The Institution of the Eucharist

1 Corinthians 11 

23 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 Ego enim accepi a Domino quod et tradidi vobis, quoniam Dominus Jesus in qua nocte tradebatur, accepit panem,

24 And giving thanks, broke, and said: Take ye, and eat: this is my body, which shall be delivered for you: this do for the commemoration of me. et gratias agens fregit, et dixit : Accipite, et manducate : hoc est corpus meum, quod pro vobis tradetur : hoc facite in meam commemorationem.

25 In like manner also the chalice, after he had supped, saying: This chalice is the new testament in my blood: this do ye, as often as you shall drink, for the commemoration of me. Similiter et calicem, postquam coenavit, dicens : Hic calix novum testamentum est in meo sanguine : hoc facite quotiescumque bibetis, in meam commemorationem.

26 For as often as you shall eat this bread, and drink the chalice, you shall shew the death of the Lord, until he come. Quotiescumque enim manducabitis panem hunc, et calicem bibetis, mortem Domini annuntiabitis donec veniat.
