|What is the Sacrament of the Lord’s Supper? It is the true body and blood of our Lord Jesus Christ under the bread and wine, for us Christians to eat and to drink, instituted by Christ Himself.|
Where is this written? The holy Evangelists Matthew, Mark, Luke and St. Paul (the Apostle) write thus: Our Lord Jesus Christ, the same night in which He was betrayed, took bread: and when He had given thanks, He brake it and gave it to His disciples, saying: Take, eat; this is My body, which is given for you. This do in remembrance of Me. After the same manner also He took the cup when He had supped, and when He had given thanks, He gave it to them, saying: Drink ye all of it: this cup is the new testament in My blood, which is shed for you for the remission of sins. This do, as oft as ye drink it, in remembrance of Me.
The Sacrament of the Lord’s Supper was instituted by our Lord and Savior Jesus Christ, who has all power, who knows all things, and who is able to give us that which He promises. The words with which Christ instituted this Sacrament are called the words of institution.
Ps. 33:4: For this Word of the Lord is right: and all His works are done in truth.
Eph. 3:20-21: Now unto Him that is able to do exceeding abundantly above all that we ask or think, according to the power that worketh in us, unto Him be glory in the Church by Christ Jesus throughout all ages, world without end.
