This is the Thursday in Holy Week (the week leading up to Easter). The day is a time for remembering The Last Supper. The name comes from the Latin word “Mandatum” for “commandment” as Jesus said, “I give you a new commandment; that you love one another.” At the conclusion of this service, altars are stripped of any ornamentation and crosses are removed or veiled to mark the solemnness of the occasion. In the German it is known as “Grundonnerstag” or Green Thursday.
