service Said: “For as often as ye eat this bread, and drink this cup, ye do shew the Lord’s death till he come. Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shall be guilty of the body and blood of the Lord. But let a man examine himself, and so let him eat of that bread, and drink of that cup. For he that eateth and drinketh unworthily, eateth and drinketh damnation to himself, not discerning the Lord’s body.” 1 Corinthians 11:26–29 (KJV 1900) The NLT says: “For if you eat the bread or drink the cup without honoring the body of Christ, you are eating and drinking God’s judgment upon yourself.” 1 Corinthians 11:29 (NLT)
