Holy Thursday- What remarkable thing did Christ perform on this day?

He ate with His apostles the Paschal lamb which was a type of Himself; it was eaten with bitter herbs and unleavened bread; they ate standing with clothes girded, and staff in hand, in rememberence of the hurried escape of the Israelites from Egypt. (Exod. 12) After having eaten the Paschal lamb our Lord, with profound humility, washed the feet of His apostles, exhorting them to practice the same humility and charity; afterwards, He gave them His Flesh and Blood under the appearance of bread and wine, for spiritual food and drink, thus instituting the Most Holy Sacrament of the Altar, the Sacrifice of the Mass, and the priesthood; for when He said to the apostles: Do this in commeroration of me, He ordained them priests.  After this He held His last discourse in which he particularly recommended brotherly love; said that beautiful, high-priestly prayer, in which he implored His Heavenly Father particularly for the unity of His Church.  He then went to the Garden of Gethsemane on the slope of Mount Olivet, where He commenced His passion with prayer and resignation to the will of His Father, suffering intense, death-like agony, which was so great that He sweat blood.  Here Judas betrayed Him into the hands of the Jews, by a treacherous kiss.  They bound Him and led Him to the high-priests, Annas and Caiphas, where He was sentenced to death by the council, and denied by Peter.
