Asked in Eucharist (Communion)
What is the difference between the Last Supper and the Holy Eucharist?
There is no difference: the Last Supper was the first celebration of the Holy Eucharist. The Gospels are quite explicit in Christ's intention to institute and perform this sacrament that night. The Last Supper, however, was the last valid celebration of the Old Covenant Pasch, after which Christ instituted the new.
