Maundy Thursday marks the end of Lent and the beginning of the sacred "Triduum” of Holy Week. These three days are the holiest days of the Christian year. The name "Maundy" comes from the Latin mandatum, ‘commandment’, because of the use of John 13.34 as the Entrance Antiphon;
‘I give you a new commandment; that you love one another.
Just as I have loved you, you also should love one another.’
At this Mass, the Priest washes the feet of twelve members of the congregation to symbolise Christ’s washing of his twelve Apostles. This Mass stresses the importance Jesus puts on humility and service within the Church. Also emphasised are the fundamental importance of the Eucharist and the sacrifice of Christ’s Body, which we now find present in the Blessed Sacrament.
O Bread of Heaven, beneath this veil
Thou dost my very God conceal:
My Jesus, dearest treasure, hail! (St Alphonsus)
At the conclusion of the Mass, the Blessed Sacrament is transported to the Altar of Repose and we are invited to continue adoring the Lord Jesus present there until midnight, just as the disciples were invited to watch with the Lord during his agony in the garden of Gethsemane.
After tonight, no Mass will be celebrated again in the entire Church until the Easter Vigil celebrates and proclaims the Resurrection of the Lord Jesus Christ.
