The Triduum Sacrum refers to the three Holy Days of Maundy Thursday, Good Friday and Holy Saturday.  In origin, the services which mark these Holy Days go back to the early centuries of the Christian religion.

Maundy Thursday is concerned with the Institution of the Eucharist by Our Blessed Lord in the Upper Room and with his agony in the Garden of Gethsemane.  The Liturgy on Good Friday is pre-occupied with the Crucifixion of the Saviour.  The Easter Vigil on Holy Saturday celebrates his Resurrection and our own sharing of his risen life through our membership of his Church.

In these three great days, therefore, we share with Our Blessed Lord his sufferings and his triumph, from the Upper Room to the Easter Garden.  In so doing we experience in our souls the salvation he has won for us, and we renew ourselves so that we may go with him into the world again, there to walk in newness of life.
