This thesis explores the complexities of crisis management within Pentecostal churches in Australia, specifically focusing on the Australian Christian Churches (ACC) denomination. Crises in churches can arise from various sources, including internal issues such as moral failures, leadership incompetence, and governance challenges, as well as external pressures like natural disasters, regulatory changes, and evolving community expectations. The research investigates how churches can effectively navigate these crises while fulfilling their long-term mission and maintaining their role within the community. This study includes semi-structured interviews, set within a qualitative paradigm of theory-generation research, with lead pastors, ACC State Executive members, and principals of crisis management companies. The research assessed both past and current crisis management practices, identifying gaps between these practices and the established best practices within the broader field of crisis management. Existing gaps for Pentecostal churches included poor governance practices to prevent a crisis, no crisis management framework to manage a crisis, and little strategy to support key stakeholders in the post-crisis recovery period. From the data collected and from the analysis undertaken within the project, the Crisis Chain Model was developed, offering a structured framework for churches to prevent, mitigate, and manage crises. The thesis underscores the pivotal role of leadership and governance in shaping the outcomes of crises within churches. It highlights the importance of strategic planning, clear communication, and ethical decision-making as essential tools for effectively navigating crises. The findings provide actionable recommendations for churches, denominational leaders, and government agencies to improve crisis management practices, thereby bolstering the resilience and growth of church communities during challenging times. Additionally, the thesis addresses the inherent tension between churches as both bureaucratic entities and social communities, suggesting key areas for enhancing their organisational and bureaucratic responsibilities.
