In this fourth part of the series, Father Richard Gilsdorf speaks of the promise Our Lord gave to his people of the Holy Eucharist. This manna of the Old Testament is now renewed in Christ. Furthermore, Christ's multiplication of the loaves is a prefiguring of what is one day to come in his most holy Eucharist. This lecture clearly lays out the sings in the Old and New Testaments that God has given his people to understand the promise of the Eucharist.
