Based on normal practices each person would have their CUP: in the Jewish/Babylonian Passover each person was to drink so much that they could not tell one person from another.
However, the Lord's Supper was instituted during the Feast of Unleavened bread which tended to run together with Passover: you KILL the passover you know.
Even so historically ALL churches were one cuppers or one chalice people. So was the church of Christ, Baptist, Methodist etal. G.C. Brewer took credit for introducing the multi cup probably because he had a friend with surplus shot glasses. So, to try to make that a wacko one cupper hate crime when probably MOST people number wise use one cup.
In North Alabama we were a two glasser church until lots of people came down with TB so we converted. However, as with all of the HATE THE CONSERVATIVES, it was the ONE CUPPERS who did not change from the historical position. It was the SHOT GLASS people who IMPOSED something which sowed the discord. Therefore, by all HONEST measures, the multi-cup are the SECTARIANS. Since they IMPOSED they should be man enough to take the blame and not whine. The new ANTism can easily cause people to believe that THEY sowed discord by IMPOSING just one cup. It is a wacko world.
Once they became the SECTARIANS (as with the music issue) it becomes easy to focus on hate and blame those who were never forced to BEGIN doing what they had NEVER done which are called the sectarians. That is the old GUILT CLAUSE. "I know I shot you in the heart but YOU caused the fuss by squirting blood on my dancing slippers."
As I remember part of the SUNDAY SCHOOL MOVEMENT especially by the Disciples demanded that it NOT be run by the elders and that everyone use the Standard Material. We would have a lot more adults if we didn't force them to do cut outs and paste ups even into the 12the grade one Youth Minister told me
