Comparing the history of the Catholic Church in Australia and the United States, John Tracy Ellis noted, both communities an environment unfriendly to their religious faith nurtured a separatist spirit which varied according to time and place but which in general bred a so-called mentality.1 The Catholic ghetto was sustained to a considerable extent by the establishment of denominationally-based organizations and institutions which reinforced the Catholic worldview and reduced the need for Catholics to associate with non-Catholics in their daily lives. Moreover, as Martin Marty has pointed out, it was not only Catholics who developed intellectual ghettos and denominational institutions which distinguished them from the dominant culture of the United States= Similar patterns developed in central and north-western Europe, finding their most extreme expression in the pillarization (verzuiling) of Belgium and the Netherlands. From the later nineteenth century until the 1960's, Catholics, Protestants, and Socialists developed more or less self sufficient parallel societies orpillars. Each pillar maintained its own cultural associations, sports clubs, educational institutions, social security organizations, trade unions, political parties, newspapers, and broadcasting networks. Collectively, the pillars were thought of as supporting the nation, and governments encouraged their development (for example, by subsidizing denominational schools) because it was assumed that minimizing the contact between antagonistic communities like Catholics and Calvinists was necessary to avoid social conflict.3 New Zealand Catholics, as a minority group, needed to maintain their religious integrity without unduly antagonizing the Protestant majority At 164,133 in 1921 and 195,261 in 1936, Catholics made up just over thirteen percent of the non-Maori population of interwar New Zealand. In 1921 seventy-six per cent of the population were either Anglicans, Presbyterians, or Methodists.4 Catholics' religious beliefs and practices, based on the evolving patterns of contemporary European (and North American) Catholic spirituality, marked them out as quite different from Protestants, including Anglicans whose church was overwhelmingly evangelical in tone. Moreover, the Catholic population as a whole was neither wealthy nor well-educated although some Catholics achieved prominence in business or politics, including Sir Joseph Ward (Prime Minister, 1906-1912, 1928-1930) and Michael Joseph Savage (Prime Minister, 1935-1940), who died in office, having recently returned to the faith of his childhood. As in other countries, the maintenance of Catholic identity by means of numerous lay organizations and religious institutions, especially during the interwar years, constitutes a prima-facie case for supposing that there was at least a Catholic in New Zealand. Catholics in Timaru, for example, had a particularly well-organized parish of 2,350 souls in 1926.5 Lay organizations listed in 1928 included the Children of Mary, the Sacred Heart Sodality (for women), St. Anne's Guild (a women's charitable society), an Altar Society, the Hibernian Australasian Catholic Benefit Society, a Girls' Club for former pupils of the school, a choir, and the Catholic Club. Affiliated to the latter were St. John's Tennis Club, the Celtic Cricket and Football Club, St. Patrick's Rifle Club, the Catholic Choral Society the Literary and Debating Club, the Dramatic Club, and the Swimming Club.6 A review by B. J. Barnao of Catholic organizations in Wellington in 1936-when the Catholic population was 22,679'-discussed a number of pious and charitable associations: the Holy Name Society, the Children of Mary Sodality, the Sacred Heart Sodality for women at St. Joseph's parish, the St. Vincent de Paul Society, the Seamen's Institute, the Third Order of St. Francis, and the Third Order of Mary. Barnao also referred to Catholic Scouting, the Hibernian Benefit Society, the Catholic Readers' Club, the Catholic Sociology classes, and the Catholic Students' Guild. …
