Must the church be either charismatic or sacramental? In this book, Terje Hegertun argues that she has the privilege of being both. The Day of Pentecost formed her identity and shaped her conviction of being lifted on the arms of grace and pushed forward by the power from on high. In the midst of her vulnerability and failure, the worldwide faith community is a composition of the Spirit. One of the greatest gifts the church may offer the world is simply to be church: a charismatic-sacramental fellowship, a dwelling place of God's Spirit. A church nurtured by graceful charismatic and sacramental gifts fosters a mature congregational spirituality distinguished by hospitable relations. Thus, the Spirit of God plays the main role of being the comprehensive principle of Christian unity across denominational lines. ""Professor Terje Hegertun comes to the task of constructing a pneumatological ecclesiology exceptionally well-qualified. A life-long Pentecostal minister and theologian, he is also fully conversant with Protestant, Catholic, and Orthodox traditions. Drinking from deep ecumenical wells of spirituality and theological insight, he presents to us a fresh and compelling account of The Spirit Driven Church."" --Veli-Matti Karkkainen, Fuller Theological Seminary ""In this rich study, Terje Hegertun convincingly argues for the Spirit's central role in all aspects of the church's life. Speaking from a Pentecostal background, his work is genuinely ecumenical, bringing together voices from different traditions in a fruitful interpretation and application of the biblical message of the Holy Spirit."" --Harald Hegstad, MF Norwegian School of Theology ""Hegertun offers us an impressively rich exploration of the church as constituted by the Spirit and, therefore, as an ongoing gift of the Triune God. This is an exciting contribution to ecumenical ecclesiology!"" --Frank D.
