When it comes to the Memorial, among other things, I was always puzzled by how fussy they were about the type of wine, the bread recipe and the day and the hour it was held. They wanted everything to be exactly like it was at the original event, yet weeks beforehand, they'd go around the community inviting complete strangers to the Memorial even though there was no indication that anyone but Jesus current associates were in attendance back in the day. There is no indication in the Bible that the Apostles went around inviting anyone else to attend the Last Supper.
In terms of accuracy, the original meal was held in an upper room and they were all physically together in it. How true to the original can they be in this regard when everyone is attending via Zoom.
