Pope John Paul II’s visit to Ireland in 1979 was an iconic moment in the history of twentieth-century Irish Catholicism. It has, however, received little detailed historical scrutiny. Based on state archival and hitherto unavailable diocesan material, this article contextualizes the visit by explaining the pastoral and leadership challenges that confronted the Irish hierarchy. Second, this article discusses how close the pope came to visiting Northern Ireland at the height of the Troubles. This was of concern not just to the hierarchy but to the Irish and British governments. Third, the organization of the visit, which was closely tied to the pastoral concerns of the Irish bishops, is surveyed. Lastly, the pastoral impact of the visit is considered. If the Catholic hierarchy hoped that the papal visit might arrest the declining institutional influence of the Catholic Church, reverse a quiet but growing faith crisis, or hasten a cessation of violence in Northern Ireland, then those expectations were misplaced. Ultimately, the pastoral impulse of the 1979 papal visit to Ireland was to preserve rather than renew the Irish Catholic tradition at a time when Irish Catholics were fixed on future material advancement rather than fidelity to their spiritual past.
