I'd love for you to expand on this.We had communion Sunday. The latest thing we've done at our church is to purchase a prepackaged little cup of juice that has a wafer sealed inside the cellophane top which, in turn, seals the juice. The wafer looked like Styrofoam, and I wondered if it was truly edible. I did ingest it. The juice smelled weird, so I didn't drink it. My son said the wafer was not like Styrofoam because he could actually use it as a guitar pick. At that point, our conversation was beginning to sound like an irreverent criticism, so I felt I should remind us that regardless of the quality, it represented something else. The very phrase I used was it's a symbol.
