Pentecostal theology is marked by an inherent struggle for self-realization as well as unity and ecumenical integration. A realistic portrayal of worldwide Pentecostalism is confronted with homogeneous and romanticized depictions or false stereotypes. Global Pentecostalism and Pentecostalism in the West are intertwined in a significant theological and ecumenical manner that allows an ecumenical perspective focused on the West to shed light on the unity of Pentecostal theology, the relationship of Pentecostal theology to the ecumenical traditions, and the integration of Pentecostal theology in broader Christian commitments to social justice, peace, and the conservation of the creation. A particular point of convergence exists between Western and worldwide Pentecostal theology in the social activism of the movement. Contemporary Pentecostalism is in transition towards becoming a diversified contributor to the shape of global Christianity and the renewal of the theological agenda.
