In partaking of the bread and the cup, Christ’s disciples are to remember his sacrifice on the cross of Calvary as he gave his body and shed his blood for our sins. Baptists believe the Bible teaches that the elements used in the Supper are not literally the body and blood of Christ.
They are symbols of his body and blood. In eating the bread and drinking from the cup, a person does not actually partake of Christ’s flesh and blood. Rather, it is an opportunity to obey a command of Christ and to recall his sacrifice for us, his presence with us and his certain return (1 Corinthians 11:24-28).
