There is no doubt that Jerusalem in the Bible is a city of great historical and theological significance. However, many modern readers are unaware that authors writing in Greek used its two names, Ierousalem and Heriosolyma. Among the few who used both names simultaneously is Luke the Evangelist. Commentators of this onomastic phenomenon have tried to explain this fact in various ways, referring to Luke's literary and theological choices or denying its meaning altogether. Krzysztof Mielcarek's monograph proposes a new view and explanation of this phenomenon in a theological-historical key. In his opinion, Luke's choices may be underpinned by his deep immersion in the world and terminological richness of the Septuagint, as well as important historical events that influenced the perception of the Holy City by the Hellenistic Jewish community and later also by the early Christians.
