The volume collects text-critical, exegetical and biblical-theological essays by Arie Zwiep on the Acts of the Apostles, dealing primarily with the opening chapters of Acts in the wider context of first-century Christianity and its Umwelt. The articles include treatments of the ascension and exaltation of Jesus in its early Jewish and early Christian context, the death and replacement of Judas Iscariot and the varying traditions of his death, the role of Judas and the Jews in the history of anti-Semitism, Luke's understanding of Pentecost and the outpouring of the Spirit, early Christian community life in Acts, the function of the early resurrection and exaltation Christology in Peter's Pentecost discourse, and Luke's special treatment of Paul in relation to the Twelve apostles in Jerusalem. The book contains previously published material (all thoroughly updated and revised), some articles appearing for the first time in English and two new essays.
