ABSTRACT The role of the Catholic Church as conservative watchdog in the ‘culture wars’ of the 1970s and 1980s, with regards to issues of contraception, abortion and divorce, has perhaps obscured its more complicated stance on social issues. This article focuses on a significant shift in thinking with regards to the unacceptability of poverty and the role of the state in welfare provision in the 1960s and 1970s. It argues that in Ireland Catholic ideas, given a public platform by the (...) Second Vatican Council, had a significant impact on clerics and people, creating social justice agendas that could both influence government policy and inspire its critique. While obviously not solely responsible for the shift to the left that occurs in this period, this article highlights the significance of Catholic ideas in shaping attitudes to poverty and welfare in the Irish context. Reflecting on the longer history on the role of Catholic ideas in Irish society, this article concludes with the suggestion that the frequent alignment of the institutional Church and successive governments in many areas implies the need for further analysis of the influence of class interests in determining policy and shaping attitudes, interests which transcend the lens of church versus state.
