Read Mark 14:25, where Jesus said “I tell you the truth, I will not drink again of the fruit of the vine until that day when I drink it anew in the kingdom of God.” Why did He call it “fruit of the vine” if it was His blood?
Because in John 15:1,5 Jesus said: “I am the vine.”
Also, 1 Cor. 11:27-29 - in these verses, Paul says that eating or drinking in an unworthy manner is the equivalent of profaning (literally, murdering) the Body and Blood of the Lord. If this is just a symbol, we cannot be guilty of actually profaning (murdering) it. We cannot murder a symbol. Either Paul, the divinely inspired apostle of God, is imposing an unjust penalty, or the Eucharist is the actual Body and Blood of Christ.
How about 1 Cor. 10:16? Paul asks the question, “the cup of blessing and the bread of which we partake, is it not an actual participation in Christ’s body and blood?” Is Paul really asking because He, the divinely inspired writer, does not understand? No, of course not. Paul’s questions are obviously rhetorical. This IS the actual body and blood. Further, the Greek word “koinonia” describes an actual, not symbolic participation in the body and blood. John 6:51-52- then Jesus says that the bread He is referring to is His flesh. The Jews take Him literally and immediately question such a teaching. How can this man give us His flesh to eat?
John 6:53 - 58 - Jesus does not correct their literal interpretation. Instead, Jesus eliminates any metaphorical interpretations by swearing an oath and being even more literal about eating His flesh. In fact, Jesus says four times we must eat His flesh and drink His blood. Catholics thus believe that Jesus makes present His body and blood in the sacrifice of the Mass. Protestants, if they are not going to become Catholic, can only argue that Jesus was somehow speaking symbolically.
John 6:23-53 - however, a symbolic interpretation is not plausible. Throughout these verses, the Greek text uses the word “phago” nine times. “Phago” literally means “to eat” or “physically consume.” Like the Protestants of our day, the disciples take issue with Jesus’ literal usage of “eat.” So Jesus does what?
John 6:54, 56, 57, 58 - He uses an even more literal verb, translated as “trogo,” which means to gnaw or chew or crunch. He increases the literalness and drives his message home. Jesus will literally give us His flesh and blood to eat. The word “trogo” is only used two other times in the New Testament (in Matt. 24:38 and John 13:18) and it always means to literally gnaw or chew meat. While “phago” might also have a spiritual application, “trogo” is never used metaphorically in Greek. So Protestants cannot find one verse in Scripture where “trogo” is used symbolically, and yet this must be their argument if they are going to deny the Catholic understanding of Jesus’ words. Moreover, the Jews already knew Jesus was speaking literally even before Jesus used the word “trogo” when they said “How can this man give us His flesh to eat?” (John 6:52).
John 6:55 - to clarify further, Jesus says “For My Flesh is food indeed, and My Blood is drink indeed.” This phrase can only be understood as being responsive to those who do not believe that Jesus’ flesh is food indeed, and His blood is drink indeed. Further, Jesus uses the word which is translated as “sarx.” “Sarx” means flesh (not “soma” which means body). See, for example, John 1:13,14; 3:6; 8:15; 17:2; Matt. 16:17; 19:5; 24:22; 26:41; Mark 10:8; 13:20; 14:38; and Luke 3:6; 24:39 which provides other examples in Scripture where “sarx” means flesh. It is always literal.
John 6:55 - further, the phrases “real” food and “real” drink use the word “alethes.” “Alethes” means “really” or “truly,” and would only be used if there were doubts concerning the reality of Jesus’ flesh and blood as being food and drink. Thus, Jesus is emphasizing the miracle of His body and blood being actual food and drink.
John 6:60 - as are many anti-Catholics today, Jesus’ disciples are scandalized by these words. They even ask, “Who can ‘listen’ to it (much less understand it)?” To the unillumined mind, it seems grotesque.
John 6:61-63 - Jesus acknowledges their disgust. Jesus’ use of the phrase “the spirit gives life” means the disciples need supernatural faith, not logic, to understand His words.
John 3:6 - Jesus often used the comparison of “spirit versus flesh” to teach about the necessity of possessing supernatural faith versus a natural understanding. In Mark 14:38 Jesus also uses the “spirit/flesh” comparison. The spirit is willing but the flesh is weak. We must go beyond the natural to understand the supernatural. In 1 Cor. 2:14,3:3; Rom 8:5; and Gal. 5:17, Paul also uses the “spirit/flesh” comparison to teach that unspiritual people are not receiving the gift of faith. They are still “in the flesh.”
John 6:63 - Protestants often argue that Jesus’ use of the phrase “the spirit gives life” shows that Jesus was only speaking symbolically. However, Protestants must explain why there is not one place in Scripture where “spirit” means “symbolic.” As we have seen, the use of “spirit” relates to supernatural faith. What words are spirit and life? The words that we must eat Jesus’ flesh and drink His blood, or we have no life in us.
John 6:66-67 - many disciples leave Jesus, rejecting this literal interpretation that we must eat His flesh and drink His blood. At this point, these disciples really thought Jesus had lost His mind. If they were wrong about the literal interpretation, why wouldn’t Jesus, the Great Teacher, have corrected them? Why didn’t Jesus say, “Hey, come back here, I was only speaking symbolically!”? Because they understood correctly.
