Pentecostalism has always been regarded as a movement that does not have all the ecclesiastical qualities that qualify it to be called a fully-fledged tradition alongside other major streams of Protestantism. Contrary to popular theologies that undermine the great role that the Pentecostal tradition can play in the global church, modern Pentecostal theologies agree that most of the misconceptions and assumption are misplaced because the Pentecostal tradition is a rich tradition with vital elements and symbols necessary to advance the ecumenical goal of unity and reconciliation. Based on this perception that Pentecostal ecclesiology is ecumenical, this research critically analyses Pentecostal ecclesiology as portrayed by Kärkkäinen in order to determine its ecumenicity or relevance to the ecumenical goals of unity, tolerance and reconciliation. This research confronts the paternalistic assumptions and misconception that regard Pentecostalism as simply a superstitious and naive sect which is only relevant to the lower class by bringing out the different elements and symbols within the tradition that are vital for the success and development of the global church in a modern global context. Some of the critical elements and symbols within the Pentecostal tradition that are explored within this study include÷ unity in diversity, the mission nature of the church, experiences of the Spirit as portrayed in its Pneumatological Christology and Soteriology, its rapid adaptation to new global south contexts and critical elements of inclusivity and plurality as portrayed in the foundations of the tradition. / Philosophy, Practical and Systematic Theology
