HWB: Different tradition, I know - but I've taken part in communions where the bread is white, brown, leavened, unleavened, crackers, wafer - whatever. Equally I have partaken of 'wine' which is alcoholic, or non-alcoholic (as we had several recovering alcoholics with us and wanted them included in the sacrament), or even, on a very memorable occasion when commemorating an illegal conventicle at Airdsmoss, whisky. I enjoyed that.... Seriously, though, since my tradition rejects transubstantiation, the actual ingredients of the elements don't matter. The nature of the act itself in whatever setting, however, is always sacred.
