One Mass is celebrated on Holy Thursday, the beginning of the Sacred Triduum, the three days that follow the journey of Jesus from life to death to resurrection. Holy Thursday is a commemoration of the Last Supper—the meal Jesus shared with his disciples. The meal that Jesus and his disciples shared and that we commemorate this Holy Thursday is regarded in the Church as the institution of the Eucharist. Finally, the washing of the disciples’ feet, recorded in the gospel of John , is re-enacted by priests and parishioners every Holy Thursday as a reminder of the obligation that we have as Christians to be first and foremost servants to one another.
