As a national church, Holy Trinity may consider as members anyone who lives within the Archdiocese of Boston and is of German lineage, regardless of how far away from the church they live. Parishioners of Holy Trinity Church have the following rights and privileges: their children may be baptized at Holy Trinity and make their First Communion here; their daughters may get married at Holy Trinity; they are asked to support Holy Trinity according to their means; they can, in case of sickness, call a priest from Holy Trinity; and they may be buried from Holy Trinity.

Originally founded as a diocesan parish in 1844, Holy Trinity was taken over by the Society of Jesus in 1848, and for the next 13 years the Jesuit fathers directed the parish until it returned to the control of the Archdiocese in 1961 (see History of Holy Trinity). Holy Trinity was and is much more than just an ordinary Catholic church or parish. From the earliest days it became a "way of life" for clergy and parishioners alike, complete with parochial schools (in fact, the oldest permanent parochial school in New England belonged to Holy Trinity), sodalities and other organizations with many weekly and monthly social functions (see Organizations and Schedule for more information).

For the last ten years, a vibrant and growing community of Catholics attached to the Roman liturgical tradition has also been happy to call Holy Trinity home. In 1990 Bernard Cardinal Law allowed the Traditional Latin Mass to be celebrated each Sunday at Holy Trinity at 12:00 p.m. (and on holy days of obligation at 7:00 p.m.), and later extended this indult to the celebration of baptisms, weddings, and funerals. Other ceremonies, such as blessings and churchings, are also available in the old rite.

Visitors and Newcomers are warmly invited to join us in the lower level of the church for coffee and donuts after the Sunday Masses. To be put on the Holy Trinity mailing list, please write to:
