Communion experience. Catholics believe that the consecrated bread and wine are the body and blood of our Lord Jesus Christ, while most Protestants perceive them as only symbolically true. The difference is huge. When I receive the Lord in the Holy Eucharist, I know that it has the power to actually change my soul! If the bread and wine had remained as ordinary bread and wine, I would be merely going through a ritual to help me remember the Lord's death and resurrection.
