The Eucharist has a real connection to the Last Supper. The Last Supper was the last time Jesus and his disciples got to spend together before Jesus was nailed to the cross the next day. The Last Supper was the first time Jesus and his disciples received the Eucharist. When Jesus gave the bread and wine to his diciples he said 'take this for this is my body and blood which has been givin up for you'. The Last Supper was held in Jerusalem. So over the years we have repeated the Eucharist from this day.
