This unity serves as a reminder of the fundamental belief in the body of Christ and the interconnectedness of believers as part of a larger spiritual family.

In the context of communion, the cup symbolizes the blood of Christ shed for the forgiveness of sins. By blessing the cup, believers acknowledge and express gratitude for the atoning work of Jesus on the cross.

The Bread - The breaking of bread in communion signifies the body of Christ broken for humanity. This act serves as a tangible reminder of Christ's physical suffering and sacrifice, as well as the spiritual nourishment and sustenance that believers receive through their faith in him.
