The season of Lent officially ends at the celebration of the Mass of the Lord's Supper on Holy Thursday.  This beautiful Mass marks the beginning of the summit of our liturgical year known as the Triduum which is Latin for three days.  Though the celebration spans the period of three days, our liturgies during that time constitute one continual celebration - "liturgically one day unfolding for us the unity of Christ's Paschal Mystery". The liturgical services that take place during the Triduum are the Mass of the Lord's Supper, the Celebration of the Lord's Passion on Good Friday, and the Mass of the Resurrection of the Lord at the Easter Vigil.  We hope you can join us for this most beautiful and holy event!

Please note:

  • the Mass schedule for Palm Sunday and Easter Sunday differ from the regular Sunday Mass schedule
  • as there are no Masses held in the morning during the Triduum, Morning Prayer is held at 8am instead on Holy Thursday, Good Friday, and Holy Saturday


This story never gets old. How quickly things change, from “Hosanna” and palm branches to “Crucify him! Crucify him!” During the Mass this weekend we remember the Hosanna with palms and then listen attentively to Mark’s gospel proclaiming Christ death.

Chrism Mass -  Each year parishioners across the Archdiocese join in celebration at this special liturgy.  At this Mass, Cardinal Séan blesses the oils to be used in the year ahead for the Sacraments of Baptism, Confirmation, and the Sacrament of the Sick. These oils will be presented to our parish during the Mass of the Lord’s Supper on Holy Thursday.  This Mass is also a beautiful moment of communion between the priests and their bishop as they renew their promises made at their ordination. This will be the first Mass in the newly renovated Cathedral of the Holy Cross, Boston. Starts at 11am.  A carpool leaves St. Augustine Church parking lot at 8:45am - call 978-475-0050 to sign up.



Evening Mass of the Lord's Supper - a joyful celebration commemorating the institution of both the Eucharist and the priesthood as well as the washing of feet. After this Mass, the altar is stripped and the Blessed Sacrament is processed over to the parish center for individual prayer in recognition of Christ’s coming passion.
