In August 1929, under the title of The Little River Mission Club, fourteen men and women met in a store on Northeast 79th Street near 2nd Avenue to form a new parish. Bishop Patrick Barry of the St. Augustine Diocese stated they would need one hundred Catholic families for a new parish. Three lots were purchased on the northwest corner of Northwest 2nd Avenue and Northwest 75th Street. In April 1930, ground was broken for a church. The first mass was celebrated in a wooden structure on July 20, 1930. Father William Wilkinson, S.J., of Gesu Church was the celebrant and Monsignor William Barry, P.A., pastor of St. Patrick's Church on Miami Beach, preached the homily. In October 1930, Father Patrick Joseph Roche of County Limerick, Ireland was appointed the first pastor of St. Mary's Parish. The parish area was from 36th Street North to the Broward line and from Biscayne Bay west to the Dade County line. In 1931, a rectory was constructed on the north side of the church. A parish hall was constructed in 1935 on the north side of the rectory. One week before Christmas in 1936, the church was moved to a property that had been purchased on the east side of Northwest 2nd Ave. and 75th Street. The wooden church was then remodeled and enlarged by moving the sanctuary back and adding two wings. Capacity after the remodeling was 600 persons. The first ceremony in the renovated church was the Sacrament of Confirmation by Bishop Barry in February 1937. In 1953, Father Roche retired and Father Patrick J. Donoghue was appointed pastor. The groundbreaking ceremonies for a new church were held in 1955. Cardinal Edward Mooney of Detroit, Michigan, dedicated the new church building on January 27, 1957. The church dome was seven stories above the altar. A southwest corner tower was twelve stories tall. The two mahogany doors at the entrance were high. The ceiling over the altar was high. The nave was long, wide, and five stories high with a foot main aisle and two side aisle altars. On August 13, 1958, sixteen counties of Southern Florida were detracted from the Diocese of St. Augustine to form the new Diocese of Miami. St. Mary's Church was announced by the Vatican as the new Cathedral. On October 7, 1958, Auxiliary Bishop Coleman F. Carroll of Pittsburgh, Pennsylvania, was installed as the first bishop of Miami. Shortly thereafter, renovations for the cathedral began including the addition of a bronze bell weighing more than two tons, and the installation of the Cathedral's first pipe organ. In 1966, Monsignor David Bushey, the newly appointed rector, completed work on a new rectory with new offices and living quarters. A new parish hall was built in 1967. On June 13. 1968, Bishop Coleman Carroll became the first Archbishop of Miami and Metropolitan of the newly created province. Final funeral services for Jackie Gleason were held at St. Mary's Cathedral in 1987.
