The document discusses the significance of bread and wine in the Last Supper based on biblical passages. It describes how Jesus used bread and wine as symbols of his body and blood, establishing them as the elements of Holy Communion. He commanded his followers to partake in remembrance of him. However, in the Corinthian church some were disregarding their communion with Christ and each other by reinforcing social divisions. Paul warned this could lead to spiritual and physical harm unless they corrected themselves and embraced true community as the body of Christ.
