You may call it whatever you choose. It was Christ who said “remembrance”, the prayer of thanks and blessing (eucharist) came to be applied to whole later.
And Paul added that so long as the meal took place the death of Christ was proclaimed. (1 Cor. 11:26)
So call it what you wish but what is more descriptive and reflective of Christ’s command.
The Church chose Eucharist long ago. Along with remembrance there is also thanks in the scriptural reference: “For I received from the Lord what I also delivered to you, that the Lord Jesus on the night when he was betrayed took bread, and when he had given thanks, he broke it, and said, “This is my body which is for you. Do this in remembrance of me.”
Paul also wrote concerning the Real Presence:
“The cup of blessing which we bless, is it not a participation in the blood of Christ? The bread which we break, is it not a participation in the body of Christ?” …
“Therefore whoever eats the bread and drinks the cup of the Lord unworthily will have to answer for the body and blood of the Lord. . . . For any one who eats and drinks without discerning the body, eats and drinks judgment on himself”
The Real Presence, the Holy Eucharist, is Christian worship from the beginning of the Church, from Christ’s command “This is my body which is for you. Do this..”.
When we reduce this sacrament, remove its sacredness, we have lost a great deal of what was and is Christian worship from the beginning.
And this change, this loss, is relatively very recent.
