Since 1928 Catholics in Marshfield attended Mass at either St. Mary's in Scituate or St. Theresa's summer mission in Humarock. By the 1940's nearly 300 families were attending Mass regularly at St. Theresa's. In 1944 Reverend Edmund Moran was appointed by his eminence Richard Cardinal Cushing as Pastor of Marshfield Hills. Upon his arrival, Fr. Moran saw that the remote location of St. Theresa's Chapel would not be suitable for a new parish. A better location with improved access to the community had to be found. A barn, on Rt. 3A in Marshfield Hills, which was formerly used by W. Torrey Little as an antique shop became the first site for the new parish.
Father Moran fulfilled a dream of his by naming the parish after the patron saint of his deceased mother St. Christine. It was the only parish in the Archdiocese dedicated to this saint.
