The activities of John Wheatley's Catholic Socialist Society have been analysed in terms of liberating Catholics from clerical dictation in political matters. Yet, beyond the much-discussed clerical backlash against Wheatley, there has been little scholarly attention paid to a more constructive response offered by progressive elements within the Catholic Church. The discussion that follows explores the development of the Catholic social movement from 1906, when the Catholic Socialist Society was formed, up until 1918 when the Catholic Social Guild, an organisation founded by the English Jesuit Charles Plater, had firmly established its local presence in the west of Scotland. This organisation played an important role in the realignment of Catholic politics in this period, and its main activity was the dissemination of the Church's social message among the working-class laity. The Scottish Catholic Church, meanwhile, thanks in large part to Archbishop John Aloysius Maguire of Glasgow, became more amenable to social reform and democracy.
