The Mass of the Lord's Supper is held. At the Mass of the Lord's Supper, the priest (often) performs the washing of feet. The Tabernacle is empty and the Eucharist is put in a place of repose. The altar is stripped. The faithful are invited to spend time in Eucharistic adoration while the Sacrament is in repose.

On this day, when "Christ our passover was sacrificed," the Church: meditates on the passion of her Lord and Spouse, adores the cross, commemorates her origin from the side of Christ asleep on the cross, and intercedes for the salvation of the whole world.
