There is an insight in the Mishnah (the rabbinic commentaries on the Torah from the centuries around and after Jesus' time) that it was not just the "Moses Generation" that trekked out of Egypt and across the Red Sea, but in truth every Israelite after them did so as well. The passage reads:
The tanna of the mishna further states: In each and every generation a person must view himself as though he personally left Egypt, as it is stated: “And you shall tell your son on that day, saying: It is because of this which the Lord did for me when I came forth out of Egypt” (Exodus 13:8). In every generation, each person must say: “This which the Lord did for me,” and not: “This which the Lord did for my forefathers.” The mishna continues with the text of the Haggadah. Therefore we are obligated to thank, praise, glorify, extol, exalt, honor, bless, revere, and laud the One who performed for our forefathers and for us all these miracles: He took us out from slavery to freedom, from sorrow to joy, from mourning to a Festival, from darkness to a great light, and from enslavement to redemption. And we will say before Him: Halleluya.
This is the rabbinic line of thought that animates St. Paul in today's 2nd Reading, and that he and his close associate, St. Luke, will develop further in the Christian idea of an anamnēsis, which translates the Hebrew zikkaron— a lasting remembrance, an eternal memorial.
