Or you could just come to our services and celebrate communions with fellow believers, since you reject them from yours. You know full well that you do not taste human flesh or blood when you take communion, which means you have to invent something along the lines of, "Well, it doesn't change into flesh and blood until you've swallowed it". Jesus' disciples ate the bread and drank the wine, and it's not recorded anywhere that they went, "What the heck, this is blood!".
IOW, it's a spiritual understanding, not a physical one.
