'Thisbook identifies the impasse between classical Protestant and contemporary charismatic and Pentecostal pneumatologies as a fundamental theological problem. Its goal is to contribute a constructive pneumatological proposal for moving beyond this impasse, based on the resources of the theology of Christoph Friedrich Blumhardt (1842-1919). The disagreement is over the question of unmediated experience of the Holy Spirit. Luther's rejection of enthusiastic pneumatologies on the basis of a narrow concept of the mediation of the Word and a pessimistic anthropology became Protestant orthodoxy. In relation to classical Protestantism, the primary theological distinctive of charismatic theology is its strong affirmation of unmediated experience of the Spirit in Christian life and worship. The Pentecostal movements rapid growth in the past century has brought this difference to the fore. Christoph Blumhardts theology, which integrates pessimistic anthropology and unmediated experience, is well-suited to exploring the impasse between the two theological traditions. '
