Except for the resurrection on Easter, Holy Thursday is possibly one of the most important, complex, and profound days of celebration in the Catholic Church. Holy Thursday celebrates the institution of the Eucharist as the true body and blood of Jesus Christ and the institution of the sacrament of the priesthood.

During the Last Supper, Jesus offers himself as the Passover sacrifice, the sacrificial lamb, and teaches that every ordained priest is to follow the same sacrifice in the exact same way. Christ also bids farewell to his followers and prophesizes that one of them will betray him and hand him over to the Roman soldiers.
