Luk 22:19 And he took bread, and gave thanks, and brake it, and gave unto them, saying, This is my body which is given for you: this do in remembrance of me.
Remembrance means 1. The action of remembering something.
2. The action of remembering the dead, esp. in a ceremony
A memorial is an object which serves as a focus for memory of something, usually a person (who has died) or an event.
Logia, where we get the word Eulogy, means to speak good of the dead.
So a part of remembering Jesus is to speak well , good of him and to remember His death.
