Interesting. What would you consider to be a good answer? (Obviously nothing involving transubstantiation.)
I ask because I don't think the Lord's Supper (aka Communion) is purely symbolic with no Divine interaction. I think Christ is present with us in the event as the Body of Christ celebrating his incarnation, life, death, resurrection, ascension, present reign, and future kingdom. The act of consuming the bread and wine/juice is a holy touch point between our present state, the past, and the future in Christ.
Would I pass muster with that not-so-Baptist sounding answer?
