Paul recounts the institution of the Lord's supper.
Paul, First Epistle to the Corinthians (11:23-26), Codex Sinaticus
εγω γαρ παρελαβο απο του κυ ο και πα ρεδωκα ϋμιν οτι ο κϲ ιϲ εν τη νυκτι η παρεδιδετο ελαβεν αρτον και ευχαριϲτηϲαϲ ε κλαϲεν και ειπε τουτο μου εϲτιν το ϲωμα το ϋπερ ϋμων ┬ τουτο ποι ειται ειϲ την ε μην αναμνηϲι ωϲαυτωϲ και το ποτηριον μετα το διπνηϲαι λεγω τουτο το ποτηρι ον η καινη δια θηκη εϲτιν εν τω εμω αιματι τουτο ποιειτε ο ϲακιϲ εαν πινη τε ειϲ την εμην αναμνηϲιν οϲακιϲ γαρ εαν ε ϲθιητε τον αρτο τουτο και το πο τηριον ┬ πινητε τον θανατον του κυ καταγγελλετε αχρι ου ┬ ελθη ωϲτε οϲ αν εϲθιη τον αρτον η πινη το ποτηριον του κυ αναξιωϲ του κυ ενοχοϲ εϲτε του ϲωματοϲ και του αιματοϲ του κυ 23 For I received from the Lord that which I also delivered to you, that the Lord Jesus, on the night in which he was delivered up, took bread,
24 and after giving thanks he broke and said: This is my body which is for you; this do in remembrance of me.
25 In like manner also the cup, after he had supped, saying: This cup is the new covenant in my blood: this do, as often as you drink it, in remembrance of me.
26 For as often as you eat this bread and drink this cup, the death of the Lord you announce, till he come.
27 So then whoever shall eat the bread or drink the cup of the Lord in an unworthy manner, shall be guilty of the body and of the blood of the Lord.
