Saint Jude Parish was established December 12, 1973 by the Most Reverend Walter W. Curtis, Bishop of Bridgeport, to accommodate the growing number of Catholic families moving into Monroe. An unprecedented plan involved the people of Saint Stephen Parish, Trumbull, Connecticut, in determining its division that resulted in the formation of the new Saint Jude Parish out of the original single parish that formerly covered all of the town of Monroe and part of Trumbull. Under the division plan, Saint Jude Parish acquired the Saint Stephen School, which became the Saint Jude Parish Center, and the 17 acres of land. Saint Jude Parish is entirely within the Town of Monroe from Cutlers Farm Road east. 

In selecting the name for the new parish, a unique means was employed which also involved parishioners. A ballot was provided that contained the names of 14 saints and Saint Jude was the majority choice of the people as the name for the new Monroe parish. This is the first instance of the use of Saint Jude who was one of the Apostles, as the name for a parish within the Diocese of Bridgeport. 

The historical spiritual venture took place in the Saint Jude Parish Center on December 15, 1973 at the 5:15 Mass whereby Bishop Walter W. Curtis installed Rev. Arthur Norton as the first pastor of Saint Jude Parish. 

Rev. John Sabia was installed as the second pastor on September 10, 1978. In November of that year a Parish Food Pantry was established to serve the needy. Ministry of Hospitality was also formed to welcome people who moved into the Town of Monroe

Since the parish had many young parishioners it was deemed to have a Summer Vacation Bible School. This would be the beginning of a long history of Vacation Bible school for Saint Jude Parish. 

The Saint Jude Annual Novena was established in the month of October to prepared for the Feast of Saint Jude on October 28th

With the burning of the mortgage of the rectory, the consensus of the parishioners was to begin thinking of building a new church. In November 1980 a Building and Development Committee was formed to plan for building a Saint Jude Church.

The Mission Committee sponsored the annual Adopt an Appalachian Child for Christmas benefiting the children of Whitley City, Kentucky. Now hundreds of children receive gifts each Christmas. 

On the tenth Anniversary of the parish the Parish Center was renovated for weekend Masses. Bishop Curtis celebrated the liturgy for the dedication of the altar and figure of Christ in Glory on the reredos of the Parish Center.

Construction of the new church began with the ground breaking ceremony on November 29, 1987.

The new Saint Jude Church was dedicated on October 28, 1989 at a special Mass celebrated by the Most Reverend Edward M. Egan, Bishop of Bridgeport, during which the Altar and the walls of the church were anointed with holy oil.

The year 2001 saw the completion and dedication of the Saint Jude Social Hall located in the lower church. With the beautiful stained-glass window of our patron saint, it is a wonderful location to enjoy coffee and fellowship after Mass. During the year 2001, we were also able to celebrate the burning of the church mortgage.

The years 2003-2004 saw the redesign and improvement of the sidewalks and plaza around the church. 

The Rectory Committee was established on October 4, 2000, to plan for a new rectory for the growing parish. The rectory on Monroe Turnpike was too small to accommodate another priest. Groundbreaking with Bishop William Lori, Bishop of Bridgeport was on March 21, 2004. Dedication of the new Rectory/Office Building by Bishop Lori was June 25, 2006.
