First - Welcome!!
I believe the word they have translated as “memory” is really closer to something like “re-presented” (as in, “making present again”)…
The problem is, this too would likely cause confusion. To most causal listeners, it would just sound like “represented” (ie, symbolized).
If the priest was careful to pronounce “re-presented” absolutely correctly, it would still be problematic – since then it sounds like the Catholics really are “killing Christ” all over again (a charge levied against them for centuries by Protestants). This, of course, is false – the Mass is not
another sacrifice, it is a “
re-presentation” of the One Sacrifice of Christ at Calvary. Each Mass enters into the eternal Sacrifice, all Masses participate in Calvary – this is why every Mass, even the ones that we are not present at, or the ones that a single priest celebrates, all grant graces to us all. We are truly one Body in Christ!
One might then say that the word “memory” could be replaced with the phrase “to make me present (again)”… this again has the same kind of problems as above… the Protestant (or un-educated Catholic) will then say, well, isn’t Christ present all the time?
“Memory” is an accurate translation, though it does have a far too shallow meaning to most English-speaking people I’m afraid. When you remember something you are “making it present” in your mind once again. However, in this case, in the Mass it’s not just in your mind - you remember the words of consecration and the priest’s action of saying those words “makes present” (with the help of the Holy Spirit) Jesus Christ, Body Blood Soul and Divinity, under the appearances (accidents) of bread and wine.
Personally, I would prefer them to have used the “re-presentation” or the “to make me present” phrase… even though there are problems with those too, perhaps it would have been easier to catechize people as to the fullness of their meaning (as opposed to the word “memory” where most people just take for granted that they obviously know what that word means… and it means “symbolic!”

)
However, I also realize I am not the Church, and only the Church has authority in these matters. “Memory” it is, and so our task is to be prepared to answer correctly when people ask about it – to learn our faith in spite of what we want to believe, or even what we assume we believe!
