Christ's "mandate" is commemorated on Maundy Thursday---"maundy" being a shortened form of mandatum (Latin), which means "command." It was on the Thursday of Christ's final week before being crucified and resurrected that He said these words to his disciples:
"A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another" (John 13:34).
