It is the true body and blood of our Lord Jesus Christ under the bread and wine, instituted by Christ Himself for us Christians to eat and to drink.

The Holy Evangelists Matthew, Mark, Luke, and St. Paul write: Our Lord Jesus Christ no the night He was betrayed, took bread, and when he had given thanks, He broke it and gave it to the disciples and said, "Take, eat; this is My body, which is given to you. This do in rememberance of Me." In the same way also He took the cup after supper, and when He had given thanks, He gave it to them, saying, "Drink of it all of you; this cup is the New Testament in My blood, which is shed for you for the forgiveness of sins. This do, as often as you drink it, in rememberance of Me."
