Missionaries from Tilton, New Hampshire conducted the first Catholic services in Plymouth in 1901 at the home of one of the pioneer families of the parish, Mr. and Mrs. Edward Coffee.  Three years later, the newly established St. Matthew Parish became a mission of St. Agnes in Ashland, just a few miles to the south.

The congregation increased in numbers and the Universalist church, which was closed at that time, served for the parish masses during the next three or four years. The picture at the right of the old Universalist church is taken from an 1886 drawing.

A lot was purchased in 1911 on School Street in Plymouth and a year and a half later, on October 12, 1912, Saint Matthew Catholic Church was dedicated by Bishop Albert Guertin.

The first pastor, Rev. John Brewen, was appointed in the summer of 1916.  Father Brewen fell ill and died during the influenza outbreak of 1918, and during the next three years the parish was administered by the pastor in Ashland.

The Rev. Michael R. Griffin was appointed pastor in 1919 and the rectory at the corner of Highland and Langdon streets was purchased.

St. Matthew, St. Agnes, St. Timothy and Our Lady of Grace were merged into Holy Trinity in the summer of 2006.
