Thanks to Grandmere Mimi over at Wounded Bird, we have an answer to the matter of choosing wisely an instrument of Communion. Go toOff-Topic Allowed, for true instruments of Communion.
The only thing I would add to this is the reminder from the Knight in Indiana Jones and the Last Crusade, "choose wisely." Perhaps Off Topic Allowed might remember, silver and gold may not be the instrument, but the potters clay.
But in any event, the instruments of Communion are located more locally than in the Anglican air.
