The word AYRUB [Heb translit] has the idea of sharing communal bread in a communal place [Lightfoot, Talmud]. The place would be a common public place like a court or forum or barn. They would all bring their common/ shared bread into the common/ shared public location and eat it together. In John 21 we see this, except now, we're sharing the bread which He Hinself has privided (we didn't contribut anything), we just come and He provides the bread (which speaks of Him giving Himself). Christ, is what we have in common with each other, and communion is the coming together, in a public open forum of fellowship (KOINONIA) such as a service, meal, q&a rap session, or home bible study, to enjoy and express that Bread of Life.
