Magic is an essential topic in the New Testament. Still, compared to other items of discussion in New Testament Studies, the significance of the theme of magic has been unjustly undermined, as indicated by David E. Aune. From all eight occurrences of magic in the New Testament, four are found in the Acts of the Apostles. Therefore, the Acts of the Apostles is the most significant source to understand magic in the New Testament. The purpose of this thesis is to demonstrate the significance of magic in the Greco-Roman era as the historical context to understand magic in the Acts of the Apostles. Since Christianity flourished in the Greco-Roman period, the understanding of magic in the Greco-Roman era is necessary to understand its confrontation with Christianity in the Acts of the Apostles. This article will examine the definition of magic, the positive and negative judgment of magic, the aspects of magic, which are the philosophy and sacraments related to the Acts of the Apostles, and the relation between magic and religion in the Greco-Roman Era.
