In the meantime, parishioners provided suggestions for a name for the new parish. St Elizabeth Seton had been canonized recently, and some parishioners suggested this American saint as a patroness.  Bishop Curtis, who had attended her canonization in 1973, confirmed the Parish name.

Once the site was selected, other committees were formed.  Area churches were visited and architects presented their concepts.  An architect from Bridgeport Connecticut,  Ed Luders, was selected, and the plans for the church building were discussed.  This resulted in the contemporary wooden beamed structure which became Saint Elizabeth Seton Church.

The Finance Committee was formed and volunteers visited parishioners to solicit pledges for monetary contributions and support.  A large donation was received from an unexpected source, Mr. Francis Martin, a devout Methodist, who had also contributed to the building of the Jesse Lee Methodist Church in Ridgefield Center.  His contribution to St Elizabeth Seton Parish was in memory of his mother, a Roman Catholic.  The window behind the main altar is dedicated to his memory.

A ground-breaking ceremony was held on September 27, 1977, a damp, humid day in late spring.  Priests, deacons, altar servers, and parishioners followed Bishop Curtis up a rough, muddy construction path. An altar boy assisted the Bishop in digging the hard ground.

Construction began in earnest with the aid of many talented parishioners.  Carmine and Mario Primiano were the general contractors, and John McMurray volunteered as clerk of the works. An unsalvageable house on the property was torn down, except for its foundation and chimney, around which the present rectory was built. The Parish Center, which contains offices for the parish secretary, and Religious Education assistants, was constructed behind it at a later date.

Among the more serious crises in the church construction occurred when a shipment of beams, manufactured in the state of Oregon, was delayed due to a rail strike. The beams arrived stripped of their protective covering and were water-stained. Members of the construction crew and Church volunteers cleaned the beams to reduce the staining.

After two and a half years of construction activity, the church began to take shape. Although much internal work remained to be accomplished, it was decided to hold Christmas services on the new site.

On Saturday December 24th 1978, the electricity was connected, the boiler was working, and the first Mass was celebrated.  Parishioners brought chairs to Church as the pews were not yet installed. The floor was covered with sawdust, a temporary barn door was the entrance, a rough-hewn altar stood on a small platform, and a family provided a creche from home. A tall spruce tree was centered behind the presidential chair: an orange crate. For the 400+ people in attendance who had approached the church from Advent Road, this stable-like atmosphere was a meaningful reminder of the nativity

Work continued, and the church building was officially dedicated on September 29, 1979. Some features of the church building include:

The Church is built in the shape of an equilateral cross. The main entrance is at the foot of the cross, with the main altar at the top which occupies the center of the elevated Sanctuary.  The two wings of the cross contain pews seating about 400 worshipers.

The permanent altar is constructed of white oak, weighs 800 pounds and cost $10,000 . It contains relics of St Stephen, the first martyr, and a bone fragment of St. Elizabeth Seton.

Above the altar, a crucifix replaced the plain pine cross in 2004.  The Corpus Christi, Body of Christ, was hand-carved in Linden wood at the Demeti Art Studio in northern Italy. It is dedicated to the memory of Deacon Bart Mauceri.

The Stations of the Cross are made of cedar shakes, and the original porcelain stations from Regan Road. A next-door neighbor, artist Adeline Anderson, dedicated eight years of her talents to paint the present Stations, and the art tapestries.

Robert Basset made the tabernacle and Fred Schreiber constructed the baptistery.

Frances Medynski remained pastor of St. Elizabeth Seton until his retirement in 1996. On August 2, 1996, Most Reverend Edward M. Egan, 3d  Bishop of Bridgeport, officiated at the installation ceremonies for Father Joseph Prince, the newly appointed Pastor. (On May 11, 2000, Bishop Egan was appointed Archbishop of New York, with subsequent elevation to the College of Cardinals on January 21, 2001. He was succeeded by Bishop William E. Lori, 4th Bishop of Bridgeport on January 23, 2001).

In December 2021 Fr. Prince retired and Fr. Alphonse Arokiam was appointed Administrator and then later Pastor.
