When we take communion, or break bread, or celebrate the Eucharist, the main point is to remember what Christ did for us. We eat his body and drink his blood to show that we are taking in His life which is the means to eternal life. We are forgiven and we proclaim His death until He comes. But the bread and the cup also point to unity! 1 Cor 10:16-17 says, “Is not the cup of blessing which we bless a sharing in the blood of Christ? Is not the bread we break a sharing in the body of Christ? Since there is one bread, we who are many are one body; for we all partake of the one bread.”
We sometimes miss the symbolism because it is common to use little wafers or pre-cut pieces of bread (more like crackers, actually) in communion. But the reality is that all believers are members of the one body of Christ. Think about that the next time you share in the breaking of bread!
