Final answer:
During supper in the Gospel of John, Jesus washed the disciples' feet, while the Synoptic Gospels describe him blessing bread and wine, instituting the Eucharist. The Last Supper included Jesus predicting his betrayal.
Step-by-step explanation:
In the Gospel according to John, Jesus performed the act of washing the disciples' feet during supper, demonstrating humility and service. However, the reference to the act of blessing bread and wine originates from the Synoptic Gospels of Matthew, Mark, and Luke, where Jesus institutes the Eucharist at the Last Supper. There, Jesus blessed bread and wine, offering them as his body and blood, 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 event holds significant religious importance, as it is interpreted as the first celebration of the Eucharist, a fundamental sacrament in Christianity. The Last Supper that Jesus shared with his disciples also included a moment where he foretold his betrayal, creating a pivotal moment before his crucifixion. It is a scene often depicted in religious art and observed during Holy Thursday services.
