I could immediately see the parallels to the Mass. First, the prayers of the blessing of the wine and unleavened bread at the Passover are almost word for word what is used at Mass. At Mass, during the Eucharistic Prayer, we remember those who are no longer with us, and we pray that when we die, we'll see God in Heaven; the New Jerusalem.
The Jews used the blood of the Lamb, and it's flesh to protect their families from the Angel of Death. We are washed clean of our sins and protected by the Blood of the Lamb, Jesus's sacrifice on the Cross, and by eating his flesh, as He commanded, we too are strengthened in our journey to that New Jerusalem.
Bumping this wonderful talk by Scott Hahn. One that all Catholics need to read!
Especially the part about Adoration!
