No, the “remembrance” part comes from the Greek “anamnesis” which means “to make present”. It is not about “remembering” as in a mental image of the past even which we recal today. We call on God to remembrance of the covenant He made with us. When God “remembers”, God acts.
There’s no either/or. It is both.
ConstantineTG’s points are extremely important.
In Jewish culture and religion, from the time before Abraham, every covenant was sealed with a sacrifice and a shared meal. Those were the signs of the covenant.
The new and everlasting covenant between God and man is no different. God chose to sacrifice of himself in the person of Jesus and a to share a meal between the Apostles and himself in the person of Jesus. The Mass makes
both the sacrifice and the shared meal present to us, and through these we enter into the covenant with God.
The passover meal was every Jew’s ***personal ***participation in the Exodus.
And on that day you will explain to your son, ‘This is because of what the LORD did for me when I came out of Egypt.’ (Exodus 13:8)
On Passover night, every Jewish father was to explain to his children that the Passover is because of what God did for him personally, in leading him out of Egypt. The Mass is no different, and through the “Rememberance” of that meal - as ConstantineTG put it perfectly - God acts, we enter into the covenant, and Christ’s work is applied to us personally here and now.
The convenant requires both the shared meal and the sacrifice. There is no either/or. There is only the covenant, and the Mass makes both the last supper and Christ’s sacrifice of himself on the Cross present for us. It is our personal participation in the events of that day.
