The Most Holy Eucharist did not develop from Jewish tradition, it was given to us, whole and entire by Our Blessed Savior, Jesus Christ, at the Last Supper. However, it was prefigured in the Old Testament in many ways: for instance, the tree of Life in the garden of Eden which gives eternal life prefigures the Eucharist. The Passover lamb prefigures the Eucharist. The bread and wine offered by the priest, Melchizedek (King of Salem) prefigures the Eucharist. The blood of the covenant (Exodus 24:8) The manna in the desert prefigures the Eucharist. The showbread or Bread of the Presence, which was to be before the Arc of the Covenant always, prefigures the Eucharist.
