1 Corinthians 11:23

(18) For I have received of the Lord that which also I delivered unto you, That the Lord Jesus the [same] night in which he was betrayed took bread:

(18) We must take a true form of keeping the Lord's supper, out of the institution of it, the parts of which are these: touching the pastors, to show forth the Lord's death by preaching his word, to bless the bread and the wine by calling upon the name of God, and together with prayers to declare the institution of it, and finally to deliver the bread broken to be eaten, and the cup received to be drunk with thanksgiving. And touching the flock, that every man examine himself, that is to say, to prove both his knowledge, and also faith, and repentance: to show forth the Lord's death, that is, in true faith to yield to his word and institution: and last of all, to take the bread from the minister's hand, and to eat it and to drink the wine, and give God thanks. This was Paul's and the apostles' manner of ministering.
