I was asked about how fellowships should organize their treatment of newcomers on the issue of tithing. In response I said:
I really hesitate to get into the internal governance of fellowships because the right belongs to the member through common consent. Because the right to govern arises from common consent, the decisions of the fellowship can be varied. Perhaps the approach will be changed from time to time based on experiences. But the fellowship has the right to decide, and then later, based on experience or discussion, to change the decision to do something else.
I would regard the close of the service as also the end of the consecration of the emblems. So that once the event/observance/service has ended, then I would think anything remaining would be just ordinary food to be used as the case may be. That was what happened to the excess loaves and fishes (Mark 6:43; Matt. 14:20; John 6:13; Luke 9:17), which were gathered and used. I wouldn’t just throw away the remainder, but I’d make use of it all. I think once the service ends then the sacred nature of the emblems likewise ends.
