In Protestantism the notion of faith is a core category. It expresses a specific and dynamic relationship between God and the human world. In the development of modern Protestant theology, processes of subjectivism and secularization, especially in the West-European context, have shaped the concept of faith. Since Protestant theology is increasingly influenced by globalization, the urgent task is to maintain a dialectical balance between: (1) the appreciation of personal involvement and human subjectivity in the life of faith, (2) the emphasis on the divine priority and initiative in the salvation process. The Protestant identity is at stake.
