“Remembrance only is a very recent innovation”.
The ceremony Jesus instituted was quite simple, not the ritual you refer to. And it was THAT he said to do in remembrance of his death.
“And without the Eucharist and Mass, worship becomes something quite different - lacking in worship consisting only of prayer, lecture and song.”
Doing something in remembrance does not change what you are doing. It’s not mutually exclusive: Holy Eucharist and doing in remembrance. So the point is a non sequitur.
ABSOLUTELY INDEED.
