Ministries and Programs


Liturgical Ministries

Lectors: Lectors proclaim the Word of God at each of our weekend liturgies. At the family Mass, we also have teams of older children and parents. Training is provided.

Eucharistic Ministers: Eucharistic Ministers lovingly bring the body and blood of Christ to all parishioners at each weekend Mass. Eucharistic Ministers should be fully initiated Catholics. Training is provided.

Usher: Ushers provide assistance with the weekly collection and assist in the coordination of the bringing forward of the gifts.

Altar Servers: Adults and children, grade 4 and above, can serve at any Mass of the weekend. Training is provided.

Greeter: Greeters are utilized during Christmas, Easter, Holy Week and other special Masses. They simply warmly welcome parishioners and guests and distribute worship aids. Ideal for individuals and families.

Music ministry at St. Peter’s helps to enhance the liturgy through song. The 4pm Saturday Mass enjoys the music of a traditional choir. Rehearsals are each week on Saturday at 3pm.  We have a Children’s choir during the school year at the 9 am Mass, rehearsal is at 8:30 am. The Sunday 5 pm Mass enjoys music from a contemporary choir. Rehearsal is 4 pm on Sundays.

 Religious Education and Faith Formation Ministries

 Ministry to the Homebound and Elder Care Facilities

A group of parishioners from St. Peter’s Parish bring communion to people who are in nursing homes and assisted living facilities in our area, and also to people who are homebound due to illness or disability. This is a wonderful way to share our Eucharistic banquet with those who are nearby but unable to be with us.

If you are interested in exploring this ministry, Deacon Tim O’Donnell and his wife Elke will provide training and help with the logistics. Please contact Deacon Tim at or 617-897-1148.

 Pastoral Council & Finance Council

St. Peter’s has active Parish and Finance councils that meet periodically throughout the year assisting the Pastor in areas of parish life.


RCIA is the process through which adults are initiated into the church through the sacraments of baptism, confirmation and Eucharist, and baptized Christians from other denominations come into full communion with the Catholic community. Please call Anna Molettieri at 617-547-4235 x17 or email at
