The Words of Institution (also called the Words of Consecration) are words echoing those of Jesus himself at his Last Supper that, when consecrating bread and wine, Christian Eucharistic liturgies include in a narrative of that event. The Roman canon utilizes the following form:

Take this, all of you, and eat of it:

for this is my body which will be given up for you.

Take this, all of you, and drink from it:

for this is the chalice of my blood,

the blood of the new and eternal covenant.

which will be poured out for you and for many

for the forgiveness of sins.

Do this in memory of me.
