This PowerPoint set offers imagery, words and Scripture related to an event during the Last Supper when the practice of the communion was first instituted. The bread represents the broken body and the cup represents the purifying blood.
In addition, the set includes a slide with the Scripture from Matthew 26:26 and 28: "Take, eat; this is My Body. Drink from it, all of you. For this is My blood of the new covenant, which is shed for many for the remissions of sins."
