The Greek word used for “rememberence” is actually anamnesis, a word that has no real translation in English. It basically means to “live it again”, or to connect to an eternal event/thing. It definately doesn’t mean to simply remember; the closest we can come is “re-present”, as in “make present again”. Memory is a function very different from anamnesis.
In other words, when the Eucharist is confected at the Mass or Divine Liturgy it’s not a comemoration of the Last Supper, and in fact it’s not even really a new event at all, but rather our participation in the Eucharist that Christ made with his disciples. It’s not so much happening again as it is us going back to be present at that event again, hence “re-present”.
It’s a truly awesome and amazing gift from God, and the words used in the original language of Scripture absolutely attest to its reality. The Mass truly is the most incredible thing on Earth.
ANAMNESIS and Memorial Sacrifice
There is the statement of Jesus concerning anamnesis (Luke 22:19; 1 Cor 11:24) which clearly implies the Eucharist is to be a perpetual “memorial sacrifice” given the OT background of the language used:
***Touto poieite eis ton emen anamnesin ***translated "Do this in remembrance of Me"
Poiein(“DO”) has sacrificial overtones. In the Septuagint (LXX), the Greek version of the OT, there are about seventy sacrificial uses of poiein. One example: “*Now this is what you shall OFFER *[Gr poieseis] upon the ALTAR: two lambs a year old, day by day, continually” (see Exodus 29:38).
ANAMNESIS(“REMEMBRANCE”) also has sacrificial overtones. It occurs only eight times in the NT and the Greek OT. All but once (Wisdom 16:6) it is in a sacrificial context: “There is in these SACRIFICES a REMINDER [Gr anamnesis] of sin year after year” (Heb 10:3).
“And you shall put pure frankincense with each row, that it may go with the bread as a MEMORIAL portion [Gr anamnesis] to be OFFERED by fire to the Lord” (Lev 24:7).
“On the day of your gladness…you shall blow over your burnt OFFERINGS and over the SACRIFICES of your peace OFFERINGS; they shall serve you for REMEMBRANCE (Gr anamnesis) before your God” (Num 10:10).
Psalm 38 (39) is titled “A Psalm of David, for the MEMORIAL OFFERING” [Gr anamnesin]. Psalm 70 (71) is titled, “To the choir-master. A Psalm of David, for the MEMORIAL OFFERING” [Gr anamnesin].
In these cases the term ANAMNESIS can be translated as “memorial portion,” “memorial offering,” or “memorial sacrifice.”
Thus in the remaining two occurances of ANAMNESIS (Luke 22:19; 1 Cor 11:24), Christ’s words “DO THIS*** in REMEMBRANCE* of Me**,” can be translated as “OFFER THIS for my memorial SACRIFICE.” Given the sacrificial character of the Eucharist, there is little doubt this translation is appropriate. To tell someone, “offer this for my memorial sacrifice” is to direct him to fulfill a priestly function (see Heb 5:1; 8:3).
The Catholic Church has correctly regarded Christ’s words as the institution of the apostles’ priesthood and as the basis for all future priests who offer the Eucharistic sacrifice
