Quantitative Leader-Member dynamics for church growth: Perez Chapel home cell

Background: Church growth remains a central theme in Pentecostal missiology, with small groups or home cells emerging as effective structures for qualitative and quantitative growth. Understanding the dynamics that foster this growth is critical, particularly within Pentecostal and Charismatic contexts. Objectives: This research investigates the impact of Leader-Member relationships on the growth of home cell groups at Perez Dome, a major branch of Perez Chapel International in Accra, Ghana. It focusses on how Leader-Member exchanges (LMX) influence spiritual, numerical, social and welfare growth. Method: Using a quantitative research design, the study adopts the LMX framework developed by Graen and Uhl-Bien. Data were collected through structured surveys targeting leaders and members of Perez Dome home cell groups. Statistical analysis explored correlations between LMX quality and the identified growth dimensions. Results: The findings reveal a significant positive relationship between high-quality LMX and home cell group growth. Spiritual growth was most strongly correlated, followed by social and welfare growth. However, the relationship between LMX and numerical growth was less pronounced, suggesting the need for additional strategies in evangelism and outreach. Conclusion: The study concludes that LMX dynamics are crucial for fostering sustainable growth in home cell groups. Key drivers include trust, open communication and welfare support, which enhance spiritual and social development. Contribution: This research contributes to Pentecostal missiology by demonstrating the relevance of LMX theory for holistic church growth. It provides actionable insights for African Pentecostal and Charismatic churches, emphasising Leader-Member relationship quality as a critical growth strategy.
