Like Coral Gables itself, the church was built by well-to-do Americans; for most of the 20th century, members were predominantly
Irish-American, politically liberal, and supporters of the
Democratic Party. Membership was perceived as a "gateway to social advancement." In 1990 a rift developed between the parish priest, Father Kenneth Whittaker, a former
Lutheran who had converted to Catholicism, and parishioners who did not attend church regularly. Father Whittaker enforced new rules, including expelling children from the parish's socially and academically prestigious school if their parents failed to attend
Mass regularly and on time. The issue escalated, with angry parishioners picketing the church and Father Whittaker refusing to
confirm or give
First Communion to children whose parents were lax in attending Mass. The composition of the congregation changed with the arrival of an enormous wave of
Cubans who immigrated to Miami after
Fidel Castro's 1959 rise to power in the
Cuban Revolution. More than half of the parish and more than half of the children in the school were Cuban-American in 2000. The church became known as a center of political conservatism, with many members active in the
Republican Party. The membership is "predominantly"
Cuban and
Cuban-American. Historian Darryl V. Caterine credits their arrival with sparking a "dramatic religious revitalization" of Catholicism in South Florida. According to historian Caterine, the 1991 arrival of the Carmelite Sisters of the Most Sacred Heart of Los Angeles sparked an intense revival of both Cuban identity and Catholic commitment among the members. Members described the arrival of the Carmelites as a kind of "miracle" in which their community was "transformed" by a renewed spirituality. In 1999 over 40,000 people came to the church to venerate the relics of
St. Therese of Lisieux, part of a world tour of the relics to inspire spirituality at the millennium. ==Notable parishioners==
