Today we look at the elements of the lords supper. When Jesus said this is my body, did he literally mean the bread turns into his body or was he speaking in a spiritual sense?
The bread is a visible sign of a spiritual reality. It points us to that day when we will truly eat and drink of the lord… So even though Christ said this is my body, our spirits truly are commune and feed on Christ. However, The bread remains bread and the wine remains wine.
This is contrast with the doctrine of transubstantiation where they believe in a literal transformation of bread to Christ body and wine to Christ blood. However, The bread remains bread and the wine remains wine.
The visible elements in this sacrament, when they are properly set apart for the uses ordained by Christ, have such a relationship to Christ crucified that they are sometimes called—truly, but only sacramentally—by the name of the things they represent, namely, the body and blood of Christ. This is true even though in substance and nature they still remain truly and only bread and wine, as they were before.
