Book excerpt: Judging by the number of references to Holy Ghost in Luke's gospel and Acts, it is no wonder that Luke is designated as the “enthusiast in/for the Spirit” or that the Acts of the Apostles is called “the Acts of the Holy Spirit.” The Holy Spirit has also been one of the most constantly debated subjects among the many issues concerning Luke and/or Acts. This study will re-visit the topic of the Holy Spirit in Luke-Acts through a new perspective. Part of this volume discusses three contemporary understandings of Lukan pneumatology; that of J. D. G. Dunn, R. P. Menzies and M. M. B. Turner. These reflect three different positions in regard to this subject.
