Some strange and unconvincing things are attributed to the Holy Spirit. Tragic consequences can often occur. This timely text attempts to distinguish the work of the Holy Spirit from such notable imposters as the human spirit, the conventional, and the demons. The study focuses on the two-volume work Luke/Acts. This, in turn, involves probing the tradition from which the teaching derives. The author has previously discussed the theology of Luke in the article "Interpreting Luke/Acts," The Literature and Meaning of Scripture (Inch and Bullock, eds.); and The Original Quest, subsumed under the corporate title Two Gospel Motifs. As for the Holy Spirit, consult the article "Manifestation of the Spirit" The Living and Active Word of God (Inch and Youngblood, eds.), and the Saga of the Spirit. Two pertinent appendices are included. First, concerning the obscure character of spirituality. Second, some random thoughts concerning the dogma of the Trinity. All things considered, the text is recommended for those who desire to put the work of the Holy Spirit in biblical perspective.
