The Table of the Last Supper, for Roman Catholics, is more than a historical artifact. It is a living symbol at the heart of Christian worship, recalling the origins of the Eucharist and the enduring call to unity, sacrifice, and communion. Whether imagined as a low, U-shaped triclinium, a semicircular table, or the familiar rectangular board of Renaissance paintings, its meaning endures in the liturgy, art, and spiritual life of the Catholic Church.
