Final answer:
During the Last Supper, Jesus instituted the Eucharist, where bread and wine become symbols of His body and blood, establishing a new covenant and commemorating His sacrifice.
Step-by-step explanation:
During the Last Supper, Jesus instituted the sacrament of the Eucharist — a fundamental rite for Christians symbolizing Christ's Last Meal with His apostles prior to His crucifixion. Described in the New Testament, Jesus blessed bread and wine, giving them to his disciples, saying, "Take, eat; this is my body" and "Drink from it, all of you; for this is my blood of the covenant, which is poured out for the forgiveness of sins" (Matthew 26).
This act is considered the origin of the Eucharist, also known as Holy Communion or the Lord's Supper, where Christians eat bread and drink wine as a symbol of Christ's body and blood, and to remember His sacrifice for humanity. Historical representations in art, such as Leonardo da Vinci's The Last Supper, have further immortalized the significance of this event. The institution of the Eucharist during the Last Supper highlights Jesus' effort to establish a new covenant through His sacrifice, which is a key aspect of Christian theology and practice.
