Why do Catholics believe in the real presence and others do not? It is as simple as this…If you believe in the real presence you will be Catholic. I came to the Church because of this initially and will stay because of this but not only because of this. I invite others to consider the words in John 6 carefully…and personally…without listening to what others may say. The Eucharist calls…all one needs to do is heed the call…everything else will fall into place.
You ask, Do you not believe in the real presence of Christ in the Eucharist? Some may not know the meaning of the term Eucharist. It is “thanksgiving.” Oh yes, dear friends, every instructed Christian believes in the real presence in the Eucharist, but He does not believe that the bread ceases to be anything but bread and he does not believe that the wine ceases to be anything but wine. He does not believe in a strange, mysterious transformation of cereal bread and of wine into the body, blood, soul and divinity of Jesus Christ. But he believes this: “Where two or three are gathered together in My name (as Jesus said) there am I in the midst.” Some of the sweetest moments of my life have been spent at the Table of the Lord, communing with the Blessed One who of old said, “Do this in remembrance of Me,” and faith’s eye could discern Him there standing in the midst, showing His wounds and spreading His hands.
I heard it said that"Catholics believe in the real presence of Christ in the Eucharist; Protestants believe in the real absence." But that is false. Protestants do not believe that the bread and wine undergo any mystic change, but they do believe that as you eat and drink in remembrance of Christ, Christ is present in His sweet and wonderful way, manifesting Himself to the hearts of His beloved people so that by faith they are enabled to feed upon Him. We feed upon Him in remembrance. We look back and think of the sorrows He bore. We contemplate His cross and bitter passion, and as we do, we eat of His flesh and drink of His blood, and as we feast on Christ we find our love for those things for which Christ died upon the cross becoming less, and our love for those blessed things into which He would lead us through the new and living way, through the veil into the holiest, becoming greater, for we become like that upon which we feed.
Now turn to the Gospel of Mark and get his account of the same Supper.
“And as they did eat, Jesus took bread, and blessed, and brake it, and gave to them, and said, Take, eat: this is my body. And He took the cup, and when He had given thanks, He gave it to them: and they all drank of it. And He said unto them, This is my blood of the new testament, which is shed for many. Verily I say unto you, I will drink no more of the fruit of the vine, until that day when I drink it new in the kingdom of God. And when they had sung an hymn, they went out into the mount of Olives.”
“And as they did eat.” I would draw your attention to that. Every Roman Catholic is instructed to take the Sacrament of the Mass fasting. Have you read that after “they did eat, Jesus took bread.” They were just concluding the Passover meal. And “Jesus took bread
Now I turn you to the account given by Luke,
“And He took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of Me. Likewise also the cup after supper, saying, This cup is the new testament in my blood, which is shed for you.”
‘As often as ye eat this bread and drink this cup ye do show the Lord’s death till He come.’ If you don’t believe He is coming again you’d better cut that out. It is a witness that the Christ who died is coming again. He says, While you are waiting for Me, do this in remembrance of Me."
“Wherefore whosoever shall eat this bread, and drink this cup of the Lord, unworthily, shah be guilty of the body and blood of the Lord.”
Then in the 10th chapter of the same Epistle we read in verse 16:
“The cup of blessing which we bless, is it not the communion of the blood of Christ? The bread which we break, is it not the communion of the body of Christ?” Verse 21: “Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord’s table, and of the table of devils.”
The Apostle John does not give us any account of the institution of the Lord’s Supper, but after Christ’s ascension and after the conversion of Saul of Tarsus when he became the Apostle Paul, a special revelation was given to him, and in the 11th chapter of 1st Corinthians we get the full account of it. Read from verse 20:
“When ye come together therefore into one place, this is not to eat the Lord’s supper. For in eating every one taketh before other his own supper: and one is hungry, and another is drunken. What! have ye not houses to eat and drink in? or despise ye the church of God, and shame them that have not? What shall I say to you? Shall I praise you in this? I praise you not. For I have received of the Lord (the risen, ascended, glorified Lord) that which also I delivered unto yen, That the Lord Jesus the same night in which He was betrayed (the night in which He was to know experimentally the untrustworthiness of the human heart) 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. For as often as ye eat this bread, and drink this cup, ye do show the Lord’s death till He come."
Observe how this feast links together the two great facts of Christianity, the death of Christ and His second coming. The Lord’s Supper is taken in remembrance of One who died, but as we take it we look forward and wait for His coming again.
