The purpose of this dissertation is to determine what constitutes the abuse of power by leaders in Christian organisations and how it can be addressed, especially in a multicultural context. The theoretical and empirical research defines the abuse of power, especially in Christian organisations, and outlines the results. It determines the role that culture plays in the abuse of power and presents strategies that can be used effectively to prevent or deal with the abuse of power in different cultural contexts in Christian organisations. The cultures considered in the empirical research are English-speaking Canadians, Germans (from what was formerly West Germany), and white South Africans. In this research, the abuse of power, the aspects that define abusive leaders and the victims, and the effects of the abuse of power on the leaders, victims and the organisations are discussed. The literature and the responses from the research participants clearly confirm the existence of abusive leadership in Christian organisations. The characteristics that constitute an ethical Christian leader are defined and underlined by the responses from the respondents in this research: spiritual transformation, love, servant leadership, accountability, trust and forgiveness. Addressing the abuse of power in Christian organisations, specifically in a multicultural context is challenging. Leaders must be prepared to learn about and understand the cultures represented in the team. They also have a responsibility to challenge their team members to reflect on their cultural characteristics, to have healthy discussions and to form an organisational third culture that profits from the potential that each team member can contribute. / Philosophy, Practical and Systematic Theology / M.
