Here the Holy Apostles sit with Jesus Christ at His last Passover meal, which initiates a great Mystery, the first Holy Communion as revealed by God to us. St. John leans on His Master’s breast, while Judas reaches for the dish showing who would betray Christ later that same night. The giving of His Body and His Blood to His Disciples before His Passion in Holy Communion brings the mystical and everlasting Kingdom into the life of the Apostles, who were the foundation here on earth of His Holy Church. This is why the title of this icon and this event is not the Last Supper, which is already finished when the Mystery begins, but the Mystical Supper of Christ.
Only Judas is shown in profile, as only he had a hidden side of darkness, not open and loving as the other Apostles, who are shown with both eyes visible, a common iconographic form. We must remove through openness and love any hidden malice or selfishness from our own hearts to join them in preparing for this Mystical event. The table is rounded to show that there is always room for every one of us to come and partake of Him.
