Maundy Thursday is called "Maundy" because it stems from the Latin word mandatum, meaning "command" or "mandate". This refers to the new commandment Jesus gave his disciples during the Last Supper to "love one another as I have loved you," shortly after washing their feet to symbolize service and humility.
Key details about the name and day:
- The Commandment: In John 13:34, Jesus says, "A new commandment I give to you, that you love one another; as I have loved you...".
- Latin Roots: This "new commandment" is translated in the Latin Vulgate Bible as Novum Mandatum. Over time, mandatum was anglicized to "maundy".
- Washing of Feet: The day commemorates the Last Supper, where Jesus washed his disciples' feet to model humble service. This act is known as the Mandatum.
- Other Names: It is often called Holy Thursday, or in some traditions, "Sheer Thursday" (clean Thursday).
- Traditions: In the UK, the monarch commemorates this day by distributing special coins known as "Maundy money" to residents.
