Why do protestants use crackers and grape juice during communion?

Protestants use crackers and Grape Juice during communion as symbols of the body and blood of Christ, reflecting Jesus' Last Supper. The use of unleavened bread (crackers) represents purity and the sinless nature of Christ, while grape juice serves as a non-alcoholic alternative to wine, making communion accessible to all, including those who abstain from alcohol. This choice emphasizes a focus on the symbolic meaning of the elements rather than their physical properties.
