he most popular theory for the origin of the word "Maundy" is that it is a bastardization of the beginning of the Latin text of John 13:34, which reads, "A new command I give you: Love one another. As I have loved you, so you must love one another." In Latin, the verse reads, "Mandatum novum do vobis ut diligatis invicem sicut dilexi vos." "Maundy" is drawn from the first word of the verse, "mandatum," which is also the origin of the English word "mandate."
