Every Sunday, in the middle of the hour, the trays go around. Unleavened bread and the fruit of the vine, passed hand to hand down the row. It takes about six minutes and it is the part of the service we would defend last.
Not a ceremony we perform, a memory we keep
The early church did this on the first day of the week, and we have never found a good reason to do it less often. Familiarity is the risk, and it is a real one — anything you do fifty-two times a year can go automatic. But the answer to that is attention, not scarcity. You do not eat dinner with your family less often to keep it meaningful.
Acts 20:7
