Holy Thursday: The Mass of the Lord's Supper Explained
Holy Thursday begins the Sacred Triduum, the three-day celebration of Christ's Passion, death, and Resurrection. At the evening Mass of the Lord's Supper, Catholics remember Jesus instituting the Eucharist, giving an example of humble service, and praying before his arrest.
What the Church celebrates
At the Last Supper Jesus gives the Church his Body and Blood under the signs of bread and wine and commands the apostles to do this in remembrance of him. The washing of feet shows that Eucharistic worship must lead to service. The liturgy moves from the table toward the garden, not straight to Easter joy.
The biblical roots
John 13 describes Jesus washing the disciples' feet and commanding them to love one another. The institution narratives in Matthew 26:26–29, Mark 14:22–25, Luke 22:14–20, and 1 Corinthians 11:23–26 connect the Eucharist with Jesus' self-offering. Paul says the Church proclaims the Lord's death whenever it celebrates the meal. Read in Scripture: John 13:1–15; Luke 22:14–20; 1 Corinthians 11:23–26.
How Catholics observe the day
The Holy Thursday Mass usually includes the washing of feet and a procession to a place of repose for prayer. The altar is stripped afterward, and the liturgy has no usual final blessing; the assembly continues into Good Friday. Holy Thursday is not a separate holy day of obligation, though the Mass is central to the Triduum. A feast or solemnity does not automatically make a weekday a holy day of obligation.

What to Say
“On Holy Thursday Jesus gives the Eucharist and washes his disciples’ feet. The Mass joins worship of Christ to the humble service he commanded.”
The Bottom Line
The Lord's Supper reveals a Savior who gives himself as food and kneels to serve.
