St. Joseph Catholic Church was established in 1892 as a canonical parish within the Archdiocese of New Orleans, marking the beginning of a rich legacy of faith in the Iota community. Over the decades, the parish has flourished and now stands as a vibrant and active community within the West Region of the Diocese of Lafayette, Louisiana. With more than 800 families—representing over 2,200 parishioners—St. Joseph continues to be a spiritual home where generations gather in worship, prayer, and service through the Sacramental life of the Church.

As part of its commitment to Catholic education, St. Joseph Church is the owner parish of St. Francis Elementary School, which sits adjacent to the church, and is one of seven owner parishes supporting Notre Dame High School of Acadia Parish in Crowley.

In addition to the main parish church, the faith community is also served by St. Michael Chapel, a mission church located on Egan Highway beside Egan Elementary School. The current chapel structure was completed in 1981 under the leadership of Fr. John Hassink, who lived in residence at St. Michael from 1974 to 1986 and provided dedicated pastoral care to the families of that area.
