St. Teresa's Parish officially began in 1924 with the appointment of Father Harold A. Summers, then pastor of St. Patrick's Parish,

to attend to the spiritual needs of the people of Mundy Pond. By 1928, a census showed that there were 150 Catholic families with approximately 750 people in the community. Though Father Summers looked after the needs of the vicinity for several years, it was not until October 1, 1930, that he was appointed the first resident priest of the new parish. By Christmas of 1932 the parish residence was ready for occupancy and on June 12, 1938, the first parish church (today's parish hall) was blessed by Archbishop Roche.

Prishioners of St. Teresa's have had a long term relationship with the sisters of Mercy and the Redemptorists. The sisters were welcomed to the parish in 1944 when they took over the administration of the school ( the area had a Catholic school as early as 1899), and the Redemptorists officially began to minister in the parish on Sunday, October 21, 1956. The first Redemptorist pastor who served at St. Teresa's was Father Patrick Mann wh, together with his assistant Father Francis Maloney, set a pattern of working with and for the people that continues to this day. On Sunday May 27, 1962, the sod was turned for a new church and monastery. Nearly 2 years later, October 25, 1964, the new church opened on the feast of Christ the King.

At present St. Teresa's with a Catholic population of 12000, is one of the biggest Roman Catholic parishes in the Archdiocese of St. John's. the area has grown from is original 750 inhabitants to over 26000. The parish register confirms 9 535 persons on its lists, and seeks to care for the needs of the 3494 families who see St. Teresa's as their spiritual home.
