A Love So Complete

Jesus didn't say to memorialize his death. He said we were to participate in anamnesis. We do that by bringing his sacrifice into our present and participating in it. Similarly, we do anamnesis with the resurrection every Sunday. The early Christians (the ones who knew Jesus while he was on earth) began this tradition of celebrating both the resurrection and the Meal every week, to participate weekly in the anamnesis. And, surely, there could be no truer Christians than these!

the passover was a yearly thing , and Jesus memorial is to be a yearly thing.
Certain features of the Passover observance were fulfilled by Jesus.
One fulfillment lies in the fact that the blood on the houses in Egypt delivered the firstborn from destruction at the hands of the destroying angel. Paul speaks of anointed Christians as the congregation of the firstborn (Heb 12:23), and of Christ as their deliverer through his blood. (1Th 1:10; Eph 1:7) No bones were to be broken in the Passover lamb. It had been prophesied that none of Jesus’ bones would be broken, and this was fulfilled at his death. (Ps 34:20; Joh 19:36) Thus the Passover kept by the Jews for centuries was one of those things in which the Law provided a shadow of the things to come and pointed to Jesus Christ, "the Lamb of God."—Heb 10:1; Joh 1:29.
Many churches claim that they hold this observance in conjunction with all their other feasts, but most commemorate it differently from the way Jesus commanded. Perhaps the most noteworthy difference is the frequency of the celebration. Some churches celebrate it monthly, weekly, even daily. Is this what Jesus intended when he told his followers: "Keep doing this in remembrance of me"? The New English Bible says: "Do this as a memorial of me." (1 Corinthians 11:24, 25) How often is a memorial or an anniversary observed? Usually, just once a year.

Which would be fine, if "memorial" were true to the original meaning of anamnesis.

However, as I've shown, anamnesis is more a participation in, rather than a reminiscence of, an event.

Easter only comes once a year. An annual event. Christmas only comes once a year. An annual event. Just like Passover.

However, the compelling factor here is the praxis of the early Christians, which indicated a weekly liturgy of breaking bread.

The Jewish custom of keeping Passover had nothing whatsoever to do with Jesus. That is a meaning applied only later, by his followers.
