The Eucharist, also known as Holy Communion, Blessed Sacrament and the Lord's Supper, is a Christian rite that is considered a sacrament in most churches, and as an ordinance in others. Christians believe that the rite was instituted by Jesus at the Last Supper, the night before his crucifixion, giving his disciples bread and wine. Passages in the New Testament state that he commanded them to "do this in memory of me" while referring to the bread as "my body" and the cup of wine as "the blood of my covenant, which is poured out for many". According to the Synoptic Gospels this was at a Passover meal.
The Eucharist has been a key theme in the depictions of the Last Supper in Christian art, as in this 16th-century Juan de Juanes painting, after Leonardo da Vinci's Last Supper.
