Who did He say that to? Ordinary people or his chosen Apostles? (ie. the ordained)
I don’t recall anyone kneeling at the last supper.
How do you know? Despite Da Vinci's painting. We don't know what the scene actually looked like at such a profound moment. If the last supper is the final criteria maybe you should have your feet washed then each week by the priest. They also ate lamb at the Last Supper, why don't we do that? The priests also didn't get paid at the last supper. We should probably remove that later tradition as well.
What is the basis for your objections, other than a (lower case) tradition from the middle ages?
It's the priests that have maintained those forms of reverence and respect that have continued to save souls and work miracles like the Apostles, not the hootenany priests gazing out with their dead eyes and hollow voices clinging for some "social" experiment to believe in.
So only priests are to receive the Eucharist?
How do you know?
We do know how the traditional passover meal was eaten.

It is the Church that maintains the Traditions. It is the priests who create their own traditions.
