Passover is a Jewish ceremony, totally foreign to the rituals of the Catholic Eucharist.
At any rate, if Catholics follow a faithful Jew, they should be celebrating Passover ... period ... and be following all the Jewish rituals and beliefs.
That would be THE path to follow.
Instead Catholic theologians lead the flock AWAY from Judaism.
And THAT is the truth of THAT "MATTER."
So what is the Jewish Passover "ceremony"? In short the sacrifice of a lamb, to save individuals from death.
So what is the central part of the Catholic Mass/Eucharist?
Everyone says three times, "Lamb of God, you take away the sins of the world..." As the perfect Sacrifice, since it came from God.
And that's the Truth.
