You might be confusing different sacrafices from the levitical laws. The Passover is one of the meals celebrated by all Jewish families, which partook of the blessing of bread ,blessing of the 4 cups of wine, with the consuming of a lamb. This was a seder meal.
The other sacrafices that only the priests consumed were of the sacred kind, when only the Priest and his immediate family members could only consume.
They’re are others, what I like to mention is these all sacraficial meals Jesus fulfilled once and for all, through his passion as the lamb of God who takes away the sins of the world, in the unleavend bread as his body, and oblation of wine which became his blood. By his own words of consecration.
The fact to take note is that in the passover (Seder) meal, Jesus saves humanity by not allowing us to die a death in our sins and not allow death to overtake us in eternity, just as it fulfills the OT passover from the angel of death to passover all the first born and animals included.
The celebration of the High priest sacrafice for atonement meal was consumed by God from heaven in fire, then what was left was for the High priest and his family.
This is a typo of Jesus and the sons and daughters of the living God, that consume the lamb sacrafice in the sacred place, thus this is fulfilled also in the Lamb sacrafice and must be a perpetual sacrafice, just as Jesus stated to do in “remembrance of me” (make me present).
The perpetual of the law is fulfilled in Jesus. This takes place only in the Mass, because it is here where the high priest Jesus and his brothers and sisters partake of the hidden manna in the secret Place, in the Mass, where heaven and earth meet. Protestant 101 makes a good point, but Jesus fulfills all the sacrafices, and liturgical laws pertaining to the bread and wine. He fulfills them in the true presence of the Eucharist celebration.
It must be a true presence as Jesus states his body and blood we must eat and drink in order to have life. For without the shedding of blood their is no salvation. God will not accept a sacrafice like that of cain a symbolic sacrafice, only the one that speaks from the earth more eloguently as Abels sacrafice a real lamb and real blood. Anything else will cause the one offering this unholy sacrafice wrath and curses, as ST. Paul states in 1Corinthians 11, their is much more to address on these sacrafices that Jesus fulfilled that have not been mentioned here.
