Question 120

How is Jesus’ offering expressed at the Last Supper?

Answer

At the Last Supper with his apostles on the eve of his passion Jesus anticipated, that is, both symbolized his free self-offering and made it really present: “This is my Body which is given for you” (Luke 22:19), “This is my Blood which is poured out...” (Matthew 26:28) Thus he both instituted the Eucharist as the “memorial” (1 Corinthians 11:25) of his sacrifice and instituted his apostles as priests of the new covenant.
