If the reader will take up his Bible and read carefully the 6th chapter of the Gospel according to St. John; the 26th chapter, 26th, 27th, and 28th verses of St. Matthew; the 14th chapter, 22d verse of St. Mark; the First Epistle of St. Paul to the Corinthians, 10th chapter, 16th verse, as well as other portions of the New Testament, he will certainly see that the Catholic teaching and practice concerning the Real Presence of Jesus Christ in the Blessed Sacrament are founded on Scripture. In this 6th chapter of St. John, we learn that before instituting the Blessed Sacrament Our Saviour wished to announce or promise it to His disciples in order to prepare them for it. He first gave them a figure of the Blessed Sacrament in the multiplication of the five loaves of bread by which He fed five thousand persons. After this miracle He told them that He would give them bread superior to that which they had eaten, and that this bread was His own flesh and blood. "The bread that I will give is My flesh, for the life of the world." It is almost impossible to understand these words of Our Lord in any other than a literal sense. He was so understood by those who heard Him. "How can this man give us his flesh to eat?" they said, and many withdrew from Him. It is but reasonable to believe that if He did not wish to be understood in a literal sense He would have told His hearers so, rather than have them leave Him. This promise of a doctrine so difficult to understand was fulfilled at the Last Supper. Then Jesus took bread, and blessed, and broke, and gave to His disciples, and said: "Take ye and eat. This is My body." And taking the chalice He gave thanks; and gave to them, saying: "Drink ye all of this. For this is My blood of the new testament which shall be shed for many for the remission of sins." "Do this for a commemoration of Me." These are substantially the words of SS. Matthew, Mark, Luke, and of the apostle Paul. In the 10th chapter of the First Epistle to the Corinthians, St. Paul says: "The chalice of benediction which we bless, is it not the communion of the blood of Christ? And the bread which we break, is it not the partaking of the body of the Lord?" Any one of these texts abundantly proves the Catholic doctrine of the Real Presence, and shows the reasonableness of the Catholic practice regarding the Blessed Sacrament. Reflect upon them. Reflect especially upon the words of Christ, "This is My body." Think what an insult it is to the divinity and veracity of Christ to doubt His word, because you can not understand how what appears to be bread is in reality His own body and blood.
