And taking bread, he gave thanks, and brake; and gave to them, saying: This is my body, which is given for you. Do this for a commemoration of me. In like manner the chalice also, after he had supped, saying: This is the chalice, the new testament in my blood, which shall be shed for you. - Luke 22: 19-20
Yes, remembrance, not an sacrifice unless you count the offering of your time to do it.
